Dr. Akram Ismail — Colon Cancer
Colon cancer is one of the leading causes of deaths in developed countries. Hundreds of thousands of people die every year from colon cancer. It is a preventable disease. Rare cases of colon cancer are caused by inherited disease but in the majority of people, it starts as benign tumor that grows in the colon as we get older. As time goes by, these benign tumors turn malignant and eventually spread and cause death.
The benign tumors of the colon are called polyps. Colon polyps cause no symptoms. That is why there is no early warning signs for colon cancer. As the benign tumors turn malignant they start causing signs. The most common early sign of colon cancer is bleeding. Most of the time the bleeding is very little that can’t be seen or noticed except by specific tests. That slow gut bleeding eventually cause anemia and low iron level in the blood. Therefore the most common cause of iron deficiency anemia in elderly men and non menstruating elderly women is colon cancer. Some of the symptoms of colon tumors include change of bowel habits, progressive constipation, rectal bleeding and abdominal pain. Typically the systems appear in advanced cases. The most efficient tool in dealing with colon cancer is prevention. Colonoscopy is the gold standard in preventing colon cancer. This is simply by early detection and removal of polyps. When the polys are removed, the risk of colon cancer developing in these polyps is gone. There are other less optimal diagnostic tools including radiology and stools genetic tests.
