British Screening Colon Cancer – The British government began a colon cancer screening program in 2006 for people over aged 60 to reduce deaths in England by a goal of 16%.
And as a result they are on track to reach that goal, according to researchers who conducted an analysis of the first 1 million test results.
The study also found that left-sided colon cancer was detected much more often than right-sided cancer, which is believed to be more aggressive. This finding suggests that different strategies may be needed to detect the disease on both sides of the body.
During the screening since it began researchers found that men as expected were more likely than women to have colon cancer. As a result of the screening program about 71 percent of the cancers were detected early.
It was thought that left-sided disease would account for 67 percent of the cancers detected by the screening program, while 24 percent would be right-sided. But the study found that about 77 percent of the cancers detected by the screening program were left-sided and 14 percent were right-sided.
“Different screening strategies may be required to effectively screen for right-sided bowel cancer,” concluded researchers led by Dr. Richard Logan of the University of Nottingham Medical School, in England.
The study appears in the Dec. 7 issue of the journal Gut.
Colorectal cancer is the third most commonly diagnosed cancer in the world, but it is more common in developed countries. Around 60% of cases were diagnosed in the developed world. GLOBOCAN estimated that, in 2008, 1.24 million new cases of colorectal cancer were clinically diagnosed, and that this type of cancer killed 610,000 people.
