The Department of Pathology MLN Medical College in Allahabad recently concluded a study called 'age specific incidence rate and pathological spectrum of oral cancer' and has uncovered some very disturbing figures. The study tracked annual data from the tumor registry between 1990 to 2000.
AdvertisementOut of a total of 40,559 biopsies monitored by the department, 759 biopsies were of the oral cavity. Factors like age, sex, risk factors, site and histology were also taken into consideration during the analysis. It was found that grade 1 squammous cell carcinoma (the most malignant and dangerous oral cancer) was prevalent to a high degree in the age group of 50-59 years. 303 malignant cases were uncovered in the 759 biopsies. Again the oral cancer showed a predilection for males with 76.57 percent incidence, while women has a rate of 23.43 percent. Thus the male: female ratio is 3.27:1. The tongue was the most frequently involved site in this cancer. Dr Ravi Mehrotra, who was instrumental in conducting the study, said that the analysis had uncovered statistically significant numbers. "The data reflects our specific patient population reporting to the hospital and not the community as a whole. Most of the patients had similar smoking or tobacco chewing habits," he said.
