The pros and cons of the flu shot!

Wondering how you can protect yourself from seasonal flu? Or just weighing the pros and cons of the seasonal flu vaccine? Here are some of the fast facts about flu prevention that you’ve been looking for.

  • Influenza causes more than 200,000 people in the U.S. to be hospitalized every year. Up to 49,000 people die each year from flu-related causes. Prevention is key.
  • Ideally, you should get the seasonal flu vaccine by Thanksgiving — the holiday season means hugs and kisses, which help spread the flu virus. However, getting vaccinated with the flu shot makes sense any time during flu season, which may last from September to May.
  • Think the flu vaccine can give you the flu? It can’t. The vaccine is made with a killed (flu shot) or weakened form of the flu virus (nasal flu vaccine), which can’t give you influenza. The nasal flu vaccine has caused transfer of the virus to others, but the risk of this happening is extremely low.
  • Concern that there’s a link between autism and the vaccine preservative thimerosal has prevented some parents from getting their kids vaccinated. Worry no more. Studies have found that there is no link between vaccines containing thimerosal and autism. And if you’re still worried, thimerosal-free flu vaccines are now the standard for children in the U.S. — and available to adults for the asking.
  • Stuck on the fact that you need to get vaccinated every year? There’s a good reason. Flu viruses change, so flu vaccines must change, too. Each year’s vaccine is unique, cultivated from the flu strains health officials believe will be most menacing that year.
  • It’s long been advised that people with allergies to eggs should not get the flu shot. However, the American College of Allergy, Asthma and Immunology says the vaccine contains such a low amount of egg protein that it’s unlikely to cause an allergic reaction in those with an egg allergy. If you have a severe egg allergy (anaphylaxis), talk to your doctor before getting the flu vaccine. Also, flu vaccines not made with the use of eggs are available.

    12 Reasons

    The best reasons to get vaccinated are to protect yourself and to protect the people around you. The details:

    1. You may no longer be protected. You may have received a vaccine as a child. But some vaccines require a booster if you want to remain protected. Protection may not be life-long for diseases like pertussis (whooping cough) or tetanus, which is usually given with the diphtheria toxoid. The CDC recommends a booster for the latter every 10 years after an initial childhood series.

     2. Getting vaccines helps protect your kids — especially babies too young for vaccines. Whooping cough vaccines are recommended for pregnant women (preferably between 27 and 36 weeks’ gestation) and people who have contact with young babies. The same is true for the flu vaccine. There’s no flu vaccine licensed for infants younger than 6 months old. “We call that creating a cocoon of protection around the baby,” Schaffner says.

    3. Some vaccines are just for adults. The shingles vaccine is a good example. Shingles (also known as herpes zoster or zoster) is caused by a reactivation of the chickenpox virus. It can cause a severe and painful skin rash. The risk for shingles increases as a person ages. The vaccine is recommended for adults 60 and older.

    4. You may need them when you travel. Headed to the developing world? You may run into illnesses you’d never find at home. The yellow fever vaccination is required for travel to parts of sub-Saharan Africa and tropical South America. The Saudi Arabian government also requires the meningococcal vaccination — but only for travel during the hajj, or annual pilgrimage to Mecca. You can check the CDC’s web site for details about what you may need for your destination.

    5. Everyone needs a flu vaccine, every year. The CDC recommends that everyone 6 months of age and older get a flu vaccine annually if they do not have a medical reason not to receive the vaccine. Each year’s vaccination is designed to protect against the three or four strains of influenza anticipated to be most commonly circulated in the upcoming flu season.

    6. Your kids have set an example. Most children don’t have a choice about getting shots. But why should they be the only one getting stuck with a needle? Want to show them that prevention through vaccination works? “Mom, dad, grandma, and grandpa should get their vaccinations just as children do,” Schaffner says.

    7. You didn’t get fully vaccinated as a child. Not everyone was, or is, fully vaccinated as a child. If you didn’t get vaccines for things like measles, mumps, and rubella or chickenpox (or varicella) as a child — or any of those diseases themselves — you need them as an adult. And don’t forget. Some older adults were born at a time when children weren’t vaccinated “as comprehensively as we vaccinate people today,” Schaffner says.

