Symptoms of colorectal cancer
How do I know if I have colorectal cancer?
There’s only one way to know. Get screened.
Colorectal cancer doesn’t always display symptoms. You may not be able to tell there’s something wrong until the cancer has metastasized, making it much harder to treat.
Early warning signs
- Bleeding from the rectum (many mistake this for hemorrhoids)
- Blood in or on your stools (may be dark red or black)
- Diarrhea, constipation, or a combination of both, sometimes with mucus in the stool, lasting for more than two weeks
- Stools narrower than usual or a feeling that the bowel is not emptying completely
- Change in your bowel pattern
- Unexplained weight loss
If you notice any one of these symptoms, talk to your doctor.
You may also notice
- Bloating, abdominal fullness, general stomach discomfort that comes and goes or persists
- Unusual and prolonged fatigue
