Early detection of prostate cancer by a DNA test

Every year, all over the world, thousands of men are diagnosed with prostate cancer. Sadly, many of them succumb to it as well. Prostate cancer is the cancer of the prostate gland which is present in the pelvis of men. Sometimes, the symptoms of prostate cancer can be confusing because not only cancer but any other condition which affects the prostate gland can cause similar symptoms. Most commonly, the prostate gland becomes larger in size, and this causes an increase in pressure in the other organs which are present in the male reproductive system.

However, fortunately, prostate gland cancer takes a fairly long time (more than a decade) before it becomes terminal or incurable. However, just like with most other forms of cancer, the earlier it is detected, the better are the chances of survival of the patient. Many patients with prostate cancer have a genetic predisposition for the diseases which can be found out by prostate cancer gene testing. Genetic alterations are responsible for genetic predisposition of many patients for prostate cancer. 15 out of every 100 patients are genetically predisposed to this alteration which means this mutation runs in their family. If a member of the family suffers from prostate cancer, the chances of yet another family member acquiring the disease almost get doubled. A DNA test will also help in diagnosing whether the family member is suffering from prostate cancer. In addition, to family history, there are various other factors which increase the risk of prostate cancer in males. A diet, rich in fats has been linked to prostate cancer.

By performing DNA testing, the cells that cause the prostate cancer can be easily detected. If the DNA testing for prostate cancer confirms a genetic alteration, then the patient can be presented with several different options for treatment of prostate cancer which may include surgery, hormone therapy, and chemotherapy.

The diagnosis of the prostate cancer is done by performing a rectal exam on the patient. Blood work is also run on the patient to test for the increase in the levels of PSA which is Prostate Specific Antigen. The levels of this antigen are found to be high in the blood in cases of prostate cancer.
