rectal cancer symptoms in tamil

Rectal cancer develops usually over years; its actual cause is not known, but risk factors include increasing age (over 50), smoking, family history, high-fat diet, or a history of polyps or colorectal cancer or inflammatory bowel disease.

The major symptom of rectal cancer is bleeding from the rectum; other symptoms include anemia, fatigue, shortness of breath, dizziness and/or a fast heartbeat, bowel obstruction, small diameter stools, and weight loss.

For diagnosis, exams and tests may include fecal occult blood testing, endoscopy, digital rectal examination, sigmoidoscopy, CT/MRI imaging studies, along with routine blood tests and detection of carcinoembryonic antigen (CEA).
