Increasing incidence of colon cancer in patients <50 years old: a new entity?

Colorectal cancer (CRC) is the third most common cancer type in humans, the fourth most common cause of death because of cancer, and the second most common cancer type in terms of the number of individuals living with cancer 5 years after diagnosis worldwide, almost 694,000 people die from CRC annually. As it is expected is more frequent in older patients (patients older than 70 years old than in young patients (patients younger than 40 years old). The incidence of CRC in young adults is rising the last years and this fact arises the question; is this coincidence or is young adult CRC a real epidemy. In our current commentary we try and elucidate based on current data whether disease on young individuals is a new entity.
