Increasing Incidence of Colorectal Cancers in Young People

A review of the nearly 400,000 reported cases of cancers of the colon and rectum between 1975 and 2010 reveals some interesting trends. Overall, the incidence of colorectal cancers declined by just under 1% per year, due to a steady decline in persons 50 years of age or older. However, the incidence of colorectal cancers rose in the youngest age group; persons aged 20-34. Based on current trends, rates of colorectal cancers in this age group will nearly double by 2030.

The current study provides no information regarding the cause of the upward trend. But this is how science works; based on an observation, (a rising rate of colorectal cancers in young people) a hypothesis must be formed and further study undertaken to test it.

Perhaps by 2030 we'll know why colorectal cancers are increasing in young people, and also know what to do about it. The optimist in me hopes so.
