A few years ago i had a face xray due to a broken nose. do i have to worry about brain cancer now? seeing as there was radiation on my head from xray

Relax!: We are exposed to radiation every day. There's a lot in the environment. Some places have more than others too. X-rays & other imaging studies, are very safe, unless many are needed in your life. It is always wise to ask before any x-ray what the alternatives are. Your risk for cancer is higher with a high protein, or high fat diet, if you drink alcohol regularly, smoke, or don't wear sunscreen!
