What type of tumor is a germinoma?
A germinoma is a type of germ cell tumor commonly found in the brain. Germ cells typically migrate to the gonads during fetal development and become an egg in female ovaries or sperm in male testes.
Is teratoma a germ cell tumor?
Teratomas are the most common type of germ cell tumor to develop in extragonadal (not in the ovary or testes) areas. Doctors usually treat teratomas with surgery because chemotherapy doesn’t work in a benign tumor.
What causes a germinoma?
Germinomas are rare tumors that primarily occur in children and adolescents. These tumors arise from germ cells, which normally become eggs or sperm after migrating to the ovaries or testes during fetal development. Germinomas occur when these germ cells fail to migrate to the proper location and continue dividing.
Can a teratoma be alive?
In about 1 in 500,000 people, a very rare type of teratoma can appear, called fetus in fetu (fetus within a fetus). This teratoma can have the appearance of a malformed fetus. It’s made up of living tissue.
Are teratomas usually benign or malignant?
Mature teratomas tend to be benign, or non-cancerous. Mature teratomas can present in different ways. They may be: Solid – made of tissue, but not enclosed.
What is a pineal germinoma?
A type of germ cell tumor that is found in the pineal gland in the brain. Symptoms of pineal germinomas include headaches, changes in vision, nausea, and vomiting.
Can you survive germinoma?
Children treated for germinomas have a 90% survival rate. For other types of germ cell brain tumors, radiation therapy can help to control the disease in 40% to 60% of children. If chemotherapy is added, the 10-year overall survival rate is between 70% and 80%.
What is a chordoma?
Chordoma is a slow growing cancer of tissue found inside the spine. Chordoma can happen anywhere along the spine. It is most often found near the tailbone (called a sacral tumor) or where the spine meets the skull (called a clival tumor).
