Enlarged prostate in men has become a major health problem, globally, during the last few decades. If untreated, this problem can turn into cancer and even cause death. Studies have shown that prostate cancer is the second most frequently diagnosed cancer in men, worldwide and the fifth most common cancer overall.
The prostate specific antigen test is a widely accepted serum marker used for detecting prostate cancer and monitoring its progression in patients.
If a man has a PSA level above 4.0 ng/ml, doctors often recommend a prostate biopsy to determine whether prostate cancer is present. The higher a man’s PSA level, the more likely it is that he has prostate cancer. Moreover, a continuous rise in a man’s PSA level over time may also be a sign of prostate cancer.
