Symptoms of Colorectal Cancer

by Michelle Badash, MS

En Español (Spanish Version)

It is important to remember that very often there are no symptoms of colorectal cancer until the cancer is advanced. This is why it is important to begin and maintain a program of regular screening as recommended by your doctor. Common symptoms of colorectal cancer include:

Change in bowel habits
Blood, either bright red, or black and tarry, in the stool
Stools that are narrower than usual
Diarrhea, constipation, or feeling that the bowel does not empty completely
General abdominal discomfort, such as frequent gas pains, bloating, fullness, and/or cramps
Unexplained weight loss
Constant feeling of fatigue or tiredness
