Dear Smita,
The ideal screening method for oral cancer in low resource countries is Visual Inspection. Pre-cancerous lesions like leukoplakia, melanoplakia, erythroplakia,oral submucous fibrosis and indolent ulcers can be easily detected by periodic examination of the oral cavity of the at-risk populations.It will be cost effective as well as feasible.
I concur that visual inspection is the most feasible in resource-crunched regions. However, it is effective to target the high-risk population especially males - tobacco chewers, alcohol drinkers, etc.
I totally agree with the previous opinions. Oral examination is the best choice for the oral cancer detection in such conditions. The challenge is to know where are the high risk individuals and offer them a periodic oral examination. In my district we are mapping these individuals in the areas attended by Family Health Program, with the help of health agent workers.
