Yes. We think most colon cancers evolve from benign polyps of the lining of the colon. I personally view it as a largely preventable disease, as these polyps are easily removed on colonoscopy before they become cancers. Trick is to get people to do colonoscopy. Read more...
Yes. The majority of colon cancers arise in colon polyps, which are among the most common specimens that we pathologists see. There are a variety of types, most with some propensity to turn cancerous. Especially, folks with lynch's hnpcc are prone to get colorectal cancer without polyps. Talk about colonoscopy with your physician -- saves lots of lives. Read more...

Please answer! What kind of meat should I eat to avoid colon cancer?

Not the answer. Some other folks here may disagree, but my reading of the good studies from the last two decades suggests to me that there's little connection between diet and colon cancer.

Only one type. Adenocarcinoma of the colon, or colon cancer as it is commonly known, is generally of one type but is often characterized by its location in the colon, and the stage (localized, spread to the outside of the colon, to the lymph nodes, or to other organs}. Read more...
Can be several. Although adenocarcinoma is the primary type of colon cancer, one can also get lymphomas, melanomas, smooth muscle tumors of the colon, and carcinoids, to mention a few. Read more...

What are the different signs of colon cancer?

They can vary. In older patients, physicians presume that "rectal bleeding is colon cancer until proven otherwise". Worrisome signs can include pain, diarrhea, constipation, blockage of the intestine, weakness, fatigue, weight loss, and even an enlarging lump that can be felt under the skin. These signs don't necessarily mean that one has colon cancer. The goal is to find colon cancer before any signs appear. Read more...

What are the different methods to detect colon cancer?

Several. Digital rectal exam, imunoassay for blood in the stool, lower GI barium enemas, colonoscopy, virtual or ct colonography, sigmoidoscopy. The best test at this time in my opinion is a colonoscopy properly performed with a proper bowel prep as it can be both diagnostic and therapeutic if the cancer is in a polyp that can be removed at the time of colonoscopy. Read more...
Multiple. Colonoscopy with biopsy is the most sensitive and specific. Other methods include flexible sigmoidoscopy, double contrast barium enema, and ct colonography (also called "virtual colonoscopy"). There are some stool tests that can serve as early detection methods, but still require one of the above tests to confirm. Talk with your doctor to find out which is the best for you. Read more...

How do you determine the different stages of colon cancer what's the prognosis?

See below. Colon cancer stage depends on how deep the cancer invades through the intestinal layers, if the cancer spread to lymph nodes, or if the cancer spread to other organs. Pathology helps determine the stage after surgical removal. Stage 1 best over 90% survival, stage 2 about 80% survival, stage 3 about 60% survival & stage 4 about 40% survival. Numbers very rough and each person responds differently. Read more...
