Instead, there is a different low PSA level for each patient, called a nadir. The most widely accepted definition is a PSA that has risen from nadir by 2 ng/mL or more." Of course, it means that the monitoring of PSA levels will continue to be a source of anxiety. I wonder how long it will take for PSA to reach its new "normal" level. Thanks again.
Variations in PSA like yours aren’t particularly remarkable. In fact, fluctuations in PSA of up to 36% from one day to the next may have nothing to do with cancer. Prostate infections and inflammation may account for some of the variation, as can an enlarged prostate and advancing age. Treatment of chronic prostatitis with elevated PSA by antibiotics and anti-inflammatory agents can decrease the elevated PSA to the normal levels. Nevertheless, the opportunity of clinically potential prostate cancer remains in patients with a decreased PSA level of less than 4 ng/mL, even also if PSA decreases to less than 2.5 ng/mL.The levels of PSA in men immediately following treatement should be undetectable, Pantuck said. If PSA can be detected, it's an indication of an aggressive cancer that is likely to progress. The men in Pantuck's study all had detectable PSA following treatment. Of the 50 men enrolled, more than 80 percent experienced improvement in doubling times.
Our scientists pursue every aspect of cancer research—from exploring the biology of genes and cells, to developing immune-based treatments, uncovering the causes of metastasis, and more. Researchers at Memorial Sloan Kettering Cancer Center have found that change in PSA levels over time - known as PSA velocity - is a poor predictor of
I have been on AS for more than 6 years with regular PSA tests. During this time my PSA has varied between 3.3 and 8.2, recently quite stable around 5.0 - 5.5. ( all values in my profile ). My urologist is not concerned and told me that some patients have varying PSA. Alan
This is because males with elevated PSA levels may not have prostate cancer. It is best to discuss the risks and benefits of prostate cancer screening and the various testing options with a doctor.Learn about the prostate gland, its changes as you age, and the PSA test that can help diagnose prostate cancer.
