Thanks so much for your replies, reassuring to speak to people going through the same thing.
My lump does feel bigger after since I had the core biopsy (nearly 2 weeks ago) and it's still bruised. The nurse told me it would be like that, so I haven't worried about it. I asked my surgeon the same question about it growing - he said a couple of weeks makes no difference.
It sounds as though you could benefit from calling our freephone helpline 0808 800 6000. It is open 9-5 Monday to Friday and 10-2 Saturday. They are breast cancer specialists and will be able to help you with your questions.
I am sure it will not be long before you have other forum users replying and offerning support.
Hi, I am newly diagnosed with grade 3 triple negative BC. I have BRCA1 gene and was due for preventative mastectomy on 7 November, so this was all a bit of a shock!
My query is, I had a core biopsy 2 weeks ago, I still feel very sore and the lump feels like it has grown. Can you tell me if you think I could still be swollen after two weeks, or whether the cancer could have grown within this time?
