I have had two head/brain ct scans, can that cause brain tumor?

highly unlikely: It is highly unlikely that the amount of radiation that you were exposed to during 2 ct scans will have any harmful effect at all. http://www.news-medical.net/news/20130531/mayo-clinic-experts-provide-some-insight-about-radiation-dose-from-ct-imaging.aspx.

Not likely: While in theory any radiation might cause a tumor, the amount of radiation in a diagnostic ct scan is highly unlikely to lead to a brain tumor.
