Heart Disease Risk Linked with Breast Cancer Radiation
(Ivanhoe Newswire) –In 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 at Columbia University Medical Center, N.Y.
Researchers studied the radiation treatment plans of 48 patients with stage 0 through IIA breast cancer. They calculated the link between radiation treatment factors, like mean cardiac risk, body positioning, treatment side, and coronary events.
They discovered that the highest coronary risks were 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.
