Colon cancer rates rising among younger adults

Antibiotic use may be to blame for increase in younger colon cancer patients

One of the biggest questions surrounding Chadwick Boseman's death is how he could be so young, 43 years old, and have colon cancer. But unfortunately, deaths and diagnosis in younger patients is on the rise.

A recent review of cases by the American Cancer Society projected that 7% of all colon cancer deaths in 2020 would be to people under the age of 50.

Dr. Martin Luchtefeld, a  colon cancer specialist with Spectrum Health, says part of the reason may be linked to antibiotics.

"One of the interesting theories is that it's related to the amount of antibiotics this generation got at a younger age. We do know that taking antibiotics changes the microbiome in the colon being the normal amount of bacteria that live in the colon all the time.  And we do know that if you have different kinds of microbiome that may provide a better environment for colon cancer to grow," he said.

In addition some researchers say there could also be a link between the sexually transmitted HPV-16 and colon cancer. A study published by the National Institutes of Health found that HPV infection is common in patients with colorectal cancer. 

So when should you get screened for colon cancer? Well, health experts are not really sure. The American Cancer Society has lowered the screening age to 45 but the United States Preventive Taskforce and Medicaid which help govern when screenings should begin still say 50. 

 If your doctor suggests a screening at 45 you should check with your insurance to see the test is covered.
