Can anyone tell me what side effects they have experienced with Herceptin injections please?
Hello sueque1
I am so sorry to hear about the bad side effects of the Herceptin. I had to say I was dreading it.
I have been ever so lucky though, I asked my oncologist for an HER2 retest because I was borderline with the ICH and then marginal with the FISH test and it came back negative. Because I was then ER positive and HER2 negative I was able to go for the Oncotype DX test which also confirmed I was HER2 negative and also that my cancer recurrence was low so now I don't need Herceptin and I don't need chemo either.
I am however facing a second surgery because they discovered occult DCIS which didn't show up on the mammogram and so now I am going for further surgery with hopefully partial breast reconstruction. No doubt this will be followed by radiotherapy
I hope it improves for you

Hello Margaret
I was initially diagnosed ER positive and then HER2 Positive. They told me that if I was HER2 positive I would need Herceptin and Chemo. I was told Herceptin would not work without chemo? Why were you prescribed Herceptin without chemo?
Best wishes

Hi
Sorry wasn't clear enough ..I meant SE were easier than the ones I had on chemo . My story on my profile .
Story started last June with mammogram then diagnosis
followed 8 days later by MX then chemo now Herceptin and Bisphosphonate.
its correct that in this country N.I.C.E. states you don't get Herceptin without chemo .
Sorry bout mix up keep well
