Women are now being diagnosed with cancer more often than men in certain age groups, according to a new report from the American Cancer Society. Among adults aged 50-64, cancer rates are slightly higher in women, and women under 50 are almost twice as likely as men in the same age group to receive a cancer diagnosis.

The American Cancer Society's annual cancer trend report shows cancer mortality is decreasing but cancer rates are increasing in young adults and women.

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

Cancer cases are shifting from men to women in the U.S., and from older to younger adults, according to a new report from the American Cancer Society.

The cancer death rate declined by more than one-third over a three-decade period in the United States, though incidence rates for many types of cancer are rising in women and young adults, according to a new report.

The risk and incidence of cancer among people under 50 is also on the rise, according to American Cancer Society.
