What is the primary risk factor for developing oral cancer?

Tobacco use is recognized as the primary risk factor for developing oral cancer due to the direct carcinogenic effects of the substances present in tobacco products. The chemicals in tobacco are known to cause mutations in DNA, affecting the cells in the oral cavity and leading to the development of cancer. The risk is significantly higher for individuals who both smoke and consume alcohol, as these two factors can have a synergistic effect, increasing the likelihood of cancer even further.

Moreover, tobacco use includes a variety of products such as cigarettes, cigars, pipes, and smokeless tobacco, each contributing to the risk of oral and other types of cancers. The association between tobacco and oral cancer is well-established, with numerous studies supporting these findings. Public health initiatives focus heavily on reducing tobacco use to lower the incidence of oral cancer, highlighting its critical role as the top risk factor in this context.
