Answer 1

Photodynamic therapy (PDT) is a cancer treatment that uses drugs activated by light to kill cancer cells.

Step-by-step explanation:

Photodynamic therapy (PDT) is a cancer treatment that uses drugs activated by light to kill cancer cells. It involves the administration of a photosensitizing drug that is selectively taken up by cancer cells. When the drug is exposed to light of a specific wavelength, it produces a form of oxygen that kills the cancer cells.
