Oral cancer poses a significant threat to human life, and it is crucial to detect and treat it early for optimal outcomes. Individuals over the age of 40, especially those frequently experiencing oral ulcers, particularly with symptoms of bleeding and pain, or when there is a growth at the base of the ulcer, should immediately seek hospital examination for timely pathological diagnosis. Early detection followed by prompt surgery, and deciding whether further radiotherapy or chemotherapy is needed based on the severity of the condition, can achieve the best treatment results. Therefore, oral cancer is treatable and can be cured if detected early.
