'In the United States, the prevalence of smoking among HIV-infected people is substantially higher than in the general population, and most HIV-infected individuals either currently smoke or have previously smoked,' comment the authors. 'Our findings indicated that a substantial fraction of cancer diagnoses among HIV-infected individuals potentially would not have occurred if they had never smoked.'

Smoking may also contribute to the development of other cancers but more research is needed to understand how it might contribute to the development of these cancers. Smoking was estimated to cause 29% of all cancer deaths in 2010 in the United States."
