Now What?

If you look at the statistics on recurrence following herceptin, I believe it peaks at around 2 years and then falls off dramatically, so your doctor is correct (of course!). I know it is hard to accept that you will not be tested constantly, but the tests will not prevent recurrence (if it happens - and you will most likely not have one) and the detection at 6 months would be sufficient. Of course if you notice anything you should contact your doctor. It is hard to go from constant treatment and monitoring to nothing - a lot of patients feel anxious about it (being on their own) - but it gets easier with time.
