Definition

Stage II is divided into stages IIA and IIB. In stage IIA, cancer has spread (1) to tissue just under the skin of the penis. Cancer has spread to lymph vessels, blood vessels, and/or nerves; or (2) to tissue just under the skin of the penis. Under a microscope, the cancer cells look very abnormal or the cells are sarcomatoid; or (3) into the corpus spongiosum (spongy erectile tissue in the shaft and glans that fills with blood to make an erection). In stage IIB, cancer has spread through the layer of connective tissue that surrounds the corpus cavernosum and into the corpus cavernosum (spongy erectile tissue that runs along the shaft of the penis).
