Young people often overlook health risks, but colon cancer is rising among Gen Z and Millennials. Once thought to primarily affect older adults, cases in individuals aged 20–49 have doubled since the 1990s.

Known as the “silent killer,” colon cancer may show few symptoms until it reaches an advanced stage. The Colon Cancer Coalition reports it as the second leading cause of cancer deaths, with 30% of cases affecting those under 55. People born after 1990 face twice the risk of colon cancer and four times the risk of rectal cancer compared to those born in 1950.

Experts link rising cases to obesity, poor diet, inactivity, and family history. Early screening, a fiber-rich diet, and a healthy lifestyle can reduce risk. Since young patients are often diagnosed late, self-advocacy and early symptom awareness are crucial in preventing fatal outcomes.
