Chest wall infiltration: Chest wall tumors generally refer to tumors of the deep soft and skeletal tissues of the chest wall. Chest wall tumors can be divided into two categories: primary and secondary. Secondary chest wall tumors are mostly caused by the metastasis of malignant tumors from other parts of the body to chest wall tissues, or direct infiltration of malignant tumors of lung or pleura adjacent to the chest wall. Primary chest wall tumors are rare, accounting for about 5-10% of the primary tumors in the whole body. 80% of them occur in the ribs, most of them are benign, and about 20% occur in the sternum, while tumors in the sternum are more malignant. Rib tumors occur in the anterior and lateral chest wall, and are less common in the posterior chest wall. What are the prevention methods of chest wall infiltration? 1.Rational rest, patients can carry out general activities, but rest can lower the basal metabolic rate and reduce the consumption of oxygen, so it is necessary to arrange rest reasonably. 2, encourage patients to drink more water, eat more vegetables, fruits and other vitamin-rich foods. 3.The diet should be given high-calorie, high-protein, nutritious and easy-to-digest food to replenish the heat consumed due to the hyper-metabolism of the body. The prognosis of high degree lesions is worse than that of low degree lesions rhabdomyosarcoma has the best prognosis and malignant fibrous histiocytoma has the worst prognosis. Chest wall tumors, whether benign or malignant, should be surgically removed. Metastatic tumors of the chest wall should also be surgically removed if the primary lesion has been removed. If malignant tumor is not excluded, it should be treated as malignant tumor. When removing a large tumor, the chest wall defect should be repaired to prevent the formation of abscess chest and abnormal breathing. After removal of malignant tumor, chemotherapy or radiation therapy should be supplemented. Regardless of benign or malignant, surgery is indicated when physical condition permits. The purpose of surgical treatment is to remove the lesion to prevent local recurrence, maintain the integrity of the chest wall, and preserve the function of the chest wall.
