Thanks for your reply & hope all goes well for your mom. My heart goes out to her! From what I've read it sounds like her experience is fairly typical in chest radiation patients - lots of complications that they don't see beforehand. And after the surgery healing is slow. Invasive surgery is not really advised for people like us, but there isn't yet a procedure like the TAVR( for aortic valves) for the mitral valve.
Did your mom have her incision through the sternum or the ( supposedly less invasive) smaller incision on her right side?
From things I've read, recovery, even for those with no complications, can be very long & hard. Your mom has really been dealt a blow, I wish her all the best. Please let her know a fellow cancer survivor is rooting for her. I so much appreciate your reply & I would love to hear how things go for your mom, please keep us updated...
