Breast cancer deaths decline in US, but risks remain higher in lower-income countries

FRESNO, Calif. (KFSN) -- Breast cancer remains one of the most common cancer diagnoses among women nationwide.

A new report shows survival rates are improving in the United States and in other high-income countries.

The American Cancer Society estimates more than 320,000 new cases of breast cancer will be diagnosed in 2026.

While the disease continues to affect millions of women, the report found that breast cancer death rates in the United States have dropped by more than 40%.

The report examined breast cancer cases from 1990 to 2023.

"The incidence of breast cancer in the U.S. for the average woman is about one in eight, which is pretty high," said Dr. Christine Boyajian, an OB-GYN with Kaiser Permanente in Fresno.

Health experts point to early detection and advancement in treatment as key reasons for the decline in deaths.

"I think a lot of the shift towards improving survivability of breast cancer comes from improved screening and earlier detection of breast cancer," Boyajian said.

National data shows the five-year survival rate for breast cancer is nearly 92%. Doctors say routine mammogram screenings play a critical role in catching the disease early.

"The United States Preventive Services Task Force recommends that breast cancer screening begin at the age of 40 in those who are of average risk," Boyajian said. "Sometimes even in your 20s, but at least by your 30s, you should start talking to your provider."

However, the report also found that breast cancer continues to disproportionately affect women in lower-income countries. Researchers predict the disease will affect more than 3 million women worldwide by 2050.

Health experts say additional education and awareness could help improve survivability.

"I also think we need to do a little more education about having patients better understand why family history might be relevant and being open to sharing those details because sometimes, there are risk factors you may not think are risk factors," Boyajian said.

Doctors also stress that lifestyle choices can play a role in reducing cancer risk.

"Avoiding smoking is a big proponent of reducing your risk of breast cancer and cancer in general. Even alcohol use, you know, for trying to just maintain a healthier lifestyle and eating a more balanced diet," Boyajian said.
