@Bear1966 - I am so sorry you are going thru this - it is not the news you really wanted to hear. I hope you have a strong family & friends to support you.
Do you have a breast care nurse that you can contact to chat with re any concerns that you have? Or maybe, ring our helpline on Monday?
1800 500 258.
Take plenty of deep breaths, try & keep yourself busy doing stuff you like (I went fishing every day!) to keep you distracted. xx. take one day at a time & try not to get ahead of yourself.
All the best for your PET scan next week. Take care
