These are all cancers, not radiogenic cancers.

****************************************** 
In women 3.7 mSv per year caused 3,545 cancers in 4.2 years among 26,255 female patients. That is an incidence of 13,5% in just 4.2 years from a trivial annual dose. 
 
THE FINDINGS AND CONCLUSIONS OF THIS STUDY ARE CONFUSING AND UNBELIEVABLE.
