Step-by-step explanation:
Prostate cancer, also known as carcinoma of the prostate, is a tumor that develops in the prostate gland of the male reproductive system. It is the most common type of cancer in men. Prostate cancer occurs when glandular cells in the prostate mutate into tumor cells and can invade nearby structures or metastasize to other organs through the bloodstream or lymphatic system. Diagnosis involves a medical history, blood test, and rectal exam, with confirmation through biopsy of the cells. Treatment options include surgery, chemotherapy, and radiation therapy, with potential side effects such as erectile dysfunction and urinary incontinence.
