Young adults are likely not spending much time thinking about their vulnerability to disease, adopting an “it can’t happen to me” mentality that leads them to engage in habits that can increase their risk for certain illnesses, including breast cancer.

Breast cancer is the most common cancer in women, affecting about one in eight, according to the American Cancer Society. The National Breast Cancer Foundation (NBCF) reports that only 5 to 10% of breast cancer cases are linked to inherited mutations in genes such as BRCA1 and BRCA2. Thus, most breast cancer cases result from factors other than genetics, including lifestyle choices. Dense breasts, high hormone exposure, and obesity are risk factors for breast cancer. While adolescents may not think about preventive health care, they should educate themselves about how to lower their overall lifetime risk of developing breast cancer.

  • Exercise Regularly. At least two hours of recreational physical activity or sports each week can help lower stress and reduce future breast density. Moderate to vigorous activity each day is good for overall health.

  • A Balanced Diet. Focus on whole foods, vegetables, fruits, fiber, and whole grains, and reduce intake of inflammatory foods, sugary drinks, processed snacks, and red meat.

  • Avoid Alcohol. Avoiding alcoholic beverages during adolescence and into early adulthood can protect developing breast tissue. According to the National Cancer Institute, studies indicate that women who drank alcohol during their teen years may have an increased risk of breast cancer in adulthood.

  • Skip Cigarettes. Avoiding tobacco or quitting early can help reduce the risk of breast cancer. The NBCF reports that smoking at a young age significantly increases long-term cancer risk.

While not every case of breast cancer can be prevented, adolescents can take steps to protect themselves against it.
