A paper published BJU International, Vol. 100, Issue 1, pp 5-6 (April 2007). Three avid pro-circumcision advocates wrote a paper justifying male circumcision as a preventative against prostate cancer. The authors claim that lack of circumcision is a risk factor of prostate cancer.
Dr. Van Howe responded to the Morris paper in the BJU International, Vol. 100, Issue 5, pp. 1193-94 (2007). Dr. Van Howe identified faults and unsubstantiated assumptions in the original paper. He states, "The concept of using circumcision to reduce prostate cancer risk has no biological or epidemiological foundation. Even if one is willing to depart from reality and use the most extreme assumptions as put forth by Morris et al., circumcision of infants is not cost-effective."
