“A risk factor is anything that increases your chances of getting a disease, such as cancer. But having a risk factor, or even many, does not mean that you are sure to get the disease. While you can’t change some breast cancer risk factors—family history, sex, race and aging, for example—there are some risk factors that you can control like exercise, diet, and weight. Studies have shown that risk for breast cancer is due to a combination of factors. The main factors that influence risk include being a woman and getting older. Most breast cancers are found in women who are 50 years old or older. ”