    8. Newer vaccines have been developed. Some vaccinations recommended for adults are fairly new. For instance, the FDA approved the first HPV vaccine and shingles vaccine in 2006. Although the rate of adults being vaccinated with newer vaccines is increasing, awareness remains a challenge, Wharton says.

    9. You’re going back to college. The downturn has forced many adults back to school. But many colleges require proof of routine vaccinations. You may not have those records. Your parents may not have those records. And your childhood doctor may no longer be practicing. It’s OK to repeat a vaccine. But, Wharton says, it’s “a hassle and cost” that could be prevented by keeping good records.

    10. You work in the health care profession. Health care providers are exposed to all sorts of potential infections, as well as blood and bodily fluids. Most are required to have not only a complete vaccination series and evidence of immunity, but also to get annual influenza vaccination. This includes things like measles, mumps, rubella (MMR), and hepatitis B.

    11. You’re sexually active with a number of partners. The hepatitis B vaccine is highly recommended. Hepatitis B can be transmitted from person to person through contact with blood, semen, and vaginal fluid. It is 50-100 times more easily to be infected by hepatitis B than by HIV. Your partner may not appear ill, but could be carrying the disease.

    12. You have asthma, heart, lung disease, diabetes, or other chronic disease. Or you smoke cigarettes. Or your immune system is otherwise compromised. The pneumococcal vaccine helps prevent serious disease such as pneumonia, meningitis, and blood infection caused by the bacterium Streptococcus pneumoniae. Get it because you may be at increased risk for these infections, Schaffner says.

    You decide is it right for you to protect yourself, your children and your community from passing the flu on to others?  I say yes unless you are allergic to it.  Think about it; and if you already get the flu vaccine don’t bother in thinking about it and get it when your due. 😉

Part 3 Knowing the facts and treatment on the FLU.

FLU FACTS:

-Both colds and flu usually last the same seven to 10 days, but flu can go three to four weeks; the flu virus may not still be there, but you have symptoms long after it has left. Allergy can last weeks or months.

-The winter flu epidemic will be coming around us again and in a given locality it reaches its peak in 2 to 3 weeks and lasts 5 to 6 weeks. Then is disappears as quickly as it arrived. The reason for this is not completely clear. The usual pattern is for a rise in the incidence of flu in children, which precedes an increase in the adult population.

-The flu virus can lead to serious complications, including bronchitis, viral or bacterial pneumonia and even death in elderly and chronically ill patients. Twenty thousand or more people die of the flu in the America each year. Know this that the frequency of human contact across the world and the highly infectious nature of the virus make this explanation difficult to accept. Moreover there is no evidence of persistent or latent infection with influenza viruses. In any case, this idea is not really very difficult from the notion that the virus circulates at a low level throughout the year and seizes its opportunity to cause an outbreak when conditions allow.

-Even harder to explain is why the flu disappears from a community when there are still a large number of people susceptible to infection. Than even harder than that is why flu is a winter disease, which is not fully understood or known. However, flu is spread largely by droplet (aerosol) infection from individuals with high viral level in their nasal and throat secretions, sneezing, and coughing on anyone close at hand. The aerosol droplets of the right size (thought to be about 1.5 micrometers in diameter) remain airborne and are breathed into the nose or lungs of the next victim.

-Situations in which people are crowded together are more commonly in cold or wet weather and so perhaps this contributes to spreading the flu at these times. It is interesting that in equatorial countries, flu occurs throughout the year, but is highest in the monsoon or rainy season. Enough about facts but onto logical thinking for when we or someone we know has it and what questions we might be asking ourselves.

