Is Germinoma cancerous?
Germinomas are usually malignant (cancer) but tend to grow and spread slowly and can usually be cured. They are the most common type of central nervous system germ cell tumor. They usually occur in teenagers and young adults.
Is Germinoma benign or malignant?

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.
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 Pineocytoma?
A pineocytoma is a tumor of the pineal gland, a small organ in the brain that makes melatonin (a sleep-regulating hormone). Pineocytomas most often occur in adults as a solid mass, although they may appear to have fluid-filled (cystic) spaces on images of the brain.
Do germ cell tumors come back?
How do providers treat benign (noncancerous) ovarian germ cell tumors? Healthcare providers remove benign tumors surgically. Sometimes, they need to remove the ovary (or part of the ovary) when removing the tumor. Benign tumors rarely grow back after providers remove them.
Can germ cell tumors spread?
Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes, and central nervous system. Rarely, germ cell tumors can spread to the bone, bone marrow, and other organs.
How common is Germinoma?
How common is germinoma? Altogether, germ cell tumors account for 3.8% of primary brain tumors in children and adolescents. In 2019, an estimated 340 new germ cell tumor cases were diagnosed in the United States. Germinomas are thought to account for at least a third of those cases.
What is metastatic 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.
