Women who drink alcohol may have an increased risk of persistent infection with the human papillomavirus (HPV), according to researchers in Korea. Some varieties of the virus have the potential to cause cervical abnormalities that can lead to cancer.
Most cases of HPV disappear on their own, but in some cases the infection persists, Yahoo Health reports. The virus is sexually transmitted.
The Korean researchers tested 9,230 women for HPV and asked them about their alcohol intake. They found women who drank alcohol were almost three times more likely than non-drinkers to test positive for HPV at the beginning of the study, and again after two years.
