Colorectal cancer is becoming more common in younger adults.

The rate of people under age 50 rose more than 11% from 2004 to 2014. And colorectal cancer among people ages 20 to 34 is expected to increase 90% by 2030.

The actual number of people in these age groups who develop colorectal cancer remains small. But younger people are rarely screened for colorectal cancer, so when it does occur, it tends to be found at more advanced stages requiring more aggressive treatment.
