An in-depth report on the causes, diagnosis, and treatment of brain tumors.
Gliomas; Medulloblastoma
Cell Phones and Brain Tumors
Cell phones and other wireless devices do not cause brain cancer, according to several 2006 studies. The researchers studied how many years people had used mobile phones, and how long they usually talked on the phone, and found no association with gliomas.
Genetic Testing and Treatment
Scientists continue to investigate how genetic testing of tumors can help predict survival and determine treatments.
Radiotherapy for Low-Grade Glioma
A “wait and see” approach to radiation therapy is appropriate for patients with low-grade gliomas, indicates a 2005 Lancet study. Researchers found that radiotherapy immediately after surgery extended the time it took for cancer to progress, but did not affect overall survival. The researchers suggest that patients with low-grade gliomas who are in good condition can delay radiation therapy as long as they are carefully monitored.
Medulloblastoma Treatment
A new approach to radiotherapy and chemotherapy may help double the chances for 5-year survival in children with high-risk medulloblastoma, suggests research in Lancet Oncology . In the study, children with high-risk brain tumors received a higher dose of radiotherapy to the neck and spine than children with standard-risk cancer, and a shortened course of chemotherapy.
Brain Tumors in Children
According to a 2006 study, children with brain tumors exhibit the following symptoms:
