A specially engineered chewing gum could offer an unexpected new weapon against viruses and bacteria linked to head and neck cancer. In laboratory tests using samples from cancer patients, researchers found that extracts from the gum reduced levels of human papillomavirus, or HPV, by as much as 93%. An enhanced version also nearly eliminated two harmful bacterial species while leaving beneficial bacteria unharmed.

The findings, reported in Scientific Reports , suggest that this experimental approach could eventually help prevent certain infections and support existing cancer treatments. Researchers believe the plant-based technology could also provide a more affordable option for patients.

The research was led by Henry Daniell of the University of Pennsylvania's School of Dental Medicine.…