LOGICAL QUESTIONS YOU MAY ASK YOURSELF:

Are the treatments for these illnesses the cold or the flu different? For any of these things, if it affects the nose or sinus, just rinsing with saline that gets the mucus and virus out is a first-line defense. It’s not the most pleasant thing to do, but it works very well. There are classes of medicines that can help the flu — Tamiflu and Relenza — antivirals that block viruses’ ability to reproduce and shorten the length and severity of the illness. But they have to be taken within 48 hours or the cat is proverbially out of the bag [because by then] the virus has done the most of its reproduction. For a cold or flu, rest and use decongestants and antihistamines, ibuprofen, acetaminophen, chicken soup and fluids. Zinc supposedly helps the body’s natural defenses work to their natural capacity and decrease the severity and length of a cold. Cells need zinc as a catalyst in their protective processes, so if you supply them with zinc, it helps them work more efficiently. You should also withhold iron supplements. Viruses use iron as part of their reproductive cycle, so depriving them of it blocks their dissemination. The majority of these infections are not bacterial and do not require [nor will they respond to] antibiotics. My rule of thumb is that a viral infection should go away in seven to 10 days. If symptoms persist after that, you’d consider if it’s bacteria like Strep or HaemophilusHYPERLINK “http://www.sciam.com/article.cfm?id=how-much-aids-vaccine-do” HYPERLINK “http://www.sciam.com/article.cfm?id=how-much-aids-vaccine-do”influenzae.

Those bacteria cause illnesses that are longer lasting and need antibiotics for ranging 3 to 14 days, depending on the med used. Is that treatment approach the same for kids versus adults? In general, the same rules apply: Most children will have six to eight colds a year in their first three years of life, and most are viral. Adults have 3 or more a year. It’s very easy to test for strep and for that you should have a [positive] culture [before treating with antibiotics]. The principle behind that is knowing the organism the doctor will know what antibiotic to use to fight off the bacterial infection and you won’t build up antibodies from the antibiotic that you didn’t need in the first place if you are given the wrong antibiotic in the beginning. Are the strategies for avoiding cold and flu different? Avoidance is very similar: Strict hand washing, not sharing drinking cups or utensils, and avoiding direct contact with people who are sneezing. Their transmission is similar. As long as someone has a fever, they have the possibility to transmit infection. After they’ve had no fever for 24 hours, they’re not infectious anymore. The U.S. Centers for Disease Control and Prevention (CDC) now recommends that just about everyone get the flu shot: kids 6 months to 19 years of age, pregnant women, people 50 and up, and people of any age with compromised immune systems. Is the shot beneficial to anyone who gets it? Unless you have a contraindication, there’s no reason not to get it=PREVENTION. Contraindications include egg allergy (because the vaccine is grown from egg products), any vaccines within a last week or two, and active illness at the time of your vaccine.

The best to do is PREVENTION so you can avoid the cold or flu in its active phase or post phase, so doing the following will help prevent it:

Live a healthy lifestyle overall=Good dieting, living good healthy habits and maintaining exercise with rest daily or 2 to 3 times a week including get a vaccine yearly for the flu with maintaining good clean anti-infection habits like as simply as washing the hands as directed above.

If you need help in being given the knowledge in how routinely lose weight if not maintain your good weight, knowing what foods are lean to leaner to leanest out of the 4 food groups, understanding why portions of meals including exercise balanced with rest is so important, how all 4 interact with each other impacting your metabolism rate, and keeping a healthier body with a higher chance of increasing your immunity with fighting off simple colds to possibly the flu when near someone contaminated with the virus and making this a regular part not just a few months to a year but for life then you came to the right blog. This is provided through Dr. Anderson and myself as your health coach if you need one in where we help you get started on this goal in your life. You can order Dr. Anderson’s book “Dr. A’s healthy habits” that provides the information on foods to help you lose the excess of weight with so much more in learning about the body to diseases in prevention and Rx. Most important, you make all the choices.   I needed to lose weight and lost 22 lbs. and hope to continue to lose another 20 lbs or so.

PART 2 LET’S PREPARE FOR THE FALL, WINTER and SPRING BUGS. WHAT ARE THEIR SYMPTOMS & WHAT TO DO, IF THE SYMTOMS ARE PRESENT.

