Hi Yassi
I too had a large tumour like you and mine was estrogen positive too. And also like you I got my pathology results around Christmas time. Mine was in 2007 when I was 36.
There is lots on your mind at this time I am sure and chemo is such a scary prospect from the outside, but it is definately doable and so many women on here to testify that it is a little rough, but you will come out the other side, dust yourself off and get back to where you were before you heard those chilling words "you have cancer".
Take care and have a Merry Christmas. My wish for the New year is a cure for cancer.
Love Tanya xx
