Hi Sue
Have you changed treatment centre from your original diagnosis?
All these tests are necessary to set the benchmark before treatment so they can measure the effectiveness of the chemotherapy/targeted treatment. The gated heart test is to establish that your heart is strong enough to undertake the Herceptin treatment
Have you been on on-going Herceptin or is this a new targeted treatment for you?
Can't help with the hot flushes, didn't get them at menopause, and haven't had them on my latest treatment of Tamoxifen, even though I was told I would.
For post menopausal women the main side effect of Tamoxifen that we have to watch out for is blood clots, usually in the legs.
With love
