Living with Nongerminomatous germ cell tumor

A cancerous tumor, found in the brain, chest, or abdomen, that starts from cells meant to form sperm or eggs.

Understanding Nongerminomatous germ cell tumor

Nongerminomatous germ cell tumors are cancerous tumors that start from cells that were meant to form sperm or eggs.

They are commonly found in the pineal gland in the brain, in the mediastinum (the middle of the chest), or in the abdomen. They are often large and tend to spread faster than the other type of germ cell tumor, called seminoma. Possible early signs include chest pain and breathing problems.
