Cause
Epidemiological studies are required to determine risk factors.[1] Aside from exposure to vinyl chloride or ionizing radiation, there are no known environmental factors associated with brain tumors. Mutations and deletions of so-called tumor suppressor genes, such as P53, are thought to be the cause of some forms of brain tumor.[2] Inherited conditions, such as Von Hippel–Lindau disease, multiple endocrine neoplasia, and neurofibromatosis type 2 carry a high risk for the development of brain tumors.
Although studies have not shown any link between cell phone or mobile phone radiation and the occurrence of brain tumors,[3] the World Health Organization has classified mobile phone radiation on the IARC scale into Group 2B – possibly carcinogenic.[4]
