A new study from the University of British Columbia has found that having a partner with more sexual partners, including anal sex, has a greater impact on a woman’s risk of cervical cancer than the number of sexual partners she has.
In addition, women who have had anal sex are about 15 per cent more likely to develop cervical cancer.
“We found that anal sex is more likely in women who had multiple sexual partners and also in women with a history of pelvic inflammatory disease,” said Dr. Sarah McDonough, an associate professor in the Department of Obstetrics and Gynecology and an author of the study.
“In women who are infertile, the risk of developing cervical cancer is much lower.”
McDonought said the new findings support the findings of previous studies.
A study from Canada and Sweden found the risk for cervical cancer in women was lower in men who had more than four sexual partners compared to women who reported never having more than three. “
The fact that women with higher levels of sexual activity are more likely also to have cervical cancer suggests that there is something in their sexual behaviour that’s causing them to develop a higher risk.”
A study from Canada and Sweden found the risk for cervical cancer in women was lower in men who had more than four sexual partners compared to women who reported never having more than three.
Researchers at the University at Buffalo looked at the sexual behaviour of more than 4,000 Canadian women aged 18 to 59.
They found that women in their prime reproductive years who had had anal intercourse, oral sex and vaginal intercourse were three times more likely and women who never had anal or oral sex were seven times more common to develop ovarian cancer than women in similar age groups who had never had more sexual activity.
McDonight said she hopes other studies will look at whether anal sex can cause cervical cancer as well.
“Our findings suggest that sexual behaviour has an impact on the development of cervical carcinoma,” she said.
“And that is something that should be explored further, because the risk is greater for women who engage in sexual activity at an earlier age.”
The study is published online in the Canadian Journal of Obstetric and Gynecolics.
