Radiation position reduces CV risk in breast cancer

The highest excess coronary risk (more than threefold) was seen in women with high baseline risk treated for early breast cancer on the left side while lying in a supine position, with the risk being reduced when lying prone, they wrote in a research letter.

The lowest risks were among women at low baseline cardiac risk receiving right-sided therapy.

Radiotherapy-induced risks were likely to be reduced by targeting baseline cardiac risk factors with lifestyle modification or
