Colon Cancer Increasing Faster than Other Early Onset Cancers

UNITED STATES, JUL 17 – Colorectal cancer diagnoses have risen 2% annually since 2011 in U.S. adults under 50, linked to lifestyle and genetic factors, according to a JAMA review.

  • On Thursday, a JAMA review found gastrointestinal cancer to be the fastest-growing type among U.S. adults under 50.
  • Dr. Kimmie Ng said most early-onset GI cancers link to lifestyle factors, while cases of pancreatic, stomach and esophageal cancers are also rising.
  • Fifteen to thirty percent of people with early-onset gastrointestinal cancer carry hereditary genetic mutations, Ng’s review found, and actor Chadwick Boseman’s case underscores early-age risk.
  • Despite more aggressive treatments, Ng said younger patients often have worse outcomes, and fewer than one in five 45-49-year-olds were screened in 2021.
  • Ng concluded that taken together, these two reviews are a call to action for further research on why rates of GI cancers are increasing in younger adults, and authors urge new screening methods for pancreatic, stomach and esophageal cancers.
