The treatment of organ-confined prostate cancer has involved cutting out, radiating, or freezing the gland to try to cure the disease. In more advanced cases, the goal has been to control the cancer for at least some time by using endocrine treatment or chemotherapy. Earlier diagnosis and improved treatment techniques in recent years have certainly led to better results. Interestingly, however, early diagnosis of prostate cancer, and/or early treatment of prostate cancer has not improved the prostate cancer specific survival or overall survival from prostate cancer.
The key to curing prostate cancer, however, ultimately will come from an understanding of the genetic basis of this disease. Genes, which are chemical compounds located on the chromosomes, determine the characteristics of individuals. Accordingly, investigators at research centers have focused on identifying and isolating the gene, or genes, responsible for prostate cancer. Studies have uncovered some of the genetic links to the disease. Now studies will be performed to try to block, or modify, the offending genes to prevent or alter the disease. Finally, vaccines to either prevent or treat prostate cancer have been developed and are in use.
There are no warning signs of early prostate cancer. Once a tumor causes the prostate gland to swell, or once cancer spreads beyond the prostate, the following symptoms may happen:
A frequent need to urinate, especially at night
Difficulty starting or stopping a stream of urine
A weak or interrupted urinary stream
Leaking of urine when laughing or coughing
Inability to urinate standing up
A painful or burning sensation during urination or ejaculation
Blood in urine or semen
