Prostate cancer is the leading malignancy in men over the age of 50. It is due to the abnormal proliferation of prostatic tissue cells. It is often a slow-growing cancer and remains localized at first. Later, it may extend as it spreads to nearby tissues and organs and then metastasizes to other more distant organs (lymph nodes, bones, lungs, etc.) via the bloodstream and the lymphatic system. Preventing such a development by early screening is a major public health issue, all the more so because as life expectancy increases, so does the frequency of this cancer.
