This article is for general information only. Cancer statistics can change over time and vary by country, age group, screening access and risk factors.

Bowel Cancer Worldwide

Colorectal cancer is a major global health issue. The World Health Organization describes colorectal cancer as one of the most common cancers worldwide and notes that its impact can be reduced through healthy lifestyle choices, risk factor awareness and timely diagnosis. :contentReference[oaicite:5]{index=5}

Age and Bowel Cancer

Bowel cancer risk increases with age, but it can also occur in younger adults. Because of this, persistent symptoms should be checked even if a person is younger than the usual screening age.

Why Screening Matters

Screening can help find colorectal cancer earlier, before symptoms appear. It can also find some polyps before they become cancer. CDC says most people should begin screening soon after turning 45, though people at higher risk may need earlier testing.

Symptoms Still Matter

Even with screening, symptoms should not be ignored. Blood in the stool, persistent bowel changes, abdominal pain, unexplained weight loss or ongoing tiredness should be discussed with a doctor.
