Testicular cancer starts in the cells of a testicle they are part of a man’s reproductive system. Two egg-shaped organs found in the sac of loose skin (scrotum) at the base of the penis.
The testicles are held in the scrotum by the spermatic cord. The spermatic cord contains the ductus deferens, some lymph nodes, veins and nerves. Testicles make the male sex hormone testosterone and sperm. The sperm begins to form in “germ” cells inside the testicles.
Most testicular cancers start in the germ cells and are called germ cell tumours. There are two main types of germ cell tumours. — Seminomas and non-seminomas. Each type grows differently and is treated differently. Both types can be treated successfully if detected early.
