Brachytherapy for Cancers of the Brain

Brachytherapy involves implanting tiny radioactive seeds near to tumor tissue, resulting in a high dosage to the tumor and minimal damage to healthy surrounding tissues and organs. Regardless of where a tumor originates, treating brain tumors involves surgical removal and then waiting several weeks for patients to heal before beginning external beam radiation. However, even a few weeks delay in treatment can increase the chance of tumor recurrence. By implanting radioactive seeds during the initial surgery, the chance of tumor recurrence can be greatly reduced. I like this approach because it has minimal damage to non-tumor tissue and does not require the high radiation dosages and the many weeks of follow up treatment necessary with external beam radiation.
