Dear Dr. Roach: A year ago, I had surgery for bladder cancer, and had a small stroke and pulmonary clot. During this past year, Ive had five CT scans, three chest X-rays and a couple of other scans to diagnose the stroke and clot. I also had some kind of scan in radiology to put in and then take out an IV blood filter. I am having another CT scan to check kidney function and another chest X-ray in May. Now my GP says Im due for a mammogram. How much is too much radiation? I know its cumulative. R.W.
Answer: People get nervous about radiation. Fear of radiation…
