7 Boczko et al . found numerous reports of penile cancer in circumcised men, thus conclusively disproving Wolbarst's false claims of protection from penile cancer by circumcision. No such difference is found. None of these differences is statistically significant. Further, within the same time frame, both France and the United States had the same rate, 0.3, of deaths due to penile cancer. Hellberg et al .
Cervical cancer has epidemiologic similarities to venereal disease.
The human papilloma virus is spread by sexual contact. 18 DNA sequences from HPV have been identified in 50 percent of cervical cancers tested. In circumcised men, the cancer usually occurs along the line of the circumcision scar. It is thus categorically not true that circumcision eliminates the risk of penile cancer, although that assertion has been made nonchalantly in a number of papers by Schoen, Wiswell, and Weiss. It strikes mostly older men.