People infected with an influenza or cold virus become contagious 24 hours after the virus enters the body (often before symptoms appear). Adults remain infectious (can spread the virus to others) for about 6 days, and children remain infectious for up to 10 days. Factors that may increase the risk of catching a cold are fatigue, emotional stress, smoking, mid-phase of the menstrual cycle, and nasal allergies. Factors that do not increase the risk of catching a cold include cold body temperature (Example being out in the cold or enlarged tonsils). General health status and eating habits do in that they have impact on your immunity and “fight or flight” in fighting off infection as opposed to getting sick due to a healthy body overall.

Watch for flu symptoms and in comparison here with the cold symptoms when trying to decipher what you have before going to the doctor:
FLU S/S: High Fever lasting 3 to 4 days.
Cold S/S: High fever is rarely.

FLU S/S: Prominent Headache.
Cold S/S: Headache is rarely.

FLU S/S: General aches and pains are often and can be severe.
COLD S/S: Slight in a cold for general aches and pain.

FLU S/S: Fatigue and weakness lasts up to 2 to 3 weeks.
COLD S/S: Fatigue and weakness is mild, if even present in the individual.

FLU S/S: Extreme Exhaustion is early and prominent
COLD S/S: Extreme Exhaustion is NEVER occurs.

FLU S/S: Chest discomfort and cough is common and sore throat may or may not be present..
COLD S/S: Chest discomfort and cough is mild; hacking cough with sore throat present sometimes.

Know not every patient with a flu or cold is the same but in knowing in general common symptoms here’s some:

-Common symptom-Stuffy nose is present sometimes

-Common symptom-Diarrhea and vomiting(more common for children)

*Note weakness and tiredness can last up to a few weeks with the Flu.

Regarding cold symptoms also be aware for these specifics, which include:

-Sore throat-usually is going away in about a 1-3 days.

-Nasal Symptoms=runny nose and congestion to follow, along with a cough by the 4th or 5th day.

-Fever is uncommon in adults with a cold but a slight fever is possible but note in children they can likely have a fever with their cold.

-With the symptoms above you can also have the nose that teems with watery nasal secretions for the first few days later these become thicker and darker. Dark mucus is natural and does not mean you have developed a bacterial infection, such as a sinus infection.

**Know several hundred different viruses may cause your cold symptoms. A virus cannot be treated with an antibiotic since they only are treatment for bacterial infections.*

Let’s prepare ourselves in knowing factors for prevention of these 2 BUGS THE COLD and THE FLU (particularly) with knowing what to do when you or someone in the home has it.

Now let’s review what we know which is the common cold and the types of flu (Types A,B, and C) are with knowing their symptoms (the cold versus the flu) and The Flu statistics of how many are affected yearly with what complications can arise, based on Part 1 of yesterday’s article on the cold and flu lets now start in letting us be aware of factors in prevention of a cold vs. flu.

The biggest factor in prevention of the COMMON COLD or THE FLU and a great healthy habit and that would be washing your hands with soap and water often, especially:

  • Before, during, and after preparing food
  • Before eating
  • After using the bathroom
  • After handling animals or animal waste
  • When their hands are dirty
  • When someone in your home is sick                                                                                                                                                         

         ***FOR AVOIDANCE IN GETTING THE FLU OBTAIN YOUR VACCINE YEARLY!***

Keep your face off-limits. The flu virus enters through the eyes, nose, and mouth, so those with the flu or a simple cold should never touch their faces unless they’ve just washed their hands.

Avoid sharing food, drinks, and utensils.   Do not share drinking glasses-and to break off portions of food and to pour off beverages before consuming them.

Keep tissues handy. The flu spreads when infected people cough or sneeze. So adults use them and encourage your kids to cough and sneeze into a tissue or their upper arm if tissues aren’t available. (Coughing into a bare hand can also spread germs if kids touch something before they can wash.)

