Mayo Clinic Minute: Warning signs of colorectal cancer in younger adults

Colorectal cancer, the third-most common cancer in the U.S., has been rising among younger people for the past two decades. It is not one type of cancer but two cancers: colon cancer, which starts in the large intestine, and rectal cancer, which begins in the last part of the large intestine, known as the rectum.

Dr. Derek Ebner, a Mayo Clinic gastroenterologist, notes that colorectal cancer has been increasing in adults under age 50, particularly for rectal cancer. He says it's important to know the warning signs of colorectal cancer and to not delay medical treatment.
