Rising GI Cancers Among the Young: What’s Going On?
Cancer usually affects older adults. But experts are now seeing a rise in GI cancers in people under 50. These include cancers of the stomach, colon, and rectum.
GI cancers in young people are becoming more common. Though still rare compared to older adults, these early-onset cases are increasing at a worrying rate. In fact, colorectal cancer is now the top cause of cancer-related deaths among young men in the U.S., and second among women.
The exact reason isn’t clear. But experts suggest that obesity, poor diet, alcohol, smoking, and microplastic exposure could all play a role. New research also points to gut bacteria changes, stress, and inflammation as possible triggers.
Why the Rise in Colorectal Cancer?
Data from 2010 to 2019 shows early-onset colon cancers rose by nearly 15% in the U.S. Similar trends are seen in Europe. For example, colon cancer rose 8% among 20–29 year olds in just over a decade.
One expert, Dr. Anton Bilchik, says most young patients don’t show typical risks like obesity or family history. He believes processed foods, lack of exercise, and stress may damage the microbiome and immunity. This may cause inflammation and increase cancer risk.
Despite the rise, total cases in younger adults remain lower than in older adults. Still, doctors urge earlier screening and public awareness, especially for groups like Black and Hispanic Americans.
How to Lower Risk and Catch It Early
Some GI cancers may be linked to infections. A study found that 76% of future stomach cancer cases may result from Helicobacter pylori, a preventable bacterium. This shows that prevention and education can make a big difference.
To lower the risk of GI cancers in young people, experts recommend early screenings. Screening now starts at age 45, or earlier for those with a family history. Lifestyle changes are also key exercise, limit alcohol and red meat, stop smoking, and treat vitamin D deficiency.
GI cancers in young people may be rising, but steps like early detection and healthy living can help fight back.
