Diagnostic features of malignant bone tumors include rapid tumor growth, severe pain, bone destruction, susceptibility to pathologic fracture, and early susceptibility to hematogenous metastasis. Malignant bone tumors have a higher degree of malignancy, so the tumor grows faster.
Malignant bone tumor has higher malignant degree, so the tumor grows faster.
Malignant bone tumors with localized lesions in the bone area will have severe pain symptoms, and the pain leads to the patient’s activity limitation.
The imaging examination of the tumor suggests severe bone destruction leading to osteoporosis, and there will be obvious periosteal reaction around the bone.
Osteoporosis is obviously prone to fracture and localized deformity of bone may form.
Malignant bone tumors are prone to hematogenous metastasis at an early stage. Lung and liver are the common sites of metastasis.
