A new report points to a notable increase among U.S. women under 50. Experts point to a few likely causes.<\/p>\n

Siobhan Donovan was a runner who ate her vegetables, didn\u2019t smoke and drank alcohol only socially. She had no family history of cancer. So when she experienced some swelling in her breast near the end of what she called \u201ca textbook-easy pregnancy\u201d with her third child, she and her doctors expected nothing serious.<\/p>\n

They were wrong. Ms. Donovan, who was 33 at the time, had metastatic breast cancer that had spread to her bones.<\/p>\n

\u201cI was really just in shock,\u201d she said, adding that back then she didn\u2019t even know the meaning of the word \u201cmetastasis.\u201d<\/p>\n

Like Ms. Donovan, a growing number of younger women are being diagnosed with breast cancer, according to new estimates released Thursday by the American Cancer Society. Between 2012 and 2021, the incidence rate of breast cancer overall increased by about 1 percent each year, while the incidence rate among women under age 50 increased by about 1.4 percent each year. Patients with \u201cyoung-onset breast cancer\u201d \u2014 which clinicians typically define as diagnosed before the age of 40 \u2014 are more likely than older patients to have aggressive forms of the disease, said Dr. Ann Partridge, interim chair of medical oncology at the Dana-Farber Cancer Institute in Boston.<\/p>\n<\/div>\n<\/div>\n

The increase in breast cancer rates among younger patients is occurring as the incidence of other early-onset cancers \u2014 including colorectal, gastric, kidney and liver cancer \u2014 is also on the rise, though cancer among patients under 50 is still relatively rare overall, Dr. Partridge said.<\/p>\n

In 2024, there were just under 51,000 new invasive breast cancer cases among women under 50, compared with about 260,000 cases among women 50 years of age and older, according to American Cancer Society statistics<\/a>.<\/p>\n
