The increase in number of men affected by prostate cancer has made it a matter of concern, as it comes out to be the second leading cause of deaths among the American men. There are various levels of PSA in the blood, which act as indicators and put forth the probability of a man to develop this type of cancer.
This hysterical growth of abnormal cells sometimes is said to involve the entire gland and develop into a serious cancer. It is said to make an easy way towards the lymph nodes and the bones, and hence have a direct impact on them.
Also, there is one particular type of molecule, namely the prostate specific antigen (PSA) which is released by the prostate gland into the body. Testing the blood for this particular molecule helps in early detection of the disease.
For all men whose PSA level varies from 0 to 4 nanograms per milliliter (ng/ml) of blood are on the safer side and the ones with PSA between 2.5 to 4 ng/ml, are said to have developed prostate cancer.
For men who have had a history of the disease must get their PSA level checked and also see to it if their prostate feels abnormal, as it is not just about the level of PSA, but also about any kind of abnormality.
