“Carcinoma is one of the five main types of cancer.

Carcinomas are the kind you hear about the most. When people say they have skin cancer, prostate cancer, breast cancer, lung cancer and so on, those are all carcinomas.

“Carcinomas are the most common type of cancer. They’re the ones most people immediately think of,” Dr. Shepard says.

That’s because 80% of cancer diagnoses are carcinomas.

Carcinomas are cancers that develop in your epithelial cells. Those are the cells at the outermost layer of the surfaces inside and outside your body. They’re the cells that surround your skin, as well as your organs and glands.”
