Seminal vesicles and the prostate are integral parts of the reproductive system in men. The prostrate usually weighs one ounce. Seminal vesicles are comparatively smaller glands present on different sides of the prostate. Prostrate plays a vital role in producing the fluid for semen—the fluid present in the prostate transfers to the urethra in the process of ejaculation. On the occurrence of prostate cancer, the cells start spreading and growing in number. Prostate Cancer originates when cancer cells rapidly start multiplying in the body. Prostrate, in a nutshell, is a distinctively minute walnut-shaped gland located in the pelvis of the males. Situated in the bladder, Prostate Cancer can be detected through a digital rectal exam. This cancer is the second most effective cause of death in men. Prostate carcinoma cells usually start spreading after the prostate tumor breaks. They move from the blood vessels to other parts of the body, like lymph nodes. Furthermore, the cancer cells attach themselves to the tissues and develop into new tumors. Usually, the Prostate Cancer cells spread to the seminal vesicles.
