New study aims to spot mouth cancer sooner in smokers and drinkers

This study looked at whether training health workers and actively reaching out to smokers and heavy drinkers aged 35+ can get more of them to have a simple mouth exam for early oral cancer detection. Over 1,100 people from Rio de Janeiro's primary care clinics took part. The goal was to see which strategy—standard care, phone reminders, or a public campaign—works best to catch the disease early.
