how many xrays per year make you vulnerable to cancer?
Question:
Answers:
Good question.
First of all, everyone has a one in three chance of developing cancer regardless of any sort of external exposure.
Secondly, x-ray frequency is as important as x-ray location in determining the very slight increase in risk.
A credible British study published in the January 2004 Lancet medical journal attributed six tenths of one percent of all cancers to x-ray exposure.
Essentially, most standard x-rays expose you to a few days or a few weeks worth of the background radiation that you're already exposed to. X-rays dramatically increase in radiation exposure as you get into CT scans and fluroscopies, with the most radiologically significant scans being worth up to a few years worth of background radiation exposure.
The most significant is an isotope bone scan, which carries a 1 in 1000 risk. Each additional scan would add to this risk, but considering that your starting risk is 1 in 3, it's not going to be a significant increase. I would think that anyone at the point of needing multiple advanceds scans stands to gain much more by going through the scan than by passing it up for fear of cancer.
