Unknown to us all, there is a battle raging constantly in our bodies every minute. Our immune system – consisting of macrophages, neutrophils, dendritic cells, natural-killer cells, neutrophils, mast cells, basophils and B cells in the blood – is a biological machine aimed at protecting us from invaders.
Cancer is not a single disease but a whole range of different diseases, the treatment of which is different, the treatment is different, and the prognosis is different. The process of DNA damage that causes uncontrolled division of the cells can begin for various reasons, not always known and clear.

If human health in biblical times was similar to that today, he probably did, because the main factor behind malignancy of the prostate, is aging. Thus, men who live long lives are unlikely to escape some problem with the prostate, such as benign prostatic hyperplasia (non-cancerous enlargement of the gland that makes urination difficult) if not actual cancer.
