Survival rate

First time posting. 
Diagnosed with HER2 positive breast cancer last year. Had mastectomy, chemo and radiotherapy. Still having Herceptin, pertuzamab and bisphosphenates. 
At my last consultant appointment I asked about my survival rate prognosis as medics had previously asked if I wanted to know the statistics. I was told my 10 year survival rate was 41%. Since finding out this information I have become a little preoccupied. 
Anyone else in a similar position with any words of wisdom please?
