Five min test to detect bowel cancer

In what could be called a major breakthrough, scientists claim to have developed a “screening test” which takes just five minutes to detect bowel cancer and also reduces the risk of developing the disease substantially.

The new test, which involves the quick removal of growths with the potential to turn cancerous, has been devised following a 16-year-old study, ‘The Lancet’ reported.

The study of more than 170,000 volunteers aged between 55 and 64 suggested that the examination of the lower colon and rectum reduced deaths by 43 per cent.

In the study group examined, incidence of bowel cancer fell by a third. A quarter of the volunteers in the study underwent a sigmoidoscopy, where a camera mounted on a thin, flexible tube, known as a FlexiScope, was inserted about a third of the way into the bowel.

According to the scientists, most bowel cancers stem from polyps or symptomless growths in the rectum and colon and where these were found, they were removed in a safe and pain- free procedure.

“Our study shows for the first time that we could dramatically reduce incidence of bowel cancer and the number of people dying from the disease by using this one-off test. “No other bowel cancer screening technique has ever been shown to prevent the disease,” ‘The Times’ quoted Wendy Atkin of Imperial College London, who led the study, as saying.

Colorectal Cancer Overview

Colorectal cancer: what is it?colorectal-cancer-overview
Colorectal cancer ranks third in the most common cancers , especially among men than among women. A man of 14 and 16 women are likely to have colorectal cancer in their lifetime.As its name suggests, this type of cancer evelops in the colon or rectum, the last part of  the large intestine.
Colorectal cancer is much more common in industrialized countries. Lifestyle, especially diet, play a role in its onset. This explains, for example, that the Japanese, little affected by colorectal cancer in Japan, becoming as much as their fellow Americans a few years after having emigrated to the United States and adopted their diet.
Some people can contract due to a hereditary predisposition. But in 75% of cases, no such predisposition is present.

Evolution
Colorectal cancer takes several years to form, as the majority of cancers. He usually does from polyps in the lining of the large intestine. The polyps are small fleshy growths.
There are several kinds. Most often they are mild. However, we know that some may become cancerous. It takes on average 10 years for a polyp to form a cancerous tumor. [click to continue…]
