In its early stages, prostate cancer shows no signs. When detected by a doctor, signs of prostate cancer include abnormal results from a digital rectal exam, such as a suspicious lump, or a high result from a prostate-specific antigen blood test, according to WebMD. Symptoms are not from the cancer itself but arerather due to theblockage caused by a tumor in the prostateand include leaking urine, blood in urine and afrequent need to urinate.
When prostate cancer moves out of the prostate into other parts of the body and the prostate gland has become swollen, symptoms may include being unable to stand while urinating, bloody semen and urine, a burning feeling during ejaculation or urination, frequent urination, urine leaking when coughing or laughing and trouble stopping or starting the flow of urine.
In the advanced stages of prostate cancer, symptoms often include weight and appetite loss, constipationand paralysis or weakness of the lower extremities. Other symptoms include stiffness and strong dull pain in the upper thighs, ribs and lower back, bone pain, fatigue, nausea and vomiting, and swelling in the lower limbs.
Prostate cancer progresses very slowly, so many men have no symptoms until the later stages. Prostate cancer is found in its early stage about 85 percent of the time when chances of survival with treatment are very good.
