Why is Prostate Cancer Screening Important?
the prostate cancer is detected early, the possibility of cure is high.
Prostate cancer is normally diagnosed when the patient on observing the
symptoms of prostate cancer approaches the Doctor. Prostate Cancer screening
is done for all men above 50 and at the age of 45 for those having predisposing
Fine Needle Aspiration is a quick and painless procedure for obtaining a prostate cell for cytologic examination. Tissues are taken out surgically through transurethral resection of the prostate/transrectal needle biopsy or prostatectomy, and histological examination of the tissues confirms whether the man has prostate cancer. PSA level which is in direct proportion with the total prostatic mass- is measured by a routine blood test. PSA indicates presence of the prostate tissue but it does not necessarily indicate malignancy.
Therefore, PSA testing is done along with direct rectal examination, which is a better option to conclude prostate cancer. After carrying out these screening tests, transrectal ultrasound (TURS) will be indicated for men once, PSA levels are elevated and direct rectal examination shows abnormalities.
Other tests to detect prostate cancer include skeletal x-ray to identify bone metastases, bone scans to detect metastatic bone disease, excretory urography detecting changes caused by urethral obstruction, renal function test, CT scan and lymphangiography to identify metastasis in the pelvic lymph nodes.
a radio labeled monoclonal antibody Capromab Pendetide with Indium-111,
is an antibody that is attracted to the prostate-specific membrane found
on the prostate cancer cells. On scanning, this radioactive element attached
to the antibody is noticeable, and this leads to detection of cancer spread.
For men above 50, the cancer screening as a second level of prevention
is suggested to decrease the risk of late detection.
