>We don’t know. Based on the evidence that colleagues at McMaster University and I have generated, I have a concern it has something to do with HPV infection. We found that nearly all of the increase in colorectal cancer in young adults occurred in the distal colon, beyond the splenic flexure; and the closer to the anus, the greater the increase.
>In our analysis, females have had a greater increase in colorectal cancer than males. We also know that HPV is a cause of the increasing incidence of rectal cancer in American AYAs. In addition, from studies in Europe, South America, and Asia, persons infected with HPV had a higher incidence of colorectal cancer in general. I know of only three studies attempting to detect HPV in colorectal cancer specimens, in France, Denmark, and the Caribbean, and they had contradictory results.
>And if the increase is due to the HPV-related virus, we can prevent infection with the HPV vaccine. Thus, we should make a stronger and more urgent effort to ensure all adolescents and young adults are vaccinated
