Why Young Patients are Having Colorectal Cancer?

Abstract

Starting around 1990, incidence increased in this age group (20–49 years) from 8.6 per 100,000 to 12.5 per 100,000. The largest absolute increases in incidence have occurred among 40–49-year-olds, from 18.2 per 100,000 in 1992 to 26.5 per 100,000 in 2015. Similar increases have been reported across the world [3]. Asian studies (institutional reports) showed similar trends in patients less than 40 years of age, with a prevalence of 19.5-28.6%, which is clearly higher than that in the USA [46] meanwhile in Mexico at the National Cancer Institute, we reported an incidence of 22.8% [7].
