Healthbeat Segment: Shaking Up Cancer

Abstract:
Scientists have discovered a new approach to fighting cancers that cannot be destroyed by radiation or chemotherapy.

It's a new twist on what's known as nanomedicine. It's an experimental therapy that does not involve drugs or heat. Instead, the cancer is outsmarted by simply being pushed around.

"It is a very devastating disease for which there is absolutely no cure," said Dr. Maciej Lesniak, neurosurgeon, University of Chicago Medical Center.

Malignant gliomas are cancerous brain tumors that kill thousands of Americans each year.

"No matter what we do these tumors tend to come back and grow," said Dr. Lesniak.

Chemotherapy radiation and surgery can buy patients some time but not for long. That's why neurosurgeon Maciej Lesniak and colleagues are so excited about some ultra tiny discs and an unlikely microscopic approach to killing off these stubborn cells.

"The approach, for lack of a better word, is very cool because we are trying to destroy these cancer cells through a mechanical process," said Dr. Lesniak.

During the process, the cancer cells are literally shaken by ultra tiny magnetic microdiscs which are clinging to the surface of the cancer.
