Jaw cancer
Introduction
Introduction to Jaw Cancer Malignant tumors of the oral and maxillofacial regions are most common with cancer, and squamous cell carcinoma is the most common in cancer. In China, oral and maxillofacial squamous cell carcinoma often occurs between 40-60 years old, more men than women, with gingival cancer, tongue cancer, cheek cancer, sputum cancer and maxillary sinus cancer, and jaw cancer is relatively rare. Oral cancer is in the north of the Yangtze River in China, accounting for 1.45-5.6% of systemic malignant tumors, 1.75-5.18% south of the Yangtze River. In India, it is more than 40% in systemic malignant tumors. Jaw cancer mainly occurs in tooth germ glazing. The remaining cells of the epithelium, which may remain in the periodontal ligament, cyst lining, and malignant transformation from enamel cell tumors, which may be squamous or glandular epithelial cancer in histological type. basic knowledge Sickness ratio: 0.0001% Susceptible people: good for men between 40-60 years old Mode of infection: no specific population Complications: oral cancer oral disease
Cause
Cause of jaw cancer
Infection factor (24%):
The cause of bone cancer may be related to infection. Experts point out that bone cancer can occur at the site of a fracture or infection. Exposure to specific carcinogens, such as chemicals such as dyes or coatings, may increase the risk of bone cancer. Therefore, friends should pay attention to the care of the wounds in daily life to avoid the occurrence of bone cancer due to infection.
Endocrine factors (24%):
The cause of bone cancer may also be related to the development of endocrine. Experts say that the age of onset of bone cancer is 15 to 24 years for men and 5 to 14 years for women. Its occurrence may be related to the growth and endocrine development of different genders, and the need to pay attention.
Genetic factors (20%):
The occurrence of bone cancer may also be related to genetic factors. Experts point out that there are some chromosomal abnormalities and a few rare genetic-related diseases associated with bone cancer that require attention.
Chemical pollution (15%):
Experts believe that some high doses of radiation and certain chemotherapeutic drugs, especially those called alkylates, may be associated with the causes of certain types of bone cancer. Therefore, the occurrence of bone cancer may be related to chemical pollution.
Prevention
Jaw cancer prevention
The etiology of oral cancer has not yet been fully understood, but the current consensus is that most oral cancers are related to environmental factors. Some external factors, chronic damage, ultraviolet rays, X-rays and other radioactive substances can become carcinogenic factors.
In addition, internal factors such as neuropsychiatric factors, endocrine factors, immune status and genetic factors of the body are found to be related to the occurrence of oral cancer. Therefore, the prevention of oral cancer is to reduce external stimuli, improve the body's disease resistance, and maxillary sinus. Like cancer, the early diagnosis of jaw cancer is difficult, and it is often confused with alveolar abscess, mandibular osteomyelitis and neuritis. Therefore, be sure to be highly vigilant, perform necessary auxiliary examinations such as taking pictures as soon as possible, and remove one if necessary. Pathogenic teeth, scraping a piece of tissue from the alveolar socket for pathological examination. In addition, the preferred surgical treatment of this disease, radiotherapy or chemotherapy treatment can help improve the treatment rate, but the latter two can not be used as the main treatment. In order to avoid delay in treatment, it is even more difficult to use some prescriptions for external application, stimulate the growth of tumors, delay treatment, and even lose treatment opportunities.

It can be transferred to the submandibular and deep cervical lymph nodes, or it can be transferred to the lungs with a poor prognosis.
Symptom
Jaw cancer symptoms Common symptoms Toothache teeth loosening and shedding of lower lip numb molars
1. Occurs in the mandible, especially in the mandibular molar area. There is a solid mass in the affected part, which grows rapidly. There is no ping-pong feeling in the percussion, and there may be tenderness.
2. There may be toothache, local pain, and invading the inferior alveolar nerve may cause numbness of the lower lip.
3. Invading the alveolar process may cause loosening of the teeth, shedding, and the tumor protrudes from the alveolar socket. When the adjacent masticatory muscles are invaded, the mouth may be restricted.
4. Regional lymph node metastasis may occur.
Examine
Jaw cancer examination
1. For clinical manifestations, the tumor is more limited than the ones to check the project to check the box limit "A".
2. For the atypical clinical manifestations, the differential diagnosis is more difficult, and the larger the tumor is closely related to the surrounding important structure or the suspected metastatic examination project may include the check boxes "B" and "C".
3. X-ray film. Show irregular worm-like damage.
4. Histopathological examination confirmed the diagnosis.
Diagnosis
Diagnosis and diagnosis of jaw cancer
diagnosis
Diagnosis can be performed based on clinical manifestations.
Differential diagnosis
1. Chronic jaw osteomyelitis has a history of inflammatory disease. X-ray films show bone destruction and repair of periosteal hyperplasia. When clinical and X-ray can not be identified, frozen sections should be taken during surgery to exclude central jaw cancer.
2. Neuritis is relatively rare, numbness is light and heavy, X-ray examination without bone destruction.
3. X-ray of central mandibular hemangioma showed a trumpet-like change in the mandibular opening and enlargement of the mandible.
4. Alveolar abscess has lesions and local redness and heat pain dysfunction, but no numbness of lower lip.
