In 1935, Dr Arnold Rice Rich, pathologist, wrote the following:
For a number of years the writer has been impressed by the frequency of the small carcinomas that have been found in the prostate in the routine autopsy material of this department (Department of Pathology, John's Hopkins Medical School, Maryland, USA).1
The background of this observation was an investigation of the incidence of prostate cancer in a series of 2000 autopsy cases. Of these cases, 292 were male, aged 50 years or older. The prostates of these 292 males were investigated routinely macroscopically and microscopically with one block taken from each prostate. The blocks were taken at palpable lesions or randomly if no obvious macroscopic lesion could be found. Although this procedure is nowhere near today's serial sections of the specimens from radical prostatectomies, Dr Rice Rich found primary prostate cancer in 41 (14%) of the 292 specimens. In 14
