The use of PSA screening, however, can lead to both overdiagnosis and overtreatment. Many prostate cancers are slow-growing and may never result in harm or shorten life.“Using the PSA test to screen men for prostate cancer is controversial because it is not yet known for certain whether this test actually saves lives. Moreover, it is not clear that the benefits of PSA screening outweigh the risks of follow-up diagnostic tests and cancer treatments.There is no specific normal or abnormal level of PSA in the blood. In the past, PSA levels of 4.0 ng/mL and lower were considered normal. However, some individuals with PSA levels below 4.0 ng/mL have prostate cancer and many with higher PSA levels between 4 and 10 ng/mL do not have prostate cancer (1).
Does a PSA of 20 mean cancer : Your doctor will likely investigate anything over 10. Anything greater than 20 starts pointing more toward cancer. Anything above 50 is usually a very strong indicator of prostate cancer. Levels that high are usually not due to an infection or some other thing going on.
Why is PSA no longer recommended
PSA tests aren't foolproof. It's possible for your PSA levels to be elevated when cancer isn't present, and to not be elevated when cancer is present. For some men, knowing is better than not knowing.
Is PSA test still recommended : The U.S. Preventive Services Task Force (USPSTF) recommends that men ages 55 to 69 years discuss the possible benefits and harms of prostate-specific antigen (PSA) screening with their health care provider and make an individualized decision about whether to get screened.
The false-positive PSA rate was 46.8% (95% CI 44.2–49.2%), and the false-negative PSA rate was 2.8% (95% CI 2–3.5%). Median follow-up was 19.51 months (IQR 14.39–22.24), and median follow-up until the patient was diagnosed with PCa was 5 months (IQR 11–16). Misleading results.
The test doesn't always provide an accurate result. An elevated PSA level doesn't necessarily mean you have cancer. And it's possible to have prostate cancer and also have a normal PSA level.
Can you have a PSA of 20 and not have prostate cancer
Elevated PSA levels can indicate the presence of cancer, but high PSA levels can also be a result of non-cancerous conditions like benign prostatic hyperplasia (BPH), or an infection. PSA levels also rise naturally as you age. Elevated PSA levels do not necessarily mean that you have prostate cancer.What is an alarming PSA level A PSA level of 10 ng/ml or higher means you have a greater risk of prostate cancer.“However, this research highlights that a PSA test for early detection can do more harm than good – it's simply not accurate enough and can lead to some men having tests and treatment that they don't need. Screening finds prostate cancer in some men who would never have had symptoms from their cancer in their lifetime. Treatment of men who would not have had symptoms or died from prostate cancer can cause them to have complications from treatment, but not benefit from treatment. This is called overdiagnosis.
Is a PSA test meaningless : Prostate-specific antigen (PSA) screening is not the panacea that enthusiasts hoped for, but it is not worthless. Men who have elevated PSA need to be aware that a prostate biopsy can identify both clinically significant and insignificant cancers and that intervention can affect quality of life.
Does ejaculating lower your PSA : Absolute and relative change in serum PSA concentration, as well as the time to return to baseline PSA concentration following ejaculation, were assessed. Results: The serum PSA concentration increased following ejaculation in 87% of the subjects.
How bad is a PSA of 25
A percent-free PSA above 25% is considered normal. Some doctors recommend that if you have a percent-free PSA of 18% or less you should have a prostate biopsy. Other doctors recommend having a biopsy if the percent-free PSA is around 12% or less. Methods: Patients were divided into groups according to diagnostic PSA level: <20, 20-≤100, 100-≤200 ng/mL, 200-≤500 ng/mL, and >500 ng/mL. Outcomes measured include overall survival and prostate cancer-specific mortality.In general: For men in their 40s and 50s: A PSA score greater than 2.5 ng/ml is considered abnormal. The median PSA for this age range is 0.6 to 0.7 ng/ml. For men in their 60s: A PSA score greater than 4.0 ng/ml is considered abnormal.
Why is PSA screening no longer recommended in healthy men : Because prostate cancer often grows slowly, men without symptoms of prostate cancer who have less than a 10-year life expectancy should not be offered prostate cancer screening, because they aren't likely to benefit from it. Overall health status, and not age alone, is important when making decisions about screening.
