I need to know the main symptoms for prostate cancer thankyou?

Variable: Prostate cancer is very rare before 40 years of age. Usually there are no symptoms in early prostate cancer. There may be trouble urinating, blood in urine or bone pain due to metastases. See this site for more info. http://www.mayoclinic.com/health/prostate-cancer/ds00043/dsection=symptoms.

Mostly none: Since a simple blood test and rectal exam pick up most prostate cancers before they are large or involved enough to cause symptoms, most prostate cancers are diagnosed without any symptoms. Understand that while some prostate cancers can cause urinary symptoms, many other benign things can also cause urinary symptoms.. Medications, benign enlargement of the prostate, bladder issues.
