Hi there, I'm 8 months post partum and a new mum to a lovely little girl. I'm breastfeeding and four weeks ago discovered a painful lump under my breast. I initially thought it was a recurrence of mastitis but the GP didn't think it was and put me on the 2 week pathway. It took a while for the appointment to come in and so I went to have a scan privately where the consultant thought it was due to lactation changes and thought it was filled with fluid but that I should go to my NHS appointment for a biopsy to confirm.

So I haven't been worrying about it too much since this, but I had the appointment yesterday and the consultant radiologist and breast surgeon I saw disagree with the private consultant and said the lump seems to have a knobbly edge and they also located a lymph node they were also concerned about. They did a biopsy of both the lump and lymph node and told me they have given the lump a grade 3 - indeterminate.

I've been feeling really overwhelmed by this after thinking it was just due to lactation. I'm trying to hold things together but with such a young baby I just feel so heartbroken. I keep looking at her and thinking awful things, like what if I miss her life? She won't remember me. I know it's probably a very small possibility of that happening but just the thought of it is hard to bare. I wanted to ask for your advice on how to cope with the waiting, they said it would be 2 weeks. I've read that there is a low percentage of grades increasing after biopsy but I've also read that breast cancer can be more aggressive in women under 40 (I'm 35) and I could really do with some clear understanding of the stats. 

Thank you for your help
