October is Breast Cancer Awareness Month and health professionals are urging women to get screened at earlier ages than previously suggested.

After skin cancer, breast cancer is the most diagnosed form of cancer for women in the U.S.

Dr. Anne Gayman, a family medicine physician at Kaiser Permanente in Seattle, said there has been an increase in breast cancer rates in women in the 40- to 50-year age range. She noted previous recommendations called for women to speak with their health care provider after age 40 about when to start screening.

“These new recommendations from the United States Preventative Services Task Force state that all women should begin screening now at age 40, and repeat screening every other year through age 74,” Gayman explained.

About one in eight women will develop breast cancer in their lifetime, according to the American Cancer Society, which also said breast cancer rates in Washington state are higher than the national average and screening rates are lower. The state has the ninth-highest cancer rate in the country, and the 10th-lowest screening rate.

Gayman said it is unclear what is driving up the numbers for younger women.

“We don’t know, but we know that younger women can get often quite aggressive forms of cancer,” Gayman pointed out. “These new recommendations help us to get more young women having regular screenings, which can help to intervene earlier.”

Gayman emphasized there are new treatments to target breast cancer and more research is being done because some forms are still hard to treat and acknowledged some big improvements in breast cancer survival rates.

“A lot of that is thought to be due to the increased rates of screening, because the earlier we catch breast cancer the more treatable it is, right?” Gayman added. “If we can catch it before it’s moved outside of the breast, your prognosis is much better.”
