That indication is based on outdated research that did not take into account the proven risk factors of cervical cancer. The American Cancer Society (ACS) does not even list the circumcision status of a woman's sexual partner as a risk factor for cervical cancer.
The ACS lists the following risk factors for cervical cancer: (1) age, (2) race and ethnicity, (3) human papillomavirus (HPV) infection, (4) smoking, (5) HIV infection, (6) diet, (7) oral contraceptives, and (8) low socioeconomic status.
"The most important risk factor for cervical cancer is infection by human papillomavirus."
"Certain types of sexual behavior increase a woman's risk of getting HPV infection. These high-risk sexual behaviors include intercourse at an early age, having many sexual partners, and having unprotected sex at any age."
