Gift,
We have looked at using Co-Q10 win conjunction with breast cancer treatment especially with Aredia due to cardiac toxicity. Studies have not confirmed its efficacy in this arena and the benefit/risk of adding a strong antioxidant during chemo is also not entirely clear. Because of this we tend to recommend adding Co-Q10 for women on a treatment break (sometimes due to low MUGA score). Here are a few article links from pubmed.gov. Many suggest further research is needed due to small size of the studies.
