“While researchers are still working to fully understand breast cancer’s causes to ultimately prevent the disease entirely, they have identified several proven risk factors for breast cancer—including many that are potentially modifiable. According to a 2017 American Cancer Society (ACS) study, nearly 42 percent of cancer diagnoses and 45 percent of deaths in the US are linked to controllable risk factors for cancer. For breast cancer specifically, ACS estimates that about 30 percent of postmenopausal breast cancer diagnoses are linked to modifiable risk factors. When it comes to breast cancer, there are a number of ways you can protect yourself. While it’s important to note that several factors shaping your personal lifetime risk of breast cancer maybe controllable there are others completely out of your control—among them genetics, family history, race, ethnicity, breast density, being born female—BUT lifestyle choices can play a role. ”
