Bone cancer Overview

Occurred in the skeletal system, where a variety of organizations such as bone, cartilage, fibrous tissue, adipose tissue, hematopoietic system, nervous tissue and undifferentiated reticuloendothelial structures are of primary tumor arising from bone tumors. By direct infiltration, blood circulation or transfer of the lymphatic system in the bone metastases within the organization for the formation of secondary bone tumors. Apart from benign bone tumors, malignant exceptionally, there are part of the bone tissue within the lesion can not be certain whether the nature of true bone neoplasms, such as fibrous dysplasia, solitary bone cyst, eosinophilic granuloma of bone, bone Class lipid metabolism disorder psychosis, saying that tumor-like lesions (bone tumor-like lesions).

     The cause of bone tumors are still not clear, in the past that the injury, especially chronic minor injuries, chronic infection can cause bone tumors. In recent years, through the experimental study, such as Fujinaga has used Harvey and Moloney sarcoma virus produced a large number of mouse osteosarcoma model, Finkel has used different types of isotopes and viruses made of animal model of osteosarcoma, some people use of radioactive substances such as radium, strontium and other manufactured Animal model of osteosarcoma. These pathogenic factors have been identified by many scholars. Age of onset of bone cancer for males 15 to 24-year-old female is 5 ~ 14 years of age may be related to different gender bone growth and endocrine development and duration of the morning and evening.