Ask your doctor about antiviral medications. Although not approved for use in children under 1, these drugs can be used in older children & adults to prevent influenza or even can treat the flu in the first 2 days of onset.****Recommended is to check with your MD on any changes with diet or exercise especially if diagnosed already with disease or illness for your safety.****    1-Wikipedia “the free encyclopedia” 2013 website under the topic Influenza.3-Web MD under “COLD, FLU, COUGH CENTER” “Flu or cold symptoms?” Reviewed by Laura J.

Live a healthy lifestyle. MOST IMPORTANT!!! A healthy lifestyle may help prevent you from getting sick & some hints:

  • Use those wipes! Flu germs can live for several hours on surfaces such as countertops and doorknobs. Wipe down contaminated objects with soap and water.
  • Let your kids, including adults stay home when they’re sick. They’ll feel better sooner and won’t pass their illness on to their classmates or for an adult passing it on to colleagues at work especially the first few days when contagious so don’t go into work those few days.
  • Since the age of 6 months, Olivia’s bedtime routine has been the same – play time, bath, pajamas, bottle, story, then bed. Keeping thi                                 Make sure you or your sick child who is sick gets enough sleep.       Too little sleep can cause the feeling of run-down and lower the immunity. Yet a National Sleep Foundation poll found that most children need 1 to 3 more hours of sleep than they’re getting every night usually. How much should they be getting? Experts recommend 11 to 13 hours a night for preschoolers and kindergartners and 10 to 11 hours for school-aged children. Adults 8 hours of sleep a day if not more when sick with a cold or the flu. How to make sure this can be accomplished: Establish an earlier-bedtime routine, this just takes disciplining by the parent or yourself if an adult.
  • Keep your distance. Stay clear of people who are sick-or feel sick.
  • What to do when you have the cold or, worse, the flu:

 

Keep tissues handy. The flu spreads when infected people cough or sneeze. So adults use them and encourage your kids to cough and sneeze into a tissue or their upper arm if tissues aren’t available. (Coughing into a bare hand can also spread germs if kids touch something before they can wash.)

LET’S PREPARE FOR THE FALL, WINTER and SPRING BUGS. WHO ARE THEY & WHAT ARE THEIR STATISTICS? Part 1

Those bugs that are common in fall, winter and spring are 2 Viruses =The COLD and THE FLU.

HOW THEY ARE DIFFERENT:

Both influenza and the common cold are viral respiratory infections (they affect the nose, throat, and lungs). Viruses are spread from person to person through airborne droplets (aerosols) that are sneezed out or coughed up by an infected person, direct contact is another form of spread with infected nasal secretions, or fomites (contaminated objects). Which of these routes is of primary importance has not been determined, however hand to hand and hand to surface to hand to contact seems of more importance than transmission. The viruses may survive for prolonged periods in the environment (over 18 hours for rhinoviruses in particular=a common virus for colds) and can be picked up by people’s hands and subsequently carried to their eyes or nose where infection occurs. In some cases, the viruses can be spread when a person touches an infected surface (e.g., doorknobs, countertops, telephones) and then touches his or her nose, mouth, or eyes. As such, these illnesses are most easily spread in crowded conditions such as schools.

The traditional folk theory that you can catch a cold in prolonged exposure to cold weather such as rain or winter settings is how the illness got its name. Some of the viruses that cause common colds are seasonal, occurring more frequently during cold or wet weather. The reason for the seasonality has not yet been fully determined. This may occur due to cold induced changes in the respiratory system, decreased immune response, and low humidity increasing viral transmission rates, perhaps due to dry air allowing small viral droplets to disperse farther, and stay in the air longer. It may be due to social factors, such as people spending more time indoors, as opposed to outdoors, exposing him or her “self” to an infected person, and specifically children at school. There is some controversy over the role of body cooling as a risk factor for the common cold; the majority of the evidence does suggest a result in greater susceptibility to infection.

The SIMPLE COMMON COLD:

The common cold (also known as nasopharyngitis, rhinopharyngitis, acute coryza, head cold) or simply a cold is a viral infection of the upper respiratory tract which primarily effects the nose. There are over 200 different known cold viruses, but most colds (30% up to 80%) are caused by rhinovirusesThis means you can pass the cold to others, so stay home and get some much-needed rest for yourself and not passing it on to others for the contagious period at least.

