THE PSA IS a good initial “check engine light” for the prostate, says Garrett Pohlman, M.D., a urologist and host of The Prostate Health Podcast. But it can just tell you that PSA levels are ...
A subsequent increase in PSA levels by 2.0 ng/mL [disputed – discuss] above the nadir is the currently accepted definition of prostate cancer recurrence after radiation therapy. [citation needed] Recurrent prostate cancer detected by a rise in PSA levels after curative treatment is referred to as a "biochemical recurrence". The likelihood of ...
PSA levels between 4 and 10 suggest you could have about a 25 percent chance of prostate cancer, and levels over 10 signal that your chance of having the cancer is more than 50 percent.
Men with high PSA levels are often recommended to repeat the blood test four to six weeks later, as PSA levels can fluctuate unrelated to prostate cancer. [17] Benign prostatic hyperplasia, prostate infection, recent ejaculation, and some urological procedures can increase PSA levels; taking 5α-reductase inhibitors can decrease PSA levels. [15]
After surgery or radiation therapy, PSA may start to rise again, which is called biochemical recurrence if a certain threshold is met in PSA levels (typically 0.1 or 0.2 ng/ml for surgery). At 10 years of follow-up after surgery, there is an overall risk of biochemical recurrence of 30–50%, depending on the initial risk state, and salvage ...
If PSA levels are checked and are high, then further investigation is warranted. Measures including PSA density, free PSA, rectal examination, and transrectal ultrasonography may be helpful in determining whether a PSA increase is due to BPH or prostate cancer.
