New test can spot cancer risk and save 3,000 lives a year

A screening test that takes five minutes and cuts the risk of developing bowel cancer by a third could save at least 3,000 lives a year, research has shown.
A 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. The test, which involves the quick removal of growths with the potential to tu
cancerous, is seen as a strategy that could transform prevention and early detection of the disease. In the study group examined, incidence of bowel cancer fell by a third.
Scientists said yesterday that the research, published on The Lancet website, made the national introduction of the one-off test for all men and women at the age of 55 a “no brainer”.
A quarter of the volunteers in the 16-year study underwent a sigmoidoscopy, where a camera mounted on a thin, flexible tube known as a Flexi-Scope was inserted about a third of the way into the bowel. 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, the researchers said.
Researchers also said that the test could save thousands of lives every year. Bowel cancer is the third most common cancer in Britain and the second biggest cancer killer.
The present screening method, called the faecal occult blood test, shows any traces of blood in stools and helps to detect the cancer at an early stage. This test, which has been extended to people over 60, would continue as it can identify cancers farther up the bowel.
Harpal Kumar, chief executive of Cancer Research UK, described the study, which started in 1994 and is the largest and longest running of its kind, as “one of those rare occasions to use the word ‘breakthrough’ ”.
He called for the next gove
ment to add the test to the bowel cancer screening...
