Bone tumor is a tumor that occurs in bone or its affiliated tissues. There are benign and malignant bone tumors, benign bone tumors are easy to cure and have a good prognosis, while malignant bone tumors develop rapidly, have a poor prognosis and a high mortality rate. Bone tumors: insidious onset, great harm Clinically, there are three types of bone tumors are more common, benign bone tumors, malignant bone tumors, and one is metastatic bone tumors. Benign bone tumors are slow growing and generally do not have obvious symptoms, most patients are due to occasional radiographs found that not all benign tumors require surgery. Since most benign bone tumors do not affect human health, they do not need to be “eliminated”, or else they will be over-treated. The decision to operate or not should be based on the tumor condition, growth site, size and age of the patient. However, if a benign bone tumor is found to have the possibility of malignant transformation, or if it grows to a large extent and compresses the surrounding nerves and blood vessels, and the patient experiences compression symptoms, then surgical treatment is needed. Like benign bone tumors, malignant bone tumors are often not taken seriously by patients, but the harm they cause is enough to destroy a life or even a family. Malignant bone tumors develop rapidly and can have multiple metastatic foci, with lung metastasis being the most common. The most common malignant bone tumors are osteosarcoma, Ewing’s sarcoma and chondrosarcoma. In terms of the age of disease, there are two peak stages, the first peak is under 20 years old, about 1/2 of the primary malignant bone tumors occur in this age group, especially osteosarcoma is the most common; the second peak is after the prime of life, mainly metastatic bone tumors. Metastatic bone tumor is a kind of secondary tumor which is mainly caused by malignant tumors occurring in other parts of the body transferring to bones and growing through various ways. In this regard, if middle-aged and old people have frequent bone and joint pain, and suspicious bone destruction is found through radiographs, the possibility of metastatic bone tumor should be highly suspected. Since most of the patients with metastatic bone tumors are in the advanced stage of the tumor, palliative treatment is often adopted to prolong the patients’ life, reduce the pain and improve the quality of life. Once you find that you have limb, bone and joint pain, and long-term symptoms are not relieved, and even the appearance of nocturnal pain, you must be vigilant, timely medical care! Treatment of malignant bone tumors: breaking the dilemma of “losing the car to protect the commander-in-chief” Pain is a major manifestation of bone tumors, and its early symptoms manifested as unexplained pain in the limbs, and progressive aggravation of pain at night. The early symptoms are unexplained pain in the limbs and progressive aggravation of the pain at night. Once a teenager has such a condition, it is often mistaken for growing pains by the parents or doctors, thus delaying the early detection and treatment of bone tumors. Whenever a child complains of nocturnal pain, it is important to pay close attention to it and do relevant examinations, sometimes an X-ray can confirm the diagnosis. However, for children who are highly suspected of having a bone tumor, and the site of occurrence is in the pelvis, spine and other locations that cannot be well shown by X-ray, it is necessary to do a magnetic resonance examination to rule out the existence of bone tumors. Due to the aggressive condition of malignant bone tumors, most clinical treatments in the past adopted the method of “losing the car to save the head”, i.e. amputation of the affected limb. Most patients with bone tumors are faced with only two choices: death or disability. This will undoubtedly cause great psychological and physical trauma to the patient. Treatment: At present, for the treatment of malignant bone tumors, the clinic mainly adopts surgery as the main treatment, supplemented by radiotherapy and chemotherapy as a comprehensive treatment means. The premise of limb preservation is also to carry out chemotherapy first, and after effectively controlling the tumor, carry out tumor resection surgery. However, since tumor resection often causes tissue defects, artificial prosthesis replacement is often needed after resection to rebuild the patient’s limb function.
