Prostate Specific Antigen (PSA): A blog about what PSA is and what it measures along with other cancer risk factors.

PSA is a cancer tumor marker. It is mainly used to help detect prostate cancer. PSA levels that are higher than normal can be an indication of prostate cancer or other conditions that cause inflammation of the prostate.

Tumor markers like PSA are used to detect cancer before signs and symptoms appear. The most common use of PSA testing is to screen men for prostate cancer after age 50, although it can also be used in younger men who may have a high risk for prostate cancer due to their family history or ethnicity.

Treatment decisions often depend on the results of the PSA test, but not always. Other factors, including a biopsy, may need to be considered as well, depending on your particular situation.

Prostate Specific Antigen (PSA) is not a test for prostate cancer. It is a test that measures the level of PSA in a sample of your blood. PSA is also known as a Prostate Specific Antigen test or PSA Test or just PSAT.

PSA is an antigen that is produced by normal, healthy cells in the prostate. An antigen is a substance which the body’s immune system makes antibodies against and views as foreign (called an ‘antigen’). Prostate cancer cells create more PSA than normal cells. So, when a man has prostate cancer, there will be more PSA in his blood than when he does not have any cancer. So, by testing for high levels of PSA in the blood, doctors can see if there is something wrong with a man’s prostate – and if there may be something wrong with his health.

1 out of 6 men who are over 50 years old will develop prostate cancer. Most of them will never know they have it because they do not have symptoms and their cancers are small and slow growing.*

PSA tests are used to detect prostate cancer in men before they experience any symptoms (such as trouble urinating or pain in the groin). They can also help doctors find out how

Prostate Specific Antigen (PSA) is a protein produced by normal cells of the prostate gland. It is normally found in the blood, and a high level of PSA in the blood may be an indication of cancer or other prostate problems.

Tumors of the prostate produce more PSA than normal cells. If a man has an abnormally high PSA measurement, it may indicate that he has cancerous tissue in the prostate. However, a number of conditions besides cancer can cause an elevated PSA level. The fact that a man has an elevated PSA does not necessarily mean that he has or will get prostate cancer. The value of PSA testing is controversial because different men with the same value may have very different probabilities of having prostate cancer and may require different actions as a result.

Considering that PSA is not a cancer test, why is it used as one? There are several reasons why PSA is used to screen for prostate cancer.

One of the most important reasons why PSA is used as a prostate cancer screening tool is that it can be measured easily and inexpensively. The PSA test can be performed in a doctor’s office or clinic without the need for sophisticated equipment. In addition, the PSA test costs less than $50 and takes only about five minutes to complete.

What are the limitations of a PSA test? The main limitation of PSA testing is its inability to distinguish between prostate cancer and other conditions such as benign enlargement of the prostate, prostatitis, bacterial infections and tumors that are located outside of the prostate gland. In addition, some men with prostate cancer do not have raised levels of PSA in their blood (a condition called “PSA-undetectable” or “PSA-naive”). If a man with known prostate cancer has no PSA in his blood, this may falsely reassure him that he does not have disease; however, if he later develops elevated levels of PSA in his blood stream he will not receive an early warning signal.**

Prostate specific antigen (PSA) is a protein that is produced in the prostate gland. PSA levels are typically elevated in men with prostate cancer and lower than normal in men without prostate cancer.

The PSA test is used to help detect prostate cancer. It may be used alone or with other tests such as digital rectal exam (DRE). Prostate cancer is one of the most common cancers in men, but the majority of cancers detected on the basis of PSA tests are not life-threatening. The PSA test has limitations and false positives can occur, which means that some men with elevated PSA levels do not have prostate cancer.

PSA is a protein produced by cells in the prostate gland. It is released into the blood stream and can be used to measure the health of the prostate gland. PSA levels are usually tested to screen for prostate cancer, although there are other conditions that can cause an elevated PSA level.

The test does not diagnose a cancer and should not be used to make that call. The test is for screening purposes only. It can also catch other conditions that may be present such as an infection or inflammation of the prostate, or prostatitis. Thus, an elevated PSA level is not always a sign of cancer. However, it can be a marker that something needs further investigation.

PSA is a protein produced by cells of the prostate. PSA levels can be measured in blood and used to screen for prostate cancer.

PSA is made by the prostate gland, which is located below a man’s bladder and surrounds the urethra. The prostate gland makes some PSA all the time. Small amounts of PSA are released into the blood every day. Some PSA also leaks out of the prostate every time a man has a climax (orgasm). The amount of PSA in a man’s blood seems to be directly related to how much PSA his prostate gland makes.

The role of PSA in screening for cancer:

PSA testing cannot tell whether or not a man has cancer. But it can find out if there is something wrong with his prostate that might lead to cancer later on. It is not yet known whether finding out about it sooner helps men live longer or feel better. (To understand more about risk factors, click here.)

Because many things affect PSA levels, a single PSA test result may not tell you very much about your chance of having cancer. So it is important to have your doctor check your results over time. If you keep getting higher-than-normal readings, this may mean you have
