Hi Danielle,
My oncologist also is concerned about the extra radiation from scans, but I request to have one every year.
As it was, I found a lump in my second breast prior to my scan which did turn out to be another cancer and am now in treatment again. They also brought my scan forward to make sure I did not have any secondaries.
I think it is only natural to want to have whatever checks may help to find any signs of problems as early as possible and the doctors and specialists need to support the patient in whatever makes us feel comfortable. It is our body, our treatment, our health, our lives and therefore it is our choice.
Good luck with it all.
Cheers,
Nenie
