Am I at Risk for Breast Cancer - Large

None of us likes to think about breast cancer and whether it could come into our life. But as with so many health issues, knowledge is power, so it’s smart to know your risk level.

Risk Factors for Breast Cancer

Some risk factors for breast cancer can’t be changed:

  • Gender: Breast cancer occurs nearly 100 times more often in women than in men.
  • Race or ethnicity: White women develop breast cancer slightly more often than African-American women.
  • Aging: Two out of three women with invasive cancer are diagnosed after age 55.
  • Personal history of breast cancer
  • Previous breast irradiation (refers to radiation treatment, not routine X-rays)
  • Family history and genetic factors: Having a mother, sister or daughter with breast cancer or ovarian cancer (or multiple family members on either your mother’s or father’s side with breast or ovarian cancer)
  • Some benign breast diseases
  • Dense breast tissue
  • Diethylstilbestrol (DES) exposure: Women who took this drug while pregnant (to lower the chance of miscarriage) are at higher risk.
  • Early menstrual periods, starting before age 12
  • Late menopause, after age 55

But there are also lifestyle-related risk factors for breast cancer:Am I at Risk for Breast Cancer - In Content  

  • Not having children, or having your first after age 30, may slightly increase your risk
  • Recent use (within 10 years) of oral contraceptives
  • Physical inactivity
  • More than one alcoholic drink a day
  • Long-term, postmenopausal use of combined estrogen and progestin (menopausal hormone therapy)
  • Weight gain and obesity, especially after menopause
  • Breastfeeding may slightly lower the risk, especially if it’s done for at least a year.

“Depending on what your risks are and what the elevation is, there are things to help deal with those risks,” says Thomas Heck, MD, surgical director at the breast center at Miami Valley Hospital North. “We can do everything from perhaps increasing monitoring (imaging and breast examinations) to offering risk-reducing medications.”

Assess Your Risk Level

There are breast risk assessment tools online that use knowledge of your family history to assess your personal risk level. But a discussion with your physician or health care provider is the best way to be proactive about dealing with your risk for breast cancer.

“Depending on what your risks are and what the elevation is, there are things to help deal with those risks,” says Thomas Heck, MD.

Some women will want even more knowledge. “For women who have a close relative who’s had breast or ovarian cancer, genetic testing is available to see if they have an inherited mutation in the BRCA1 or BRCA2 gene or other genetic mutations that can increase the chances for breast cancer to occur,” says Dr. Heck. While none of us like to think about breast cancer, knowing your risks is an important step to being prepared and knowing how best to protect yourself from the disease. Learn more about your personal risk level for breast cancer by taking this assessment or talking to your doctor or health care provider.
