"We have known since 1935 with the publication of Arnold Rich's autopsy study that there is a large pool of latent, clinically insignificant prostate cancer in the male population which increases with age. By the age of fifty, 30-40 per cent of males will harbor a clinically insignificant focus of prostate cancer. The vast majority succumb to old age before the prostate cancer bothers them. These prostate cancers are the incidental findings at post mortem exam...
...Prostate cancer is a slow growing indolent disease with a 99 per cent 5 year survival after diagnosis. The incidence of latent prostate cancer is estimated to be one half of the male population 65 and over (7 million of the 14 million males), yet there are only 30,000 deaths per year. This means the average male has a 0.5% chance of dying from prostate cancer, (or a 99.5 chance of dying from other causes, not prostate cancer).
PSA screening programs send the screened patients to trans-rectal ultrasound guided biopsy which finds these latent prostate cancers, many of which should not be treated. Mainstream conventional treatment involves radical prostatectomy, radiation therapy, or hormonal castration. The first two are associated with adverse effects of incontinence, and Erectile Dysfunction . Treatment with androgen blockade, (a form of chemical castration) is associated with increased mortality and osteoporosis."
