I was diagnosed in April with IDC (ER+|PR+ HER2-)and had 2 unsuccessful lumpectomies followed by a unilateral mastectomy with immediate implant reconstruction on July 1st last. My oncotype score was 13 and as the mastectomy had clear margins I thankfully don’t need either chemo or radiotherapy. As my cancer was ER+ I now need to start tamoxifen. My question is have any of you ladies delayed starting tamoxifen by a few weeks? I have a much needed holiday booked for the first two weeks of August & ideally want to start on my return which would be 6 weeks post mastectomy. Am I taking a big risk by doing this? Any advice gratefully appreciated. Thank you.
