It is not inocuous - to have those scans ( apart from MRI I guess). I was told not to hold a baby on my lap for a couple of days after either bone scan or CT scan - I don't remember. And when I compare radiation received from a intraoral dental radiogram to CT scan - CT scans produce hundreeds thousands times more radiation.
Oncologist told me initial staging CT and bone scans find methastasis in only 5% of women with stage 3, and as far as I remember about 30% of us will develop them in either 5 year time or 10 year time. It does meen the disease is still undetected in majority of cases. I don't know, probably PET is more sensitive and statistics for it are different.
