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.
