Could a natural compound in apples prevent cancer in rare disease patients?

This study tested whether quercetin, a natural compound found in fruits and vegetables, can prevent or delay squamous cell carcinoma (a type of mouth cancer) in people with Fanconi anemia, a rare genetic disorder that raises cancer risk. 48 participants took quercetin pills, and researchers measured changes in cheek cells to see if cancer-related damage was reduced. The goal was to find a safer way to lower cancer risk without harsh treatments like chemotherapy or radiation.
