Oral cancer is a malignant tumor that occurs in the oral cavity and has a great impact on patients. Oral cancer is a general term for malignant tumors in the oral cavity, including oropharyngeal cancer, tongue cancer, gum cancer, jaw cancer, lip cancer, and so on. As we all know, many tumors are easier to be treated in the early stage, so let’s take a look at what are the early symptoms of oral cancer. Five signs foretell oral cancer, you should know. 1. Pain There will be pain in the early stage, especially the local friction, but there will be obvious pain after the tumor is broken, and it may also spread with the ear and throat. If the oral mucosa becomes white, brown or even black, it is a sign of the beginning of the disease and should be taken seriously. 3.Lymph node enlargement Oral cancer will generally move to the lymph node area, so the enlargement of lymph node should be taken seriously, and metastatic cancer cells will appear in the lymph node area. 4.Dysfunction The opening and closing movement of the patient will be affected because the tumor invades the muscles of opening and closing and the jaw joint. 5.Uncured ulcers Oral ulcers are common to many people, but it does not mean that ulcers in the mouth means oral cancer, but if the ulcers do not heal for a long time, it may cause oral cancer. Once you have cancer, what are the treatment methods? The basic treatments include surgery, radiation therapy, chemotherapy and herbal medicine. If it is early stage oral cancer and there is no metastasis of cancer cells to the lymphatic area of the neck, then surgery or radiation therapy alone can be used, both of which have very good results. If the oral cancer is already in the middle or late stage, then it is more suitable to undergo surgery and post-operative treatment with radiation. How to prevent oral cancer?
