Premalignant lesions are morphologically altered tissues, more likely to develop cancer. Premalignant lesions are more commonly expressed as a general condition associated with a significant risk of cancer. These lesions can appear in the oral cavity. Oral lichen planus, submucosal oral fibrosis, and leukoplakia are premalignant mucosal lesions that have the potential to become malignant in the oral cavity in the development of oral squamous cell carcinoma. Public health cadres are men or women selected by the community and trained to deal with individual and community health problems to work in close relationship with places of health care. The lack of knowledge from the public about risk factors for malignancy in the oral mucosa makes public awareness and concern for oral soft tissue health low. Low public awareness and concern can lead to increased failures in the treatment of malignancy cases because patients who come to health facilities with malignancy cases are already in the terminal phase so that it is difficult to handle. Health cadres are given counseling and training on how to conduct their own oral cavity examination so that it is hoped that later it can be distributed to the community in each village
