I am sorry @deekay77, it is a shock. I stopped tamoxifen on advice from my oncologist too because of side effects but I was high risk and then started Letrozole after a 6 week break. I was unfortunately diagnosed with mets but Not everyone with a reoccurance has mets. Most reoccurance is treated the same as its a new cancer.
When do you get your pet scan results? Have they biopsied the new spot? Do you know if it's the same pathology as the original cancer?
It is good you reached out here as we can all support you. Keep busy doing what you like to do. The anxiety is understandable. It is scary. Big breaths because you will get this treated and new and better treatments are coming.
Let us know how you go with results. Your in Brisbane as I am. Have you heard about the Choices Program at the Wesley? It's for all cancer patients and you don't have to be treated at the Wesley to attend any of their programs. Hope the link below works or you can google it. Everything they provide is free. It is a charity. Most people who attend have breast cancer. They offer all sorts of things for people going through treatment. They have some things like yoga online.
