Hi Vicki Sounds like they are looking after you well, as Georgina Mary advised you arent too bad. When I was having hercepton my onc advised that sometimes they get a heart doc involved if need be to more closely moniter things - so they have probably got lots of things to try before your heart stops.
I'm not in your boat, but have heard on this site that there are other drugs - is one Perjetta?? But what I'm reading in your comment is that you need to be getting more info from your docs?? Don't finish your appointment until you get some answers - you have enough stress with out worrying about things that probably aren't worth the worry.
