The curves for death rates from prostatic cancer and gonorrhea incidence rates in Denmark, over a span of thirty years, matched well with a lag period of forty five years. Moreover, a retrospective study conducted in the United States involving 75 cancer patients and 75 age-matched controls demonstrated a statistically significant association between gonorrheal infection and subsequent development of prostatic carcinoma. Two postulates are presented: the viral-venereal and the chronic infection theories. The recent increase in incidence of prostatic cancer in the United States could be the beginning of an epidemic in which astronomically high rates may be reached.
