Colon Cancer Rates on the Rise in Women Under 50

The latest American Cancer Society guidelines now recommend women aged 45 and older get screened for colon cancer. While traditionally screening for colon cancer has started at age 50, recent trends indicate a rising incidence of colon cancer in younger adults. Colon cancer is now the 2nd leading cause of cancer deaths in women under 50, behind breast cancer.
