  Description
Colon cancer, also called colorectal cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix. The colon makes up the majority of the large intestine, and among other functions, helps rid the body of waste in the form of stool. The last inches of the large intestine are the rectum and the anal canal.

Colon cancer symptoms usually do not appear until the disease has progressed into an advanced stage. However, cancer screening can detect colon cancer in the early stages, before symptoms begin to appear. The size of the stool gives a good insight to what may be going on. Thin or ribbon-like stools can indicate that something is blocking the passage of stool, like a tumor.

In the colon, colorectal cancers arise from mushroom-shaped growths called adenomatous polyps. They are usually benign, but some develop into cancer over time.
  Diagnosis
After a physical exam, doctors may recommend the following tests to confirm the disease:
- Colonoscopy.
- Ultrasounds.
- Biopsy (sample obtained from colonoscopy).
- Angiography (barium contrast X - ray).
- Blood tests.
- Magnetic Resonance Imaging (MRI).
- Computed Tomography (CT or CAT).
- Positron Emission Tomography (PET).
