Prostate cancer is cancer that occurs in a man's prostate which is a small walnut-shaped gland that produces the seminal fluid that nourishes and transports sperm. It usually grows slowly and initially remains confined to the prostate gland, where it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly.
Pathopysiology: Prostatic intraepithelial neoplasia (PIN) is the histologic entity widely considered to be the most likely precursor of invasive prostate cancer. Although not all patients with high-grade PIN (HGPIN) progress to develop invasive disease. It is characterized by cellular proliferation within pre-existing ducts and glands, with cytologic changes that mimic those of cancer. PIN is associated with progressive abnormalities of phenotype and genotype that are intermediate between normal prostatic epithelium and cancer.
Treatment: Hormone therapy will stop your body from producing the male hormone testosterone. Prostate cancer cells rely on testosterone to help them grow. Cutting off the supply of hormones may cause cancer cells to die or to grow more slowly. Surgery to remove the prostate Chemotherapy
