Interventions
Participants were invited for 3 rounds of oral cavity cancer screening, conducted 3-years apart. Screening was conducted by health workers trained to perform visual inspection of the oral mucosa and identify potential precancerous lesions or oral cancer. Lesions found were referred to a weekly clinic for further evaluation by dentists and oncologists with experience in the diagnosis of oral lesions. Oral precancerous lesions were surgically excised whenever possible and those with confirmed oral cancer were referred for appropriate treatment with surgery, radiotherapy, and/or chemotherapy.
