Prostate specific antigen (PSA) is a substance that’s only produced by the prostate gland. The protein is quite beneficial inside the diagnosis of prostate cancer mainly because it acts as a sign of prostate cancer when it’s elevated in a blood sample. Under normal conditions, PSA levels in a majority of males are identified to be below 4ng/ml which is employed as a reference value when diagnosing the condition. In men suffering from prostate cancer, PSA levels are usually above the reference value though there could be other underlying aspects causing the elevated level. Studies have shown that, males with a PSA degree of in between four and 10 have a 25% opportunity of suffering from prostate cancer while those with levels above 10 have a 67% risk of suffering from the condition.
The levels of PSA in males are influenced by age, and they tend to be lower in younger men and greater in older men. This consequently indicates that, the reference value varies inside the two age groups where by a value of 2.5 ng/ml is used as the reference value in younger males whilst 4ng/ml is used in older males. PSA test need to not be taken as probably the most appropriate test for ruling the presence or absence of prostate cancer but further tests ought to be carried out to create a definitive diagnosis.
The test is meant for several categories of men but usually, the test is open for every man over the age of 40 with or with out symptoms of prostate cancer. Several of the factors that would make a man to go for a PSA test are the presence of symptoms that are associated with the condition, have been exposed towards the risk elements which are most likely to cause prostate cancer or comes from a loved ones that has a history of prostate cancer, and is being treated for prostate cancer which makes the test an critical follow-up test.
PSA test is carried out by drawing blood from the arm following which the blood sample is taken towards the laboratory for PSA screening. Outcomes don’t take long to acquire and they are reported in nanograms of PSA per milliliter of blood.
PSA test is limited by some elements which make the test to give false-negative or positive results. Elevated levels of PSA may happen because of other conditions and this might be taken to be a sign of prostate cancer if further tests are not carried out. Unnecessary remedy may possibly commence to be given towards the patient adding additional trouble towards the individual getting treated for the wrong illness. Negative outcomes may well also turn out to be misleading making the patient to be treated for one more illness instead of prostate cancer which may well also have adverse effects on the patient within the long run. It can be consequently critical for physicians to come up with a definitive diagnosis in order to provide essentially the most proper therapy towards the patient.
PSA test for prostate cancer is very helpful within the diagnosis and therapy of prostate cancer and it cannot be undermined in fighting prostate cancer.
