Breast cancer rising among younger women and Asian Americans, report finds
Americans have benefited from huge leaps in breast cancer treatment over the last two decades, but diagnoses are becoming more common, especially among younger women.
Americans have benefited from huge leaps in breast cancer treatment over the last two decades, but diagnoses are becoming more common, especially among younger women, according to a report published Tuesday by the American Cancer Society.
The new report shows that breast cancer mortality has decreased by 44% since the late 1980s. Rates of breast cancer, however, have increased by 1% every year since 2012. In younger women, rates have increased at a faster clip — by about 1.4% every year since 2021.

Among Asian American and Pacific Islander women under 50, breast cancer diagnoses have increased by 50% since 2000. Breast cancer rates in AAPI women younger than 50 are now higher than those in Black, Hispanic and American Indian and Alaska Native women of the same age group. In 2000, AAPI women under 50 had the second-lowest rates of breast cancer.
The reason why more women younger than 50 are getting breast cancer is not clear, but Reid said it’s likely due to modifiable risk factors such as environmental exposures in food, air or water, rising rates of obesity and sedentary lifestyles — the same risk factors thought to be causing higher rates of colorectal cancer in younger people.
Dr. Wendy Wilcox, chief women’s health officer at New York City Health + Hospitals, said that it’s likely not just one factor alone is driving the increase in younger breast cancer diagnoses.
