Prostate cancer is a disease where cancerous cells form in the prostate tissues. The prostate is a gland that is located in the male reproductive system that is found below the bladder and in front of the rectum. The prostate is about the size of a walnut and surrounds the tube that empties urine from the bladder called the urethra. The prostate gland produces fluid that makes up one of the elements of semen.
These cancer cells can spread from the prostate to more parts of the body, such as the bones and the lymph nodes. This type of cancer may cause urinating difficulty, a problem during sexual intercourse, erectile dysfunction, difficulty starting and stopping the urinary stream, burning sensation during urination, or blood in the urine or semen.
Prostate cancer seems to develop in older men, such as over fifty. Even though it is the most widespread type of cancer in men, some never have any symptoms, and never undergo any treatments for this and in the end die of some other causes. The reason for this is because this type of cancer is so slow growing and is free of symptoms which make up about two-thirds of the prostate cancer cases.
The PSA (prostate specific antigen) test is one of the most common tests but there is much dispute about its accuracy. Other ways that prostate cancer can be detected is by symptoms, physical examinations or biopsy. If prostate cancer is suspected after any of these mentioned above, then CT scan or bone scans will be performed.
How prostate cancer is treated depends on the stage of the cancer, the Gleason score, the patient’s general health and their age. Treatment of prostate cancer can range from keeping a watch on the cancer, to removing the entire prostate gland and/or radiation therapy.
The American Cancer society has estimated that about one in every six men will be diagnosed with prostate cancer during his lifetime but then only one in thirty-four men die with this cancer. Prostate cancer is responsible for more deaths than any cancer except lung cancer.
