Does gender matter in colon cancer screening ?

Middle-aged men are twice as likely as women to end up with a cancer diagnosis after a colonoscopy, according to  study that challenges current screening guidelines. Currently, people at average risk of colon cancer start screening for the disease at age 50, regardless of gender. The study found that around 80 55-year-old men would need to undergo colonoscopies to spot one cancer, with the same true for 65-year-old women. The same logic held for the pre-cancerous growths called advanced adenomas, which doctors also look for during colonoscopies.

About one in 19 men develops colon cancer at some point and slightly fewer women do. The disease, which usually strikes older adults, is the third leading cause of cancer deaths. At 0.8 percent, the rate of colon cancer among men aged 50 to 54, for instance, was twice that found among women in the same age group. That means 125 men would need to have a colonscopy to find one tumor, versus 264 women. Read more…
