Introduction
Chewing betel nut may lead to oral mucosal lesions, such as oral submucous fibrosis, which is considered an early precancerous lesion. Therefore, long-term betel nut use, especially prolonged retention in the oral cavity, may allow carcinogenic substances to accumulate in the body and trigger malignant transformation. Given this, a patient who has chewed betel nut for five years has a relatively high risk of developing oral cancer and should remain highly vigilant.
Chewing betel nut for five years may lead to oral cancer.
Betel nut has long been classified by the World Health Organization as a Group 1 carcinogen. This is primarily because long-term betel nut chewing often leads to oral mucosal lesions, such as oral submucous fibrosis, which is considered an early-stage malignant change. Such conditions can result in restricted mouth opening, difficulty swallowing, and impaired tongue movement. Continuous consumption of betel nut and its prolonged retention in the oral cavity may cause accumulation of carcinogens in the body, thereby triggering cancerous changes. Therefore, individuals who have chewed betel nut for five years face a significantly increased risk of developing oral cancer and should remain highly vigilant.
If, after chewing betel nut, a person develops white or red patches on the gums, tongue, or oral mucosa, or experiences oral ulcers that persist for more than three weeks without healing, it is advisable to promptly visit a hospital for appropriate examinations to determine whether oral cancer has developed. When necessary, under medical guidance, surgical treatment or systemic therapy may be used to timely remove the primary lesion, minimize damage, and prolong survival as much as possible.
