Thanks for your response. I am 3 years into treatment for return of my BC to lung and bones. Ibrance did not work for me and I got worse on it. However I am doing well with Afinitor, exemestane and Faslodex injections as well as Xgeva for the bone Mets. However the tumor marker continues to rise🤔All we can do is press on, take our pills, get our scans and LIVE our life.
Curious that yours came down so much and hope they will find the best approach.
