If a person has symptoms that might be caused by colorectal cancer, the doctor will want to get a complete medical history and do a physical examination. The doctor may also do certain tests to look for cancer. Many of these tests are the same as those done to screen for colorectal cancer in people without symptoms.
If you have symptoms of colorectal cancer or the results of your physical exam or blood tests suggest that colorectal cancer might be present, your doctor may recommend more diagnostic testing. Most often, this will be a colonoscopy, although other tests may be performed prior to your first colonoscopy.
A procedure in which tissue samples are removed from the body by a needle or during surgery for examination under a microscope to determine if cancer or other abnormal cells are present. There are many different types of biopsies.
A procedure that examines the rectum, the large intestine, and the lower part of the small intestine using a contrast dye containing barium.
Tests such as a CT scan, ultrasound, or MRI of the abdomen may be done to look for tumors or other problems. These tests may also be done if colorectal cancer has already been diagnosed to help determine the extent (stage) of the cancer.
