These tumours develop from germ cells. In the developing embryo germ cells migrate to the ovaries or testicles and form the ova (egg cells) or sperm cells. Germ cell tumours occur where these cells become cancerous. These tumours typically express high
levels of alphafetoprotein (AFP). Germ cell tumours are most common in children and young adults, there are different sub-types including endodermal tumours (mostly found in children), dysgerminoma, teratoma, and seminoma (young men).
The most common location of these tumours are the ovaries (in females) or testicles (in males). However, they can also develop in other parts of the body such as the sacrococcygeal region, brain, abdomen and other sites - this may occur when some of the
germ cells in the embryo did not migrate properly. For information on germ cell tumours of the brain see the section on brain tumours.
Note: germ cell tumours in children tend to be quite different to those in adults.
