Haven't had radiation but after chemo and still on Herceptin and Femara I went to 6 monthly checks with my oncologist and my surgeon - so I saw one of them every 3 months. Now (nearly 5 years) I only see them each yearly and I suspect that may reduce/end but only if all goes well in October (fingers crossed!). I can also see either if I feel I need to - three times with my surgeon, partly due to an intractable seroma, but never with my oncologist.
