Hereditary Breast and Ovarian Cancer Week

Why Knowing Your Risk Matters

About one in eight women will be diagnosed with breast cancer in her lifetime, according to the American Cancer Society. During Hereditary Breast and Ovarian Cancer (HBOC) Week (September 28 – October 4), Aspirus Health is reminding women that understanding their personal risk is one of the most powerful tools for prevention and early detection.

 

“Being born female and getting older are the most common risk factors,” said Cecilia Stroede, MD, breast surgeon with Aspirus Health. “But there are many others we also need to think about, such as family history, having dense breast tissue, lifestyle habits, alcohol use, and certain genetic mutations.”

 

One of the most important of these additional risk factors is genetics. Jessica Gaffaney, PA, breast health specialist with Aspirus Health, explained, “About five to 10 percent of breast cancers are hereditary, related to a genetic mutation. The most well-known are BRCA1 and BRCA2, which can significantly elevate the risk of breast and ovarian cancer, but there are other genes that can also contribute.”

 

Among those at higher risk are women of Ashkenazi Jewish heritage. The National Cancer Institute notes that about one in 40 individuals of Ashkenazi Jewish ancestry carry a BRCA1 or BRCA2 mutation, compared to a much lower rate in the general population.

 

Risk is not only tied to genetics. Past medical history can also increase risk. For example, women who received chest wall radiation before age thirty may face a lifetime breast cancer risk greater than 50 percent, according to the National Cancer Institute. Certain findings on a breast biopsy can also be markers of elevated risk.

 

But risk is not limited to what happens in a hospital or clinic. Everyday lifestyle choices make a difference too. The American Cancer Society reports that about one in seven breast cancers may be linked to alcohol consumption. “That is why it is important to pair regular screenings with healthy habits, like eating well, staying active, and managing stress,” Dr. Stroede explained.

 

And while screening technology moves forward, one constant remains: family history matters.

 

“You inherit half your genes from your dad, so cancers on the paternal side are just as important as the maternal side,” Dr. Stroede said. Gaffaney added, “Talk to family members, know your breast density, and do self-breast exams. If something feels new or concerning, do not ignore it.”

 

During HBOC Week, Aspirus Health encourages individuals to talk with their health care provider about their personal and family history of cancer, learn about genetic counseling, and take steps toward healthier lifestyle choices.
