Cancer of the prostate is one of the most common cancers among men. It is a disease noted for its secondary symptoms. It is usually detected because a physician begins analyzing symptoms that could suggest other disorders. There may for example, be blood in the urine, indicating a serious problem that could be located anywhere along the urinary tract. Because the prostate encircles the urethra, which is the outlet from the bladder, any prostatic problem can cause disturbances in the normal passage of urine, including increased frequency of urination or discomfort in urinating. however, these also could be the symptoms of ailments other than cancer of the prostate.
Diagnosis of prostatic cancer usually begins with an examination of the prostate through the wall of the rectum. If during the examination of prostate for men over the age of 40, the physician feels a lump or hardened area, further tests are ordered. The presence of a lump in the prostate need not be evidence of cancer; about half of the lumps and nodules are caused bt fibrosis, calcium deposits, or other noncancerous bodies. Transrectal ultrasound is a newer detection method used in conjunction with the traditional digital rectal examination by a cystoscope, which is inserted through the urethra to provide a view of the tissues of the area, plus a laboratory examination of tissue samples and prostatic fluid samples. A microscopic study of the samples may reveal the presence of cancer cells. In the search for evidence of cancer of the prostate, diagnostic clues may be found in blood chemistry tests and by the examination of a urinary pyelogram that could indicate obstractions from the prostate walls.
