Small but not vanishingly small.  Each one gives a small increased
lifetime risk of a radiation induced cancer.  I think we are talking in
terms of an absolute risk of around 0.01% per shot, but that is an
off-the-top-of-my-head guestimate.

I'm sure I once read a figure somewhere but I really can't remember what
or where.  I know it is tiny compared to the risks involved in cancer
recurrence, but large enough that it would result in thousands of excess
death if bone scans were used for screening the general population.

Glad to see you are looking forward to still being around in the two
hundred and first century.  <g>

I just had one a few weeks back.  I'm trying to remember what my onc said:
I know he compared it to a chest x-ray, but can't recall if it was "about
the same as a chest x-ray" or "less than a chest x-ray".  (Darn chemo brain,
anyway!) Not that that helps, particularly, in either case . . . .

I had one once, can't remember when but post lumpectomy. I don't think it
had any noticeable effect on my health. Going out in the sun is probably
more damaging. It's a useful diagnostica tool and all precautions are taken
to avoid damage.
