Prostate cancer is the most common tumor in men. The American Cancer Society estimates that 220,800 men will be diagnosed with the disease in 2015.
According to standard medical theory, prostate cancer typically turns deadly after tumors stop responding to drugs that block the production of testosterone and its receptors.
Therefore, for years, urologists have treated prostate cancer by decimating a man’s testosterone levels, a treatment that is formally known as androgen deprivation therapy.
