At this dose, approximately 6391 people would have to be exposed to cause 1 case of brain cancer. [8] Ionizing radiation to the head as part of treatment for other cancers is also a risk factor for developing brain cancer. [24] Mutations and deletions of tumor suppressor genes, such as P53, are thought to be the cause of some forms of brain ...

[4] The most common sites of primary cancer which metastasize to the brain are lung, breast, colon, kidney, and skin cancer. Brain metastases can occur months or even years after the original or primary cancer is treated.
