Hello Marie and thanks for posting, 

I am sorry to learn that you have to go back to the clinic next week for a biopsy. This is usually a stressful situation and unfortunately, one where no one here on Cancerchat can give you any clarity. If the doctors want a biopsy then I'm afraid you will need to wait for the results, although when you see the doctor next week they may be able to tell you more. Try not to assume what this lump is, as everyone imagines a worse case scenario and breast lumps can occur for other reasons besides cancer.

For now I think you are in the thick of it, which is inevitably a worrying situation. My advice would be to stay off the internet as searching for answers won't tell you if there is anything wrong and keeps the worry front of mind. Try and work out ways to manage the worry for example by distracting yourself and staying busy. 

Give us a call if you want to talk anything over please. Our number to call is Freephone 0808 800 4040 and the lines are open from 9-5,  Monday to Friday.

Take care, 

Julia
