For Those On Herceptin watching your LVEF

[Hopeful]

I am curious as to how many who have experienced a big decrease had radiation to the left breast vs. the right. I have had a 10 point drop over three months with radiation to the left side and 3 weekly Herceptin. Although I chose my radiation center specifically because they were the only facility in my area that could 100% promise me they could keep my heart out of the field, I still think this makes a difference. When I see the topic discussed here, most don't state which side recieved the radiation, so I thought I would ask.

Thanks,

Hopeful
