Early Detection of Prostate Cancer

Traditionally, the technique for early detection of this cancer was the digital rectal examination, in which the doctor introduced a finger into the rectum and can feel the prostate gland to observe if there were suspicious nodules. In latest years, it could be a laboratory test: the detection of prostate specific antigen, called PSA. This test was originally introduced as a laboratory test for diagnosing and monitoring prostate problems and then was proposed as early diagnostic test.

The PSA is a protein created by cells of the prostate gland. Analysis of PSA assesses the concentration in the blood. A sample of blood and is measured in the laboratory the amount of PSA that includes the sample. However, it is normal for men to have low levels of PSA in their blood, benign (not cancerous) possibly will add to the concentration of PSA.

The PSA level alone does not give enough information in order that physicians can differentiate between benign prostate conditions and cancer. However, the doctor will take into consideration the result of this analysis to make a decision whether to investigate further for signs of prostate cancer.



The elevated PSA might indicate a prostate cancer but might also indicate other conditions like benign prostatic hyperplasia, or infection. For that reason, PSA can be deemed a unique indicator of prostate cancer, but it is high, begin a diagnostic process.

The suggestions of physicians concerning the screening vary. A number of recommend annual screening tests for men over 50 years of age and a number of advise men who have a higher risk of prostate cancer to start screening at 40 or 45 years old.

Some risk factors add to the possibilities that a man is suffering from prostate cancer. These factors might be considered when a doctor suggests screening. Age is the most general risk factor, because nearly 65 percent of prostate cancer cases happen in men 65 years of age or older. Other risk factors for prostate problems consist of race, family history and possibly diet.
