Impact of smoked and smokeless tobacco on oral epithelium: A comparative study in Jazan region.
Researchers examined mouth cell damage in tobacco users versus non-users in Saudi Arabia's Jazan region. Both smokers and smokeless tobacco users showed signs of cellular injury and genetic damage, with smokers showing more severe changes. The damage increased with longer tobacco use, suggesting regular screening could help catch early warning signs of oral cancer.
Relevance to India: India has high rates of both smoked and smokeless tobacco use (including chewing and snuff), making findings on oral epithelial damage from these forms directly applicable to Indian populations at risk for oral cancer.
