Hi Arpie thank you for replying what I was told after surgery my 8 mm tumour was tested and it was slow growing my calcifications near my nipple weren't yet cancerous but they can turn cancerous they were in my milk ducts. I don't have a very good understanding of my calcifications and if it was invasive lobular cancer or not. I found the study on the internet after talking to my radiologist this week. I did ring his rooms and asked for him to send me the information so I could read it again but he hasn't replied yet. So I googled Uk trials on women over 65 with slow growing cancer and radiology. I found Prime study 2 it must be the study he showed me on Monday, it was posted on 24/2/23 it came from the New England Journal of medicine and also another site Esmo has posted the same findings. The title on one web sites that published the study is breast conserving surgery with or without irradiation in early breast cancer. On the Esmo site its sub title is radiotherapy can be safely omitted in older women with low risk Hr positive early breast cancer treated with adjuvant endocrine therapy. My radiologist said he would give me radiotherapy going through the side of my breast im not sure what position I would be laying in. There was no mention of specific breathing for me with mine being left breast. I am seeing my oncologist next week to start on Endocrine therapy again. I found the only thing I got was constipated while taking it when my surgery was delayed.
