Well, this study does not bode well for the hundreds of thousands of women who have faced radiation therapy for their breast cancer. I think anyone facing this treatment in the near future – should be taking this article/study reported by the American Medical Association (AMA) to their doctors. Please share this with other women. Not only have they been traumatized by breast cancer and the ensuing treatments, but now more danger lurks down the road.
Heart Disease Risk Appears Associated With Breast Cancer Radiation
October 28, 2013
Among patients with early stages of breast cancer, those whose hearts were more directly irradiated with radiation treatments on the left side in a facing-up position had higher risk of heart disease, according to research letter by David J. Brenner, Ph.D, D.Sc, of Columbia University Medical Center, New York, and colleagues.
Several reports have suggested links between breast cancer radiation and long-term cardiovascular-related deaths, according to the study background.
Researchers examined the radiation treatment plans of 48 patients with stage 0 through IIA breast cancer who were treated after 2005 at the New York University Department of Radiation Oncology. They calculated the association between radiation treatment factors, such as mean cardiac dose, cardiac risk, treatment side, body positioning and coronary events.
According to study results, the highest coronary risks were seen for left-sided treatment in women of high baseline risk treated in the supine (lying down, head facing up) position. The lowest risks were for right-sided treatment in low-baseline risk women. In left-sided radiation, prone (lying down, facing down) position reduces cardiac doses and risks, while body positioning has little effect in right-sided therapy (where the heart is always out of field).
