Abstract PIP: An investigation of the incidence of carcinoma of the palate, its relation to reverse smoking, and the age and sex prevalence of these patients (with carcinoma of the hard palate in particular) as compared to patients with other oral carcinomas was undertaken from September 1970 to October 1973. Records of 600 consecutive patients with cancer of the oral cavity and oropharynx at the King George Hospital in Visakhaptnam were compared with controls matched in age, sex, economic status, education, occupation, religion, and origin. The incidence of cancer of the hard palate was 54.8\% overall and 73.8\% among females (soft-palate carcinomas were rare with only 8 in males and 4 in females). The mean age of males with hard palate carcinoma 50.4 + or - 11.23) was significantly different from that of females (45.4 + or - 10.37). Reverse smoking predominated in cancer patients, but other habits were prevalent in controls. The risk of developing hard palate carcinoma increased for females 132 times with reverse smoking of chuttas. Reverse smoking allows particulate material (including carcinogens) from the smoke to enter glad openings of the hard palate which do not empty as effectively as do those of the soft palate.
