Hi Clare
I am so sorry you are having to join us but you will find so much love, encouragement and support on these forums.
I am replying to your thread because I feel my own situation and diagnosis has a lot of similarity.
In February this year, I had a WLE and a SNB for a grade 2, small tumour with some DCIS spread. My nodes and margins were clear so I thought rads (always done after WLE) would see me done and dusted.
However, I too am HER2+ and regardless of how early the initial tumour was caught, being HER2+ significantly increases my risk of recurrence.
In the UK, Herceptin (the treatment for HER2+) is always given after chemo for primary adjuvant treatment. I was mortified. But then my onc explained that although it was very unlikely any cancer cells had left the primary area, cells can also spread through the blood, not just the lymph, and all it takes is one tiny micro-cell to start it all off again.
He told me the chemo was belts and braces - just in case there is an odd cell lurking - and the herceptin would change the environment so the cells don't mutate again and become cancerous.
I couldn't have lived with the uncertainty of wondering if I had done everything I could. Herceptin treatment is very expensive, they wouldn't give it to us if they didn't think there was a significant benefit.
Chemo is crap - lets be honest here. But last week saw me finish my last chemo and I am glad i did it, the journey was never a solitary one and i have made some wonderful friends through this forum.
The decision you make Clare has to be the one that is right for you and the one you can live with long term. My love and thoughts are with you.
