A new report from the American Cancer Society shows an alarming trend: colorectal cancer rates are continuing to rise in younger adults. And those that are diagnosed are often in later stages, when treatment is more challenging.
Colorectal cancer continues to be one of the most common cancers in the country. In 2026, it’s estimated that over 150,000 Americans will be diagnosed. Worse, more than 55,000 will die from the disease.
While colorectal cancer rates have declined in older adults, the trend is different for younger people.
Rates have increased in adults under age 65, with the most notable rise seen in adults under age 50. The study found that the rate is increasing at around 3% per year in people ages 20-49.
Researchers also found that about 1 in 5 new colorectal cancer cases now occur in people younger than 55. In the mid-1990s, this age group accounted for only about 1 in 10 cases.
Because screening historically started later in life, younger adults have often not been screened when symptoms first appear. This can lead to a later diagnosis and a less-favorable prognosis.
Colorectal cancer often develops from polyps in the colon or rectum. These growths can be removed before they become cancerous.
A colonoscopy allows a doctor to find and remove these polyps during the same procedure. This makes colonoscopy one of the most effective tools for preventing colorectal cancer.
Screening can also detect cancer early, when treatment is most successful.
For most adults at average risk, colorectal cancer screening should begin at age 45. People with symptoms or a family history of colorectal cancer may need screening earlier.
Symptoms to discuss with a doctor include:
Colorectal cancer is often preventable with screening. A colonoscopy can detect problems early or prevent cancer before it starts.
If you are age 45 or older, or if you have symptoms or a family history of colorectal cancer, talk with your doctor about scheduling a colonoscopy.
Early screening may just save your life.
