Cancer of the prostate.

Prostate cancer presents a growing health problem in Western societies as longevity increases. It is characteristically a disease of elderly men associated with the development of osteoblastic bone metastases and initial hormone responsiveness to androgen deprivation. Previously regarded as a Cinderella of cancers, there is currently more controversy concerning the detection and management of both localised and metastatic disease than for any other common malignancy. A balance needs to be drawn between the potential gains of more aggressive management and the disadvantages in terms of increased treatment side effects and cost, taking into account both the natural course of the disease and the life expectancy of patients.
