Hello Moulton Lady, and welcome to the Breast Cancer Care discussion forums, where I am sure you will get lots of good, honest support from the many informed users of this site.
You say you are having your surgery tomorrow and are somewhat apprehensive, please do give the helpline here a ring and have a chat with the staff, they're here to support you through this. Lines are open now and until 5pm tonight. Calls are free, 0808 800 6000.
Welcome to the Breast Cancer Care Discussion Forums. I'm sure other forum users will be along soon to offer support but in the meantime I thought it might be helpful to post a link to the BCC publication 'Treating breast cancer':
Please do also give the BCC Helpline a call if you need to speak to someone in confidence, they can offer information and support tel. 0808 800 6000. The Helpline reopens tomorrow morning at 9am.
With best wishes,
Anna, BCC Facilitator
