Does anyone know whether a woman who is diagnosed as her2 now with BC mets would have to have been her2 for the original BC and any other mets in the past? When I was first diagnosed with BC in 1985 there were no tests given for the her2 gene. The same is true for my first mets in two vertebra in 1990. Now over 20 years after my first DX and first mets I have tested her2+++ with lung mets. I am trying to understand if I've always been her2, just not tested, or if I have become her2 now for my latest mets many years after the first BC and mets. After a year on herceptin and femara (and navelbine the first 6 months) a recent PET scan shows no evidence of cancer. Does anyone know where do I fit in with the questions and answers on this topic? Just curious! Hugs, Tricia
