I’m being advised to give my 3 year old daughter a PET scan, it’s for genetic information rather than anything to do with cancer.
She has a rare genetic mutation and I’m extremely concerned about giving her radiation.
I read that it’s basically the equivalent of 3 years worth of atmospheric radiation, which would mean that at age 3 she would be given her entire lifetime so far worth of radiation.

Please help allay my fears, I would do this if her life was at risk but it’s not.

I had invasive lobular breast cancer and I also have Bcell Non Hodgkin’s lymphoma in my bone marrow . I just finished 4 courses of two kinds of Chemo therapy 4 weeks ago.
Also diagnosed several years ago with congestive heart failure as I had SOB (ischemia) and thickening of my heart muscle. So in order to be cleared to have surgery (mastectomy) I needed tests of my heart. One of the tests my cardiologist ordered was a CT PET scan.
My insurance just told me 6 months after the fact that test wasn’t needed and they won’t be covering the cost!! Help! Any suggestions?

Why are PetScans recommended before/AFTER RADIATION TREATMENTS within 3-4 months after?

Can PET scans be used to help diagnose other diseases like some Autoimmune diseases? I've had numerous medical problems for decades, with a lot of abnormal blood, urine, x-ray, ect. tests but never have been given a definite DX.

Can a diabetic type 2 and high in cholesterol patient be pet scan or

The short half life doesn't make the radioactive isotope not dangerous. The low dose makes the radioactive isotope not dangerous. All else being equal, a substance with a shorter half life is more radioactive and therefore more dangerous. For example, iodine-131 has a half-life of 8 days and is used to deliberately damage the thyroid gland via radiation burns, whereas bismuth-209 has a half-life of 20 quintillion years and is used to kill bacteria by the oligodynamic effect with no need to worry about radiation.
