Breast cancer caused by more than just genetics

[WCCO-TV, Nov. 23, 2018] Breast cancer is the most frequently diagnosed cancer, and the second most deadly kind of cancer found in women. Nearly one in eight women will develop breast cancer in their lifetime.

Ashley Daley is a certified genetic counselor with Allina Health’s Virginia Piper Cancer Institute. She says only 10 percent of women who are diagnosed develop breast cancer because of a genetic mutation or a hereditary cancer.

“For 90 percent of women we call it multi-factorial, meaning it’s complicated,” Daley said. “It’s an accumulation of risk over a lifetime.”
