I am so sorry for all your worry. I didn’t realize you had cancer. I’m so so sorry. Could the soreness be scar tissue? You should be given answers. My mom had breast cancer as well and she had to follow up with the specialists until years later. Maybe you could go to the primary care and ask for a breast exam? I know it isn’t expediting the specialists job, but if they feel something, that doctor can call the other doctor on your behalf. If that is not something you can do, perhaps you could go on the patient portal. It sounds like you need to bypass the nurse. Maybe you could be put on the cancelation schedule in case someone cancels and you could take their place? Patient portals are good to use. Most doctors respond. Maybe put a note this way the doctor is on notice. I would try the pcp and to call and ask to speak to the doctor. Are you having any discharge, dimpling, pea sized felt? I’d be ticked at that unreassuring nurse. That nurse should be aware of what cancer patients endure and react appropriately, not dismissively. I’d try to bypass the nurse and speak directly with the doctor. I wish I had more helpful advice for you. 🤗
