Forbes: Chemical 'Paint' Helps Surgeons See Cancer's Borders

"Researchers say they've developed a tumor "paint" that illuminates cancerous cells and help surgeons spot the borders of tumors.
A team at Seattle Children's Hospital Research Institute and the Fred Hutchinson Cancer Research Center found that the paint -- a protein derived from scorpions called chlorotoxin -- helped surgeons distinguish between brain tumor cells and normal brain tissue during surgery.

"My greatest hope is that tumor paint will fundamentally improve cancer therapy. By allowing surgeons to see cancer that would be undetectable by other means, we can give our patients better outcomes," study senior author Dr. James M. Olson said in a prepared statement."
