flag A new light-activated treatment killed up to 92% of skin cancer cells in lab tests, sparing healthy tissue.

flag Researchers at the University of Texas at Austin and the University of Porto have developed a new cancer treatment using near-infrared LED light and tin oxide nanoflakes that killed up to 92% of skin cancer cells and 50% of colorectal cancer cells in lab tests within 30 minutes, sparing healthy cells. flag The method works by generating heat when the nanoflakes absorb light, selectively destroying cancer cells. flag The team is now studying the light-heat process and developing devices for future clinical use. flag The treatment is still in early stages but could offer a non-invasive, targeted therapy for skin and colon cancers, which are among the most common cancers worldwide.
