Risk factors

Tobacco use, particularly smokeless tobacco, puts you at high risk of leukoplakia and oral cancer. Long-term alcohol use increases your risk, and drinking alcohol combined with smoking increases your risk even more.

Hairy leukoplakia

People with HIV/AIDS are especially likely to develop hairy leukoplakia. Although the use of antiretroviral drugs has reduced the number of cases, hairy leukoplakia still affects a number of HIV-positive people, and it may be one of the first signs of HIV infection.
