Cause and Signs of Colon Cancer in Men and Women

Cause and Signs of Colon Cancer in Men and Women

The Colon is part of the large intestine. The condition may be symptom-less in its early stages. Commonly through the tumor causes bleeding of the gut wall, leading to anemia and traces of blood in the feces. It may partially obstruct the colon affecting bowel movements, causing diarrhea or constipation. Early diagnosis would therefore include being observant for these signs. The presence of the tumor can be revealed by means of a barium meal, which shows up an obstruction if the gut is X-rayed. Alternatively internal examination by endoscopy can be performed. The tumor can be removed and the two ends of the gut sewn together again.

There is growing evidence that diets relatively high in fat and meat may be associated with a higher occurrence of colon cancer, as well as some other forms of cancer. Reducing consumption of fatty foods and meat, and frequently eating fresh fruits and vegetables, and cereals with a high fibre content, can help to reduce the risk.There are also a genetic predisposition in some people. These people may be identifiable in future by genetic screening techniques and be able to take specific precautions, particularly regular check-ups.

 Cancer is a group of diseases characterize by out-of-control cell growth and colon cancer forms when this uncontrolled cell growth initiates with cells in the large intestine. Most colon cancers start off from small, noncancerous (benign) tumors called adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps may develop into malignant colon cancers over time if they are not removed during colonoscopy. Colon cancer cells will attack and damage healthy tissue that is near the tumor causing many complications.

After malignant tumors form, the cancerous cells may travel through the blood and lymph systems, spreading to other parts of the body. These cancer cells can grow in several places, invading and destroying other healthy tissues throughout the body. This process itself is called metastasis, and the result is a more serious condition that is very difficult to treat.
