Abstract
Research has shown that prostate specific antigen (PSA) is a tumour marker for diagnosis of cancer prostate with significant prognostic value. Screening studies in North America and Europe have revealed that carcinoma prostate is common. Early detection and treatment improves the quality of life besides preventing deaths due to metastatic prostate cancer. Radical prostatectomy and laparoscopic radical prostatectomy has become the standard treatment for localized prostate cancer in all major uro-oncological centres resulting in reduced mortality. Magnetic resonance imaging and positron emission tomography have helped in detecting local and distant spread of cancer prostate. Revised approach to reduce occurrence of prostate cancer by the use of 5 alpha reductase inhibitors like finasteride and dietary supplements has been instituted. The World Health Organisation (WHO) has recommended lifestyle changes to promote men's health and reduce the incidence of prostate cancer.
