What is prostate cancer:
Before to talk about prostate cancer, we will explain what is prostate. The prostate is a gland in the male reproductive system that produces the majority of fluid that make up sperm. Gland in the size of a walnut, is located below the bladder and surrounds the upper part of the male urethra, the tube through which urine flows from the bladder. Prostate function is regulated by testosterone, a male sex hormone produced by the testicles. Although the disease is rare in men under 50 years, experts believe that most seniors have at least “traces” of prostate cancer. Forming tumor cells do not develop normally and they multiply and grow uncontrollably extending to other tissues. Prostate cancer is usually a slow-growing tumor, often not giving symptoms until advanced stages. Although the disease tends to progress slowly in general is deadly if the tumor grows beyond the gland.
How prostate cancer occurs?
Prostate cancer affects mainly older men. Four out of five cases are diagnosed in men older than 65 years and less than 1% were aged under 50 years. Although rare, prostate cancer can be found and in patients of 30-40 years. Men who have a family history of prostate cancer are at higher risk of disease than general population. Hidden factor linking the diet to prostate cancer is probably hormonal prostate cancer. Fat stimulates an increased production of testosterone and other hormones and testosterone stimulates tumor growth. In fact, researchers know more about what does not cause prostate cancer than what determine it.
Prostate cancer symptoms:
There are no warning signs and symptoms of early stage prostate cancer, but the following symptoms may occur: the need to urinate frequently, especially at night; difficulty in starting and stopping urine flow; a weak or interrupted urinary stream; a painful or burning sensation during urination or ejaculation; blood in urine or sperm.
How prostate cancer is diagnosed:
Two initial tests are commonly used to diagnose prostate cancer in the absence of symptoms. One is the digital rectal examination, the doctor palpates the prostate through rectum to find out if there are endured or uneven signs known as nodules. The other test is a blood test used to detect a substance secreted by the prostate called prostate specific antigen (PSA). When used together, these tests can detect abnormalities that may suggest the presence of prostate cancer. The diagnosis can only be confirmed by microscopic examination of prostate cells. This biopsy is done at the office of Urology. A small piece of tissue is taken from the prostate and examined under a microscope.
