Hi Karel
You are experiencing what most if not all of us fear - being told we have Metastasic return. I, myself have not had this only just finishing treatment last December. However having been Stage 3 Grade 3 with megametastisis to 4 lymph nodes it is everpresent in my mind. Through all of my research I do not know what way I will go if it ever happens but I know there are heaps of positive stories out there. Just an option, have a look at Radical Remission by Kelly Turner. She has a book and there is a web site etc... I am Not making any recommendations at all, I guess just sharing something that, if I am faced with what you are facing, It is something I will definitely consider along with or instead of the traditional method.....
Sending love and hugs xx
