Prostate-Specific Antigen (PSA) Test - NCI - National Cancer Institute Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland Both prostate cancer and several benign conditions (particularly benign prostatic hyperplasia, or BPH, and prostatitis) can cause PSA levels in the blood to rise The PSA test measures the level of PSA in the blood
Understanding Prostate Changes and Conditions - National Cancer Institute When men are in their 20s, the normal prostate is about the size of a walnut By the time a man is 40 the prostate may have grown slightly larger, and by age 60, the prostate is often the size of a lemon Prostatitis can raise a man’s PSA level Signs and symptoms of types of prostatitis There are four major types of prostatitis Each
PSA Velocity Does Not Improve Prostate Cancer Detection In that clinical trial, men ages 55 or older with a PSA level below 3 0 ng ml and a normal DRE result at study entry were randomly assigned to receive either the drug finasteride or a placebo In addition to receiving regular PSA tests and a prostate biopsy recommendation for PSA levels of 4 0 ng ml or higher, the majority of these men also
Prostate Cancer Screening Results from PLCO - NCI When age-adjusted PSA levels are used, a different PSA level is defined as normal for each 10-year age group Doctors who use this method generally suggest that men younger than age 50 should have a PSA level below 2 4 ng mL, while a PSA level up to 6 5 ng mL would be considered normal for men in their seventies
Prostate Cancer Treatment - NCI - National Cancer Institute A normal prostate does not block the flow of urine from the bladder An enlarged prostate presses on the bladder and urethra and blocks the flow of urine PSA levels may also be high in men who have an infection or inflammation of the prostate or BPH (an enlarged, but noncancerous, prostate)
Prostate Cancer Screening (PDQ®) - NCI - National Cancer Institute Alteration of PSA Cutoff Level Several authors have explored the possibility of using PSA levels lower than 4 0 ng mL as the upper limit of normal for screening examinations One study screened 14,209 White men and 1,004 Black men for prostate cancer using an upper limit of normal of 2 5 ng mL for PSA
Prostate Cancer Screening | Cancer Trends Progress Report Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland The PSA test measures the level of PSA in a man’s blood For this test, a blood sample is sent to a laboratory for analysis In 2012 the U S Preventive Services Task Force (USPSTF) recommended against prostate cancer screening
PSMA PET-CT Accurately Detects Prostate Cancer Spread Under the approval, the tracer can be used in PET imaging for prostate cancer that is suspected of having spread to other parts of the body Ga 68 PSMA-11 can also be used in men who have been treated successfully for prostate cancer but, because of elevated PSA levels, their disease is suspected of having returned
Conversation on Prostate Cancer Prevention and Finasteride Interestingly, men born with a deficiency of 5-alpha reductase, a rare genetic condition, have undetectable levels of PSA and do not get prostate cancer So, it made sense that finasteride, already approved for the treatment of male pattern baldness and benign prostatic hyperplasia (BPH), might also reduce the risk of developing prostate cancer
Tumor Markers - SEER Training After radical prostatectomy or radiation therapy, rising levels of PSA indicate residual disease or recurrence Note: test results may be affected by recent prostatic massage or palpation; PSA level should be assayed before digital rectal examination Normal range: 0 - 4 0 ng ml Normal range also varies depending on the patient's age
