- Colon CancerColon cancer affects 134,000 people per year in the United States and causes the death of 55,000 patients per year. This makes colon cancer the #2 cancer killer in the United States. Almost all colon cancers start out as a polyp on the inside wall (lumen) of the colon. Polyps start out as small wart-like bumps the size of an unground peppercorn.
- EndoscopyEGD (also known as upper GI endoscopy or panendoscopy) is a procedure that enables your physician to examine the lining of the upper part of your gastrointestinal tract, i.e., the esophagus (swallowing tube), stomach and duodenum (first portion of the small intestine) using a thin flexible tube with its own video camera and light source. EGD is usually performed to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting or difficulty swallowing. It is also the best for finding the cause of bleeding from the upper gastrointestinal tract. EGD is more accurate than x-ray films for detecting inflammation, ulcers or tumors of the esophagus, stomach and duodenum. Upper endoscopy can detect early cancer and can distinguish between benign and malignant (cancerous) conditions when biopsies (small tissue samples) of suspicious areas are obtained.
