Colon cancer symptoms

Somali: Kaansarta mindhicirka iyo malawadka: Waxa la rabo inaad ogaatid

Spanish: Cáncer colorectal: Síntomas

Certain symptoms may be the result of colon cancer.

Colon cancer signs may include:

  • rectal bleeding
  • bloody or tarry stools
  • stools that are narrower than usual
  • pain during bowel movements
  • constipation or diarrhea lasting more than one month
  • general stomach discomfort (bloating, fullness, cramps, gas pains) for a period of time
  • a feeling that the bowel does not empty completely
  • weight loss for no reason
  • constant tiredness
  • vomiting
  • low hemoglobin

However, it should be noted that colon cancer may not have any symptoms.

Colon cancer symptoms can also be caused by other problems such as ulcers, an inflamed colon or hemorrhoids. If you develop any of these symptoms, see your health care provider.
