Prostate cancer is the leading cancer among American men, but little is actually known about its causes or risk factors. Androgens -- male sex hormones -- are necessary for the growth and functioning of the prostate gland and contribute to the growth of tumors of the prostate. Androgens are also necessary for the growth and development of hair. A new study expands on this association and reports that men with prostate cancer are more than twice as likely to have had male pattern baldness beginning at age 20 than men without prostate cancer.
