Did they say what tumors they were seeing in excess in women?  Of course, my first guess is breast Ca.

 Abstract 17486 — Radiation exposure from cardiac imaging after heart attack 
more likely to cause cancer in women than men 

Women who have had a heart attack, regardless of age, face a higher risk of 
cancer associated with exposure to low-dose ionizing radiation from heart 
imaging procedures than male heart attack patients. 

  
Researchers measured the effects of age and gender on low-dose ionizing 
radiation-associated risk of cancer in heart attack patients who had been 
exposed to the radiation from cardiac imaging procedures. Studying a database of 


56,606 male and 26,255 female heart attack patients between 1996 and 2006 in 
Quebec, they found: 

    * For women, the median age was 71.7 years, low-dose ionizing radiation 
exposure was 3.7 millisieverts (mSv) per year, and 3,545 new cancers were 
observed over 4.2 years. 

    * For men, the median was 59.7 years, low-dose ionizing radiation exposure 
was 

4.1 mSv/year, and 8,475 new cancers were observed over 4.8 years. 

    * The interaction between gender and low-dose ionizing radiation was 
significant, but it wasn't between age and low-dose ionizing radiation. 

    * For every 10 mSv increase in low-dose ionizing radiation, the risk of 
cancer 

increased by 4.4 percent in womem and 2.1 percent in men.
