Prostate cancer cells, coloured scanning electron micrograph (SEM). The prostate gland is a walnut sized gland at the base of the bladder and is found only in men. Prostate cancer can develop when the cells in the prostate start to divide and multiply in an uncontrolled manner. Prostate cancer often starts slowly and may never cause problems but some men have prostate cancer that is more likely to spread and is therefore more problematic. Statistically, currently 84% of men survive prostate cancer for 10 years or more. Magnification: x4000 when printed at 10cm wide.
