- The “normal” PSA serum concentration ranges between 1.0 and 4.0 ng/mL. However, since the prostate gland generally increases in size and produces more PSA with increasing age, it is normal to have lower levels in young men and higher levels in older men. The PSA level also depends on ethnicity and family history of prostate cancer. Other than the single reading, the changes in PSA numbers on an annual basis (also referred to as PSA-velocity) also play a role in decision making about the PSA marker.

Prostate-Specific Antigen (PSA) Test Most men with an elevated PSA level turn out not to have prostate cancer; only about 25 percent of men who have a prostate biopsy due to an elevated PSA level actually have prostate cancer (2). A false-negative test result occurs when a man’s PSA level is low even though he actually has prostate cancer.

Causes Of Elevated PSA: Symptoms And Treatment Of High PSA Levels The prostate specific antigen is often used as a biological marker or a tumor marker for detecting prostate cancer. However elevated levels of PSA are not indicative of prostate cancer and additional investigations are required for further diagnosis. There are several factors that may be responsible for elevated levels of PSA in the blood, 1  Benign Enlargement of the Prostate or BPH is a condition which affects older men.

5 Ways to Lower Your PSA Count While no man wants to have an abnormally high PSA count, whatever the cause, it's important to remember that the PSA count is an indicator of problems, not the cause of them. The best way to avoid a bad test score is to have a healthy prostate.

- Your “normal” PSA depends on your age, but even if your PSA level is elevated between 4 and 10, you have only about a 25 percent chance of prostate cancer. Here are some reasons, besides prostate cancer, that your PSA level could be above normal.

- What does PSA mean – Prostate Specific Antigen What is PSA? Prostate Specific Antigen PSA, is an enzyme found in the blood produced exclusively by prostate cells. Normal levels of PSA in the blood are small amounts between 0-2.5 ng/ml. Higher than normal levels, greater than 2.5 ng/ml, can be caused by cancer or benign, non-cancerous conditions such as enlarged prostate, prostate inflammation, infection, or trauma. All elevated readings of PSA should be checked.

- Men with low PSA (prostate-specific antigen) levels on screening tests can still have prostate cancer. Men with low PSA (prostate-specific antigen) levels on screening tests can still have prostate cancer, according to a recently released study.

PSA 1 The value for total PSA below which the presence of prostate cancer is considered to be unlikely is 4.0 ng/ml (nanograms per milliliter of blood). 2  There are some that feel that this level should be lowered to 2.5 ng/ml in order to detect more cases of prostate cancer.f the DRE is normal but the PSA is moderately elevated, a free PSA test may be used to look at the ratio of free to total PSA. This can help to distinguish between prostate cancer and other non-cancer causes of elevated PSA. Other tests may also be recommended if either the PSA or the DRE is found to be abnormal.

Slideshow: A Visual Guide to Prostate Cancer But there are many exceptions: 1  Men can have prostate cancer with a PSA less than 4. 2  A prostate that is inflamed (prostatitis) or enlarged (BPH) can boost PSA levels, yet further testing may show no evidence of cancer. 3  Some BPH drugs can lower PSA levels, despite the presence of prostate cancer, called a false negative.

10 ways to lower your PSA levels An elevated PSA can be an early indication that something is not quite right with the prostate, such as the possibility of prostatitis, an enlarged prostate, or prostate cancer, while a lower PSA is a strong indication of good prostate health.

Does A High PSA Level Mean I Have Prostate Cancer? The simple answer to this is no. An elevated PSA number does not always indicate a man has prostate cancer. The PSA test is a blood test used to measure a substance in the blood called prostate specific antigen. It is often the first step in screening for prostate cancer along with the second screening test which is a digital rectal exam (DRE).

Raised PSA 1 PSA is not a specific test for prostate cancer. 2  Raised levels may also be caused by inflammation, benign enlargement or previous surgery. 3  With PSA levels between 3 and 10, only 20% of men have prostate cancer on biopsy. 4  Higher levels of PSA make prostate cancer more likely (50% chance with a PSA greater than 10).

Prostate Biopsy Is Not Always Necessary, New Finding Suggests Researchers have discovered that some elevated prostate-specific antigen (PSA) levels in men may be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy.

The Weird Thing That Can Mess with Your Prostate PSAs are proteins formed by cells in the prostate gland. Previously, elevated PSA levels acquired from a simple blood test were believed to be a huge red flag for prostate cancer, says Dr. Kohli. Nowadays, most doctors know that high PSA levels could be false alarms to cancer. The big C isn’t the only thing that can cause these levels to rise—benign conditions like inflammation, infection, or enlargement of the prostate can increase them, too.

What a High PSA Level Means if Itâs Not Prostate Cancer PSA tests measure a protein in your blood called prostate specific antigen, or PSA. Prostate cancer makes PSA levels go higher, but high PSAs aren't always a sign of prostate cancer. Sometimes, readings may be elevated because of something benign, such as ejaculating within 24 hours of the test.

Prostate-Specific Antigen (PSA) Blood Test Just as important as the PSA number is the trend of that number (whether it is going up, how quickly, and over what period of time). It is important to understand that the PSA test is not perfect. Most men with elevated PSA levels have noncancerous prostate enlargement, which is a normal part of aging.Conversely, low levels of PSA in the bloodstream do not rule out the possibility of prostate cancer.

- 1 Men with a PSA level below the age-specific limit of normal can have PCa. 2  Moreover, many men with a PSA level between the age-specific upper limit of normal and 10 ng/mL will not have PCa. 3  This is due to the fact that PSA is not cancer-specific and is produced by both cancerous and non-cancerous prostate cells.

Does a high PSA blood test mean you have prostate cancer? Is there a PSA level at which prostate cancer risk is zero? According to the Cleveland Clinic and other experts, “There is no PSA level below which the risk of cancer is zero.” In the Danish study, for example, the researchers found that for men with a PSA of 1.0 ng/mL or less, there was still a minute risk: 0.6 to 1.5 percent.

High PSA Level? Check it Again For more information on this topic visit: PSA Levels. May 27, 2003 -- The PSA blood test is commonly used to check for signs of prostate cancer or other prostate problems. When a PSA level comes back high, the next step is often a biopsy. But a new study suggests another course of action: Another PSA test done more than a month later. That's because PSA levels can fluctuate up and down -- so a man with a high PSA level may not actually have any prostate problems at all. In fact, after studying nearly 1,000 men, researchers found that about half of those whose PSA levels were initially high had a normal result in a subsequent test.
