Changing Face of Colorectal (Bowel) Cancer

Colorectal cancer is cancer affecting the large intestine and rectum. There has been a rapid increase in colorectal cancer in India, and this can be attributed to two factors:
Increasing life expectancyr
Following the western lifestyler
Most cases occur above the age of 50. It is true that if detected early, then colorectal cancer can be cured.

How does colorectal cancer develop?
Contrary to belief, it takes years to develop colorectal cancer. It develops from the inner lining of the bowel (mucosa). Initially, it forms a polyp, which over time turns into cancer. The tumour then starts to invade through different layers of the bowel wall and into the lymph nodes near it. If undetected, it can eventually spread to different parts of the body.

Can polyp be treated?
Yes. Most polyps do not contain cancer cells. Removal of polyp will be sufficient to prevent the cancer from developing.

In some cases, even after removing the polyp, cancer cells may be found. If the cancer cells have spread to the colon, then further surgery is advised if necessary.
