I'm not very good at math, but I'm reading that as a 0.7% increase in your chance of getting cancer. From 'Physics for Future Presidents', they say it is commonly accepted that we have a 20% chance of DYING from cancer before calculating for outside influences. http://books.google.com.au/books?id=6DBnS2g-KrQC&pg=PA98&lpg=PA98&dq=physics+for+future+presidents+cancer&source=bl&ots=_0qSSAxozw&sig=mGZEYJPaciupf-a7ZUCS_HIEhac&hl=en&sa=X&ei=XZvtUqnqNsmZiQfq8IDQAQ&ved=0CCYQ6AEwAA#v=onepage&q=physics%20for%20future%20presidents%20cancer&f=false http://books.google.com.au/books?id=6DBnS2g-KrQC&pg=PA98&lpg... Let's say the average person does not get a CT scan every year for 20 years, but rather gets 5 scans over their lifetime. Those scans may detect an early stage of cancer, therefore saving the persons life. They're risk of dying from cancer is approximately 20.2%. I suggest with the CT scan, their still coming out on top.
