Definition from: Cancer.gov

As prostate cancer progresses from Stage I to Stage IV, the cancer cells grow within the prostate, through the outer layer of the prostate into nearby tissue, and then to lymph nodes or other parts of the body. A medida que el cáncer avanza desde el estadio I al estadio IV, las células cancerosas crecen dentro de la próstata, a través de la capa externa de la próstata hacia el tejido cercano y, luego, hasta los ganglios linfáticos u otras partes del cuerpo.
