long term herceptin for bc mets....

Found an old discussion from Kari_2015.  Just wanted to let ladies know that I have been on Herceptin for 13yrs. Managing to keep lesions only in bone so pretty happy with that... Only know one other lady that is on herceptin still...been 11-12yrs for her too.  My understanding is that if you are going to have problems cardiac wise it is more likely to happen in the early stages. I have reg echo's done.  Get pissed off with having treatment at times but very thankful for this drug... would love to hear from others that are on herceptin long term.. cheers :)
