symptoms of colon cancer onset
Also, younger-onset colon cancer appears to affect African-Americans more often than other groups. The most common symptoms of colon cancer are rectal bleeding and lower abdominal cramping. Other telltale symptoms may include a change in stool consistency, constipation, diarrhea or weight loss. Blood tests that reveal new-onset anemia can often signal the presence of a colon tumor. Unfortunately, colon cancer often is not considered as a cause of such symptoms in people who are younger than 50. As a consequence, colon cancer diagnosis can be delayed. Statistics show that colon cancer tends to be diagnosed at later stages in young people.
