Human cells grow all the time. This is a specific way the body replaces useless cells with new ones. The new cells remain on the same tissue of organ, assuming the same function as the old ones. This is a controlled growing targeting the body development process.

Sometime the cells begin to grow out of control and form a mass called tumor. Tumors are cancerous only if they are malignant. This means due of uncontrolled growth they leave the 'parental' place and invade nearby tissues or spread throughout the body.

Prostate cancer happens when cells in prostate begin to multiply out of control and leave the prostate gland.

Treatment for prostate cancer may vary according to the stage of the cancer. Regular screening for prostate cancer can help in early diagnoses and in treatment effectiveness.

The most usual screening is done by routine yearly digital rectal examinations (DRE) beginning at age 40. The procedure involves a gloved finger in the rectum for a measurement of the size of the gland and feel for possible prostate tumor (nodule) cancer.

In addition, beginni

ng at age 50, an annual PSA test is necessary because it is substantially more sensitive for men health than DRE when it comes to detecting early, tiny, or even microscopic cancers that are confined to the prostate gland.

But in many cases PSA testing is irrelevant as many men with normal test results are prostate cancer sufferers. Recent studies have found that a simple urine test may improve the diagnosis and treatment of this male disease. Urine screening can reveal the presence of thymosin ß15, a protein that sustain malignum tumor development by stimulating cell migration. This protein is produced almost exclusively by cancerous cells and it is detectable in urine.