If cold symptoms do not seem to be improving after a week, you may have a bacterial infection, which means you may need antibiotics, which only kill bacterial infections not viral.

Sometimes you may mistake cold symptoms for allergic rhinitis (hay fever) or a sinus infection (bacterial). If cold symptoms begin quickly and are improving after a week, then it is usually a cold, not allergy. If your cold symptoms do not seem to be getting better after a week, check with your doctor to see if you have developed an allergy or inflammation or the sinuses (sinusitis).

Influenza is commonly referred to as “the flu”, this is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses. The most common sign or symptom are chills, fever, runny nose, coughing, aches and weakness to headache and sore throat. Although it is often confused with other influenza-like illnesses, especially the COMMON COLD, influenza is a more severe illness or disease caused by a different virus. Influenza nausea and vomiting, particularly in children but these symptoms are more common in the unrelated gastroenteritis, which is sometimes inaccurately referred to as “stomach flu” or “25 hour flu”. The flu can occasionally lead to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, even for persons who are usually very healthy. In particular it is a warning sign if a child or presumably an adult seems to be getting better and then relapses with a high fever as this relapse may be bacterial pneumonia. Another warning sign is if the person starts to have trouble breathing.

Each year, 10% to 20% of Canadians are stricken with influenza. Although most people recover fully, depending on the severity of the flu season, it can result in an average of 20,000 hospitalizations and approximately 4000 to 8000 deaths annually in Canada. Deaths due to the flu are found mostly among high-risk populations, such as those with other medical conditions (such as diabetes or cancer) or weakened immune systems, seniors, or very young children. There are 3 types of influenza viruses: A, B, and C. Type A influenza causes the most serious problems in humans and can be carried by humans or animals (wild birds are commonly the host carriers). It is more common for humans seem to carry the most with ailments with type A influenza. Type B Influenza is found in humans also. Type B flu may cause less severe reaction than A type flu virus but for the few for the many can still be at times extremely harmed. Influenza B viruses are not classified by subtype and do not cause pandemics at this time. Influenza type C also found in people but milder than type A or B. People don’t become very ill from this Type C Influenza and do not cause pandemics.

The common cold eventually fizzles, but the flu may be deadly. Some 200,000 people in the U.S. are hospitalized and 36,000 die each year from flu complications — and that pales in comparison to the flu pandemic of 1918 that claimed between 20 and 100 million lives. The best defense against it: a vaccine once a year.

Part 2 Cancer-tumor types with diagnosis & treatment.

Differences between tumors are as follows:

Benign Tumors ones are the following:

Encapsulating (the big answer to resolution of a tumor like this is this a tumor that is surgical to remove or can radiation or chemo decrease the size of it to nothing).

Non metastasizing-meaning it hasn’t spread anywhere.

Well – Differentiated-meaning easy to detect.

Slow – growing (just what is says)

Malignant Tumors ones are the following:

Invasive,Metastasizing,FrequentlyUndifferentiated,OftenRapidGrowing.

Know that carcinogenesis is the process of inducing a malignant tumor in an animal or human. Much of the research in carcinogenesis resolves around deoxyribonucleic acid (DNA), the influence of carcinogens on DNA, and the genes that are involved in differentiation (of this growth vs normal tissue of the body) and control of cancerous cell growth.

There is viral and chemical carcinogenesis.   Both RNA and DNA viruses have been identified as causing natural and experimental tumors. Research has shown herpes viruses are DNA viruses. For almost every herpes group there is some experimental or epidemiological evidence linking it to human malignancy. Example Epstein-Barr viruse has been associated with Burkitt’s Lymphoma in West African children and nasopharyngeal cancer among Asian populations. Herpes simplex virus-1 has been linked to oral cancer and herpes simplex virus-2 to cervical cancer. All herpes viruses share a characteristic ability to remain latent within the body over long periods. Although they may be found throughout the body, CMV (cytomegaloviruse) infections are frequently associated with the salivary glands in humans and other mammals. Other CMV viruses are found in several mammal species, but species isolated from animals differ from HCMV in terms of genomic structure, and have not been reported to cause human disease.

