Gingival cancer is cancer that occurs in the mucous membranes of the upper and lower molars. Mandibular gums occur clinically. The authors treated 97 cases of oral malignant tumors confirmed by pathology from April 1976 to April 1990, including 18 cases of mandibular gingival cancer. The review of the literature on the relationship between the degree of morbidity, the degree of jaw involvement, and the post-jaw relationship is presented below. Clinical data in this group of 18 cases, 10 males and 8 females, male to female ratio was 1.25:l. The onset years were 37 years old and 78 years old, with an average of 63.5 years. In this group of cases, the incidence was highest in the 60-69 age group; it accounted for 44.4% of the total (Table 1). There were four symptoms within one month, seven cases from two to six months, three cases from July to December, and four cases from one year or more.
