Studies in the epidemiology of prostatic cancer: expanded sampling.

摘要: Abstract From comparisons of prostatic cancer patients with matched control for selected risk variables, are characterized by three main trends: (a) delayed sexual drive and development, (b) early repression sexuality, (c) premature cessation sexuality. Excessive numbers reported occupational exposure to fertilizers auto exhaust fumes. Diets the were higher in animal fats. No differences found between both groups frequencies multiple marriages or sex partners, nor stressful effects from events late life. Trends circumcision other variables presented. The data suggest that hormonally conditioned, support a provisional endogenous rationale initiation cancer, oppose hypothesis favoring transmissible oncogenic agents. If results continue hold up increased sampling, limitation upon activity at any time life may increase risk.
