What are the early and late symptoms of bone cancer?

What is bone cancer? Bone is the scaffold of the human body, which produces important tissues in which the human body participates. Although bones account for an important part of the body, almost all bones can be seen on every X-ray, but few bone cancers are found by accident. Like other organs, the skeletal system will suffer from tumors from any tissue components or metastatic lesions from other organs. Tumors invading bone can occur in bone cells, hematopoietic components of bone, cartilage and fibers or synovial components. Other tumors may come from musculoskeletal nerves, blood vessels and adipose tissue. Osteoma can be divided into benign osteoma, low-grade malignant osteoma and high-grade malignant osteoma. Benign osteoma is not fatal to human body, while malignant osteoma with abnormal cancer cells is fatal to human body and will be transferred to other tissues and organs. Benign osteomas sometimes turn into malignant bone cancers. The real cause of bone cancer is not clear, but it may be related to bone overgrowth, chronic inflammatory stimulation, metabolic problems and radiation. Pathological types of bone cancer include multiple myeloma, osteosarcoma, soft tissue sarcoma and fibrosarcoma. However, the most common symptom of malignant bone cancer is metastasis to bone, especially in the spine and pelvis. The most important thing to diagnose osteoma is to distinguish it from benign, low malignant and high malignant, which is closely related to the age, sex and location of the disease. Therefore, it is necessary to rely on the cooperation of patients, orthopedic surgeons, radiologists and pathologists to make the most correct diagnosis at an early stage and achieve the best treatment effect. The reasons may be related to bone overgrowth, chronic inflammatory stimulation, genetic factors, special virus infection, poor blood circulation in bone and radiation exposure. The age, sex and location of the patient are very helpful for the differential diagnosis of osteoma. Bone cancer is common in young people aged 12 ~ 20, with primary osteoma being the most common, followed by metastatic bone cancer and multiple myeloma aged 50 ~ 60. Clinical symptoms are the same as those of other cancer patients, such as loss of appetite, weight loss, fever and so on. Pain in the affected part, local lumps and swelling in joints and limbs. The joint and limb movements of the affected part are limited. The skin of the affected part is ulcerated. The distal end of the affected limb will be numb due to compression of nerves and blood vessels. Pathological fracture or deformation occurs. The most typical symptom of bone cancer is bone pain. If bone pain is more obvious at night than during the day, you should pay special attention. How to diagnose clinical symptoms and medical history? Routine physical and biochemical examination. Radiological examination: General X-ray photography, angiography, lymphangiography and other examinations can be performed on the affected bone, and differential diagnosis can be made between malignant osteoma and benign osteoma according to the imaging properties of the photos. The reliability can reach 90% for experienced radiologists, especially computed tomography, magnetic resonance photography, angiography and nuclear medicine bone isotope scanning, which is faster and more convenient. Pathological examination is divided into three methods: 1 needle sampling examination, and its success rate is 80 ~ 90%. 2. Incision and sampling of the affected parts. Pathological examination of excision or curettage: histopathological examination is the final correct diagnosis made by pathologists according to the pathological transformation of sliced tissue. How to treat surgical treatment: 1 simple excision 2 eradication plus bone grafting 3 amputation.
