MUGA variation question

[janet11]

I've had 3 MUGA scans:
September (pre-chemo): 63%
December (almost at end of chemo(TCH)): 60%
March (after 3 months more of Herceptin every 3 weeks): 53%

I just got that last result this morning. So they're doing another scan in 6 weeks (instead of waiting 3 months). Has anyone had a drop like this, then had it go back up? I'm not having any symptoms of heart problems, and I've actually had so FEW serious problems from treatment that I was surprised at the result.

Would exercise help? I promise, I'll go back to the gym (*smile*) if it'll help me stay on my treatment plan. I should have asked my onc today about this, but figure that the "good sense rule" would be what I should follow anyway (in other words, do it, but don't overdo it). Hmm... guess exercise wouldn't hurt. Drat.

After re-reading the above, guess I don't have a real question other than wondering if there's some hope that the drop will level off without having to stop Herceptin. And that won't be answered until my next scan(s). So guess I really just wanted to gripe a bit. Sorry (*smile*).....
