Ovarian tumors in children are most common during adolescence. Symptoms can include nausea, vomiting, pain, constipation or problems with urination. Testicular tumors are most commonly found in male children during infancy or after puberty. Tumors are normally discovered during a testicular examination. The tumors are painless and usually feel like a small hard mass in the testis.
Germ cells develop while the child is still in the womb.
The germ cells move through the developing child to the area where the sex organs will grow. It is in the path of the germ cell where a germ cell tumor can develop. Even though this tumor develops when the child is in the womb, there is nothing that the pregnant mother can do to prevent the tumor from developing. The mother or father is in no way responsible for the child developing a cancerous or noncancerous tumor. Sacrococcygeal teratomas occur mostly in infancy and 70 percent of them in females.
