How long Should I continue herceptin ?

[Raquel]

I haven't posted in a while, it's been two years I'm NED and onc. Is talking about stopping herceptin. I have been on herceptin on and off for about five+ years. Anyone else a long term herceptin user? The one time I did stop my cancer came back within 3 months, so I'm a little afraid to discontinue it. My heart is good and I have no noticeable side effects. Any advice or experiences would be greatly appreciated! I'm currently stage 4 NED had a lung met in 2011 removed with surgery and taking tamoxifen. Really want to remain NED!
