Tumours of the Respiratory Tract
The frequency of tumours of the respiratory tract show well marked differences from other countries. Nasopharyngeal tumours and carcinoma of the maxillary antrum are commonly seen, whereas tumours of the larynx and lung are rare. Nasopharyngeal carcinoma is poorly differentiated, occurs at a young age and is found more commonly in patients from the north of the country. Tumours of the nasal sinuses occur in older people and do not appear to be related to snuff taking. Adenocarcinoma of the bronchus accounts for a slightly greater proportion of cases than where tumours of the bronchus are more common. There is as yet no indication of a rise in the incidence of bronchial cancer.
