Specific analysis of the causes of bone tumors

The etiology of bone tumors is very complex. Generally speaking, the internal factors are present first, and the external factors occur through the internal factors. The internal factors include the quality theory, the gene theory, the endocrine theory, etc.; the external factors include the chemical elements, the chronic stimulation theory of internal and external radiation, the virus infection theory, etc. The following is a detailed analysis of the etiology of bone tumors.
