Surgery is the most common treatment for a child with medulloblastoma. Depending on where the cancer is and the type of cancer, your child's doctor may remove as much of the tumor as possible. If the tumor cannot be totally removed, radiation therapy and chemotherapy may also be given. If the cancer is in a place where it cannot be removed, surgery may be limited to a biopsy of the cancer. Radiation therapy can affect growth and brain development, so clinical trials are testing ways to decrease or delay radiation therapy, especially for younger children.
Chemotherapy uses drugs to kill cancer cells.
Chemotherapy may be taken by pill, or it may be put into the body by a needle in a vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells throughout the body. Chemotherapy is being studied to delay the use of radiation therapy in some patients. Clinical trials are studying different chemotherapy drugs for childhood medulloblastoma. Bone marrow transplantation is a newer type of treatment that is being studied in clinical trials.
