7. You Have Symptoms Even Though You’re Younger
Many people think colorectal cancer is exclusively an older person’s disease. Age is indeed a major risk factor, and colorectal cancer is most frequently diagnosed in older adults. However, younger adults can develop it too. ([Institut National du Cancer][4])
That means persistent warning signs shouldn’t automatically be dismissed because someone is under 45.
The American Cancer Society’s 2026 guidance emphasizes that people with symptoms such as new bowel changes, rectal bleeding, or abdominal pain should seek medical evaluation, including younger people. ([Cancer.org][5])
The takeaway is simple: age does not make persistent symptoms irrelevant.
Risk Factors Matter Too
Symptoms aren’t the only reason to pay attention to colorectal cancer.
Some people have a higher-than-average risk because of their medical or family history.
Risk can be increased by factors such as:
-
A close relative with colorectal cancer or certain colorectal polyps
-
A personal history of colorectal polyps or cancer
