Why is the PSA test controversial?
Check It Today !Using the PSA test to screen men for prostate cancer is controversial because it is not yet known if the process actually saves lives.

Frequently Asked QuestionsA: PSA stands for prostate specific antigen. It is a protein that is produced by normal prostatic cells as well as cancerous prostate cells and is measured with a blood test. In many instances, especially in men where there is a family history of the disease, the higher the PSA, the greater the chances of prostate cancer. If the PSA is "too high" a prostate biopsy may be recommended. Defining what is "too high" depends on age as well as prostate size and previous PSA readings.
Related QuestionsPatients - Product InformationThe PSA or prostate specific antigen test is a blood test used to measure the amount of a particular protein found in a person's blood. Prostate cells make this protein and normally the PSA level is usually low (less than 4.0 nanograms per milliliter). Prostate cancer and certain other conditions can raise the PSA value because of an increase in the amount of prostate specific protein circulating in the blood. If the PSA value is higher than 4.Related Questions
URF - The Site for Prostate Cancer InformationThe PSA blood test is probably the single most accurate test we have for the detection of prostate cancer. PSA is a protein that’s produced in the prostate gland. Normally, the PSA should be very low in the bloodstream. Our studies showed that the median PSA level is 0.7 for men in their 40s, 0.9 for men in their 50s and 1.4 for men in their 60s. If the prostate is diseased – from benign enlargement, inflammation, or prostate cancer – the PSA is elevated.Related Questions

Check It Today !PSA test results report the level of PSA detected in the blood. The PSA level that is considered normal for an average man ranges from 0 to 4 nanograms per milliliter (ng/ml). A PSA level of 4 to 10 ng/ml is considered slightly elevated; levels between 10 and 20 ng/ml are considered moderately elevated; and anything above that is considered highly elevated. various factors can cause PSA levels to fluctuate, one abnormal PSA test does not necessarily indicate a need for other diagnostic tests.
Related QuestionsWhat are some of the limitations of the PSA test?
Check It Today !Detection does not always mean saving lives: Even though the PSA test can detect small tumors, finding a small tumor does not necessarily reduce a man's chance of dying from prostate cancer. PSA testing may identify very slow-growing tumors that are unlikely to threaten a man's life. Also, PSA testing may not help a man with a fast-growing or aggressive cancer that has already spread to other parts of his body before being detected.
