Interesting discovery: A dye will help neurosurgeons to get complete resection surgeries for brain tumors.

A new study in 99 patients with suspected high-grade (fast-growing) gliomas were colored after given a drink containing 5-ALA before surgery. "The beauty of 5-ALA is that neuro-surgeons can see where high-grade glioma is, while they're operating.". The use of 5-ALA  will help to get complete resection of the brain tumors and increase the chance of cur in these patients.
