Symptoms of colorectal cancer

Sponsored Links

Symptoms of colorectal cancer vary depending on the location of the cancer within the colon or rectum. The most common presenting symptom is rectal bleeding.

Cancers from the left-side of the colon generally cause bleeding and in the late stages, cause abdominal pain, altered bowel habit and obstructive symptoms. In contrast, lesions arising from the right- side may produce vague abdominal pain and are unlikely to present with obstruction or altered bowel habit.

Other associated symptoms of colorectal cancer include

  • Generalized weakness,
  • Loss of appetite,
  • Weight loss and
  • Anemia resulting from chronic blood loss.
