THE BIG PICTURE
Rates of colorectal cancer in adults under 50 have been climbing for two decades, even while rates continue to fall in older adults. Researchers have not identified one single cause. Instead, the evidence points toward a cluster of everyday, potentially changeable factors.

Some symptoms deserve medical attention, regardless of age.
Rectal bleeding or blood in the stool
A change in bowel habits lasting more than a few weeks
Unexplained abdominal pain or cramping
Unintended weight loss
Iron-deficiency anemia with no clear cause
Any of these symptoms is worth discussing with a doctor.
Guidelines now recommend colorectal cancer screening starting at age 45 for average-risk adults — earlier than many people realize. If you have a family history or other risk factors, your doctor may recommend starting even sooner.
