Prostate cancer occurs when the cells of the prostate grow at an uncontrollable rate. Prostate cancer can either be slow-growing, then it does not become a serious threat for the health. On the other hand, others are fast-growing and aggressive forms and they can be harmful to the health.
Symptoms of prostate cancer include a need to urinate frequently, especially at night, difficulty starting urination or holding back urine, weak or interrupted flow of urine, painful or burning urination, difficulty in having an erection, painful ejaculation, blood in urine or semen and frequent pain or stiffness in the lower back, hips or upper thighs.
The causes of prostate cancer are still mysterious. The risk of prostate cancer increases steadily with age. Genes may also play an important role. A high fat diet can also increase the risk of getting prostate cancer.
Prostate cancer treatment consists in various options. Men affected by this type of cancer can choose between active surveillance, prostatectomy, radiation therapy, hormone therapy and chemotherapy.
Prostate cancer treatment side effects include urinary dysfunction, bowel dysfunction, erectile dysfunction, loss of fertility, effects due to the loss of testosterone and side effects of chemotherapy.
