Question: are brain cancer rates increasing?
Answer: 1) Brain cancers are rare. In the US, the incidence (that is, the number of newly diagnosed cases per year per 100,00 population) of all brain cancers is 6 cases per 100,000. (By contrast, the incidence of breast cancer is 125 per 100,000, and that of prostate cancer is 120 per 100,000).
