Abraham Leo Wolbarst

Abraham Leo Wolbarst, M.D. was solely responsible for the invention of the myth that circumcision rendered males immune to penile cancer.[1] Worldbarst wrote an article that was published in the Lancet in 1932, implicating human male smegma as carcinogenic.[2] Worlbarst's myth was based entirely on unverifiable anecdotes, ethnocentric stereotypes, a faulty understanding of human anatomy and physiology, a misunderstanding of the distinction between association and cause, and an unbridled missionary zeal, and it had absolutely no basis in valid scientific and epidemiological research.[3]

Wolbarst was directly responsible for its proliferation, and all subsequent repetions of this myth are directly traceable to Wolbarst's article, though Wolbarst himself advocated universal neonatal circumcision principally as a preventive for epilepsy, paralysis, and masturbation. Circumcision advocates such as Wolbarst do not seem to have promoted this myth because they have a genuine interest in reducing penile cancer; they used it instead as a scare tactic in the promotion of neonatal circumcision.[4]

Epidemiological studies disproved Wolbarst's myth long ago. In North America the rate of penile cancer has been estimated to be 1 in 100,000[5]. Maden et al reported penile cancer among a fifth of elderly patients from rural areas who had been circumcised neonatally and had been born at a time when the rate of neonatal circumcision was about 20% in rural populations.[6] Their study also shows that the rate of penile cancer among men circumcised neonatally has risen in the United States relative to the rise in the rate of neonatal circumcision.
