Summary

This study tested whether quercetin, a natural substance found in some foods, could help prevent a type of mouth cancer in people with Fanconi anemia, a rare genetic condition that raises cancer risk. 48 participants took quercetin to see if it reduced certain cell changes linked to cancer. The goal was to find a safer way to delay or avoid harsh cancer treatments.
