Treatment for embryonal tumors usually involves surgery. Other treatments might be used after surgery to reduce the risk that the tumor may come back. Which treatments are best for your child depends on your child's age. Your child's healthcare team also considers the type of embryonal tumor and its location.

Embryonal tumor treatment options may include:

• Surgery to relieve fluid buildup in the brain. Some embryonal tumors may block the flow of fluid in the brain. This can cause a buildup of fluid that puts pressure on the brain, called hydrocephalus. To reduce the pressure, a brain surgeon, also called a neurosurgeon, can create a pathway for the fluid to flow out of the brain. Sometimes this procedure can be combined with surgery to remove the tumor.
• Surgery to remove the tumor. A brain surgeon removes as much of the tumor as possible. The surgeon takes care not to harm nearby tissue. Typically, children with embryonal tumors receive additional treatments after surgery to target any remaining cancer cells.
• Radiation therapy. Radiation therapy uses powerful energy beams to kill tumor cells. The energy can come from X-rays, protons and other sources. During radiation therapy, a machine directs beams of energy to specific points on the body. Standard radiation uses X-rays. A newer form of radiation uses proton beams. Proton beam radiation can be carefully targeted to deliver the radiation to the area of the tumor or other areas at risk. This lowers the risk of hurting nearby healthy tissue. Proton beam therapy is available at a limited number of healthcare centers in the United States.
• Chemotherapy. Chemotherapy uses strong medicines to kill tumor cells. Many chemotherapy medicines are given through a vein, but some are taken in pill form. Chemotherapy may be recommended after surgery or radiation therapy. Sometimes it's done at the same time as radiation therapy.
• Clinical trials. Clinical trials are studies of new treatments. These studies give your child a chance to try the latest treatment options. The risk of side effects for these treatments may not be known. Ask a member of the healthcare team whether your child can participate in a clinical trial.
