Extracranial germ cell tumor
Extracranial Germ Cell Tumor
Extracranial Germ Cell Tumor (pronunciation: ex-tra-kra-nee-al germ cell too-mor) is a type of cancer that originates from germ cells. Germ cells are the cells that develop into sperm and eggs.
Etymology
The term "extracranial" is derived from the Latin words "extra" meaning outside and "cranium" meaning skull. "Germ cell" is derived from the German word "Keimzelle" which means seed cell or germ cell. "Tumor" is derived from the Latin word "tumere" which means to swell, referring to the abnormal growth.
Definition
Extracranial Germ Cell Tumors are tumors that occur outside the brain, in the germ cells. These tumors are most commonly found in the ovaries in women and the testes in men, but can also occur in other parts of the body. They are most common in adolescents and young adults.
Types
There are two main types of Extracranial Germ Cell Tumors: seminomas and non-seminomas. Seminomas are slow-growing and respond well to treatment, while non-seminomas are more aggressive and may require more intensive treatment.
Symptoms
Symptoms of Extracranial Germ Cell Tumors depend on the location of the tumor. Common symptoms include lumps in the testes or ovaries, abdominal pain, and lower back pain.
Diagnosis
Diagnosis of Extracranial Germ Cell Tumors typically involves a physical examination, blood tests to check for tumor markers, and imaging tests such as ultrasound, CT scan, or MRI.
Treatment
Treatment for Extracranial Germ Cell Tumors depends on the type and stage of the tumor, and may include surgery, chemotherapy, and radiation therapy.
Prognosis
The prognosis for Extracranial Germ Cell Tumors varies depending on the type and stage of the tumor, but overall survival rates are high, particularly for seminomas.