The RNA viruses, also called oncoviruses or retroviruses induce leukemia, lymphoma, and mammary tumors in animals. To complete their natural cycle, these viruses must manufacture a viral DNA that is then integrated into the host cell DNA. To do this they produce an enzyme and the enzyme is able to use RNA as a template to produce DNA. Since these viruses can remain latent in a cell for long periods of time, it is only by identifying the enzyme or the viral DNA that scientists are able to detect cells infected with these viruses. This enzyme has been identified in some human leukemia and lymphoma cells.

In addition, approximately 20 oncogenes have been identified with these RNA viruses and some of these oncogenes have also been detected in human bladder cancer cells, Burkitt’s lymphoma, and promyelocytic leukemia.

There is also radiation carginogenesis. There is external radiation; take Leukemia which was the first cancer related to radiation exposure that was seen in the atomic bomb survivors. Within 6-8 years after the bomb, the incidence rates of leukemia increased to levels well above those seen in the Japanese population who were not exposed. The peak was highest from 1950 to 1952, at which time the incidence was 116:100,000, as compared with 3-4:100,000 to the unexposed population.

Internal Emitters – One of the most famous classics is that of the luminescent instrument – dial painters. The paint was used to create luminescent faces on watches and clocks containing radium. While painting, the workers licked the brushes and thus ingested the radium. Radium, when ingested is deposited in bone and tends to remain there.) Among this group, bone cancer or osteogenic sarcoma, a rare tumor, became prevalent. With this type of knowledge it led to limitations on surface testing of atomic weapons. Atomic weapons contain radioactive compounds that can become deposited in the bone.

Ultraviolet radiation or the Sunlight – One of the most obiquitous forms of radiation that every person is exposed to is the sunlight. Ultraviolet rays do not penetrate deeply. Most statistics on cancer do not include skin cancer due to it being treatable (the easiest cancer to treat on average). Another more dangerous type of cancer is melanoma that has been linked to sunlight exposure.

Tumor classification shows because the study of tissues originates with the study of their development in the embryo, the class of the tumor is often based on the tissues from which the tumor is derived.

Grading the cancer, besides classifying the tumor according to the tissue origin the pathologist will classify it looking at other characteris- tics. This aspect is Grading the cancer from level 1 or 2 or 3 or 4. If cells of classification in the tumor look like the mature cells of the tissue than the tumor is well differentiated=Grade 1. This type of tumor generally has a better prognosis compared to a tumor that is poorly differentiated or does not resemble the tissue from which it originated. Sometimes a poorly differentiated tumor is called anaplastic. An anaplastic tumor would have the highest grade of 4. Remember even though tow tumors might be similarly classified and have identical grades, in two different individuals the tumors might act differently. Because each patient is unique, has a different history, different immune responses, and different reserves, similar tumors might act very differently.

DIAGNOSIS

A definitive diagnosis of cancer can only be made after an examination of tissue obtained from a surgical procedure or biopsy. Biopsies can be excisional, meaning the whole lesion is removed, or incisional in which only part of the presumptive tumor is removed. Specimens can also be obtained from a needle biopsy. In this a core of tissue is drawn up in a needle.   Cytological examination of exfoliated cells, as done in a pap smear, can lead to a presumptive diagnosis of cancer but often a surgical biopsy will be performed to confirm the diagnosis. Often the patient undergoes many other diagnostic tooling procedures besides the biopsy in the attempt to determine the nature and extent of the illness=from blood tests, diagnostic x-ray studies, and endoscopic procedures. These tests with the biopsy done are used to evaluate the extent of the disease in the patient. This process of determining the extent of tumor in an individual is called staging.

Treatment

Cancer treatment can be surgery, chemo or radiation or even all 3.
