An additional younger-age peak for cancer of the nasopharynx.
The age distribution of 666 masopharyngeal cancer patients attending the Tata Memorial Hospital, Bombay, during 1941-72 was found to show an additional younger-age peak in the age-group 13-22. The peak was found in both sexes, in different communnities, at two time periods and in histologically proved cases. One hundred cases of nasopharyngeal lymphosarcoma showed no deviation from a uniform age distribution. Pooled incidence data for 48 population groups showed the peak in the age-group 15-19 for males and in the age-group 10-14 for females. No such peak was observed for malignancies of the nose, sinuses, etc. (ICD NO:160)
