Embryonal tumor
Embryonal Tumor
Embryonal tumor (pronunciation: em-bree-o-nal too-mor) is a type of neoplasm that originates from embryonic tissue. The term is derived from the Greek words 'embryon' meaning 'unborn' and 'oma' meaning 'tumor'.
Definition
An embryonal tumor is a cancer that arises from cells that remain from the very early stages of a person's development in the womb. These tumors are most commonly found in children, although they can occur at any age.
Types
There are several types of embryonal tumors, including:
- Neuroblastoma: This is the most common type of embryonal tumor. It usually starts in the adrenal glands, which are on top of the kidneys, but can also develop in nerve tissue along the spine, chest, abdomen, or pelvis.
- Wilms' tumor: This is a kidney cancer that is most common in children. It is also known as nephroblastoma.
- Hepatoblastoma: This is a very rare cancer that starts in the liver. It is most common in children under the age of 3.
- Retinoblastoma: This is a rare cancer that starts in the retina, the back part of the eye.
- Medulloblastoma: This is a cancer that starts in the cerebellum, the part of the brain at the back of the skull.
Symptoms
The symptoms of an embryonal tumor depend on where in the body the tumor is located. However, common symptoms can include:
- A lump or swelling in the body
- Pain
- Fatigue
- Weight loss
- Changes in vision or hearing
Treatment
Treatment for embryonal tumors typically involves a combination of surgery, chemotherapy, and radiation therapy. The exact treatment plan will depend on the type of tumor, its location, and the patient's overall health.
Prognosis
The prognosis for an embryonal tumor varies widely depending on the type of tumor, its location, and the stage at which it is diagnosed. However, with early detection and treatment, many people with these types of tumors can have a good prognosis.
