Prostate cancer is a form of cancer that develops inside the prostate gland. Prostate cancer is found to be the one of leading organs of cancer in large Indian cities such as Chennai, Delhi, Kolkatta, Bangalore and Mumbai. These cells can be benign (non cancerous) or cancerous. If the cells are non cancerous, they don’t cause any threat to life of the person. Such cells once removed usually don’t return / grow back.
