Hi Debi, that must have been a terrible shock to find out, especially so soon after finishing treatment. As Brenda said there are many people living with secondary breast cancer and the treatments are improving all the time. You might be interested in contacting BCNA's telephone counselling service (1800 500 258) to talk to trained counsellors about your situation and to ask questions (secondary-breast-cancer-telephone-support). BCNA also has lots of useful information and resources that might help - the Hope and Hurdles Kit may be a good start for you. You might also be interested in joining the Living with advanced / secondary breast cancer group on this site (click here) to connect with others that may be having similar treatments to you.
Wishing you all the very best with your treatment. Hugs, Jane xx
