10 or more sexual partners doubles cancer risk for women
The risk in men with the same number of partners is not as high more, study reports
People who have had 10 or more sexual partners during their lifetime may have increased odds of being diagnosed with cancer, a study suggests.
Women, in particular, have nearly twice the risk when they have had 10 or more past partners compared with when they had one or none, researchers report in BMJ Sexual and Reproductive Health.
