America had witnessed the detection of prostate cancer in 200,000 men in the United States last year. A majority of the positive results were because of PSA tests. The diagnosis basically involves around the presence of a protein known as PSA that is produced by the prostate gland of a person.
The presence of cancer is determined by the prevalence of the protein in a person. If the levels of PSA are found to be higher, then a person is more likely to be suffering from prostate cancer. Men with higher levels of PSA are always advised to undergo a biopsy to check if they are suffering from the condition.
Though, PSA tests have always been recommended by scientists but a recently published report in the Journal of the National Cancer Institute has stated that the tests is not always the best measure of diagnosing someone with prostate cancer. It has further gone ahead and said that PSA tests also lead to people undergoing unnecessary biopsies.
Talking about PSA levels, a Biostatistician at the Memorial Sloan-Kettering Cancer Care Centre in New York, Andrew Vickers, informed that men should not be worried about tests that show they happen to have high levels of PSA especially if the overall levels of PSA are low.
