ABSTRACT
Cancer of the buccal mucosa ranks fourth in the structure of cancers. Pretumor processes of the buccal mucosa are Bouin's disease, leukoplakia verrucosa, papillomatosis, erosive ulcerative and hyperkeratotic lupus erythematosus and lichen planus, and postradiation stomatitis. Two clinical cases of cancer of the tongue in young men aged 27 years are described. Preventive measures are treatment of pretumor processes in the buccal mucosa, absolute refusal from caustics and from dentures made of different materials, regular check-ups of patients, consultations at specialized oncological institutions with cytological and morphological studies, thorough sanitation of the oral cavity including therapy, surgery, and orthodontic treatment.

A new method for diagnosing human malignant tumors is dealt with, which is based on fluorescence of malignant neoplasms and their adjacent normal tissue. To measure the fluorescence spectra, a fiber optic system and a multi-channel optic spectral analyser have been designed. While analysing the resultant spectra, a greater fluorescence excess was observed in the red wave band in the tumors than in normal tissue. Further investigations are required in order to use the method in question in clinical diagnosis.

The authors review the results of cryogenic treatment of the lower lip cancer and its recurrences in 212 patients for 1973-1989. The technique of cryodestruction is analysed. It is found that the best results were achieved at the disease stage I-II and local cancer relapses after radiation treatment. The responses were also satisfactory in stage III cancer without extensive spread in the region.
