Waiting biopsy results....

Hi, I'm 33 with a strong family history of breast cancer.. both grandmother's before 50, mother diagnosed 3 times at ages, 35, 42 and eventually died shortly after her 3rd diagnosis at 47. Auntie on my dad's side had a preventative double mastectomy as she has the faulty gene that I can't remember the name of. I was given an urgent referral to the breast clinic after a phone consultation with the gp, based on family history. The surgeon felt a lump and sent me for an ultrasound, the radiographer then performed 2 core biopsies (burst into tears when he told me they had to do it!) The letter that followed the appointment said a 2cmx2cm tri-lobular mass with some calcification.  I'm now almost two weeks into the wait and believe it's being discussed in the multi disciplinary meeting tomorrow so I guess I'll hear in the next few days.. I'm worried to death as I've lost 40lb since the end of March due to lack of appetite, I literally have to force food down and I'm normally a big eater! I'd not questioned the lack of appetite but now I'm kicking myself as maybe I should have questioned that sooner.. I'm not sure what I'm hoping to gain from posting here but if it's good news I'll be back to update to hopefully help reassure future 2 week waiters and if it's bad news I'm hoping to find a bit of a support network!
