(Standard) breast cancer radition increases cardiac disease by 7.4%
Interesting. With Axxent, should be that less x-ray reaches the heart and a shield can protect senstitve areas. If radiation treatment were like a drug, it would not get past the cardiac safety panel...

Undergoing radiation treatment for breast cancer could lead to significantly increased risk of later developing ischemic heart disease, says a new study from researchers at the Clinical Trial Service Unit in Oxford, England.
For the study, the research team reviewed health records from 2,168 breast cancer survivors in Sweden and Denmark. Overall they found that for every unit of radiation exposed to the chest there was a 7.4 percent increased risk of developing heart disease.
"Clinicians may wish to consider cardiac dose and cardiac risk factors as well as tumor control when making decisions about the use of radiotherapy for breast cancer," lead researcher Sarah Darby writes in her study report.
Peer reviewer Dr. Jean-Bernard Durand, MD, of the MD Anderson Cancer Center in Houston adds:
"We have to be extra vigilant with women, making sure we assess them. We make sure they're on correct medicines and we make sure they gain all of the benefits from surviving breast cancer."
