Low risk before 50: Colon Cancer and Age 90% of new cases and 95% of deaths from colon cancer occur in people 50 or older. However, colon cancer does not discriminate and can happen to men and women at any age. While rates for colon cancer in adults 50 and older have been declining, incidence rates in adults younger than 50 years has been increasing. Just launched! New pages with tons of information about young-onset colon cancer, who’s at highest risk and resources for you. Check them out! Colon Cancer and Ethnicity and Race Jews of Eastern European descent (Ashkenazi Jews) may have a higher rate of colon cancer. Partly because of disproportionate screening, African-American men and women have a higher risk of developing colon cancer and a lower survival rate (about 20% higher incidence rate and 45% higher mortality rate) compared to Caucasians, Asians, Hispanics and Native Americans. The risk of death is also increased for Native Americans and Alaskan Natives. Colon Cancer and Family History People with a first-degree relative (parent, sibling, or children) who has colon cancer are between two and three times the risk of developing the cancer than those without a family history.
