@Annaspanna My name is Rosie and I'm one of the Cancer Nurses working on the BCNA Helpline.We also moderate the online network discussion. You've already had some great advice from people are speaking from experience and truly know what you are going through. It also sounds like your Breast Care Nurse will be a great support. With regard to your question about taking supplements I would suggest you look at the US based Memorial Sloan Kettering Cancer Centre website about Herbs https://www.mskcc.org/cancer-care/diagnosis-treatment/symptom-management/integrative-medicine/herbs
You can look up the latest evidence based information about all sorts of supplements and treatments you might hear of and find out what is known about how they work in cancer. BCNA also has a fact sheet on the website called Beware Dr Google that you can order or download for reliable sources of information
