Learn English: Cancer-Hunting Dye Lights Up Bad Cells (normal)

Doctors have developed a dye that can stick to cancer cells and make them glow.

This glowing dye acts like a flashlight, showing surgeons exactly where the cancer is hidden.

By using this dye, surgeons can remove all the cancer cells without damaging the healthy tissue around them.

This could lead to new treatments for many different types of cancer.
