Some studies in Australia, Brazil and Germany pointed to alcohol-containing beverages as being potential causes of oral cancer.

Heavy chronic consumption of alcohol, particularly alcoholic spirits, is also a significant risk factor of laryngeal cancer.  A 2008 study suggests that acetaldehyde (a breakdown product of alcohol) is implicated in oral cancer, but this study specifically focused on abusers of high ABV alcohol.

Whitnessed a person frequenting the same drinking places that I do from 2015 - 2018. He got a 2nd degree laryngeal cancer, later metastasized into his mouth and then going gingival. Oncologist and surgeons tried to save as much as they could. He later wasn't able to speak, his neck was swollen like a frog. When he tried to drink, he barely couldn't hold the liquid in his mouth and it always must have been room-temperatured, because the cold and cooled beverages caused massive pain in his palatopharyngeal area.
I remember he was salivating all the time. After he left the place, you could tell he was there because he left his drooled hankies all over the place which was disgusting, because somebody had to remove them.
He died after his 3rd operation. Barely able to breath, nor his life was fullfilling anymore. Shit into a bag, tube-fed, being grumpy all the tiime.

Since he was in love with drinking Jack Wieber Whisky World's "Classic of Islay" - I do refer to that spirit as "Classic of Cancer". High proof Islay Single Malt Scotch Whisky. Peated to a wonderful, cancerous 40 ppm.

But this might be just an isolated case. Who knows...
