A new study suggests men should have their first colonoscopy before age 50, the currently recommended age, while women can wait longer, according to a Journal of the American Medical Association report.
The Austria-based study in JAMA found that men frequently have advanced polyps that could lead to colorectal cancer at ages 45-49, a decade earlier than women.
In the study, 18.5 percent of men aged 50-54 had adenomas, compared with 10.7 percent of women those ages.
