Who found their own 'lump'

Sure I only checked my breast's in October when I got a "How to Check your breasts" information. At the end of November, 2012 checked again and found what I thought must have been my rib in the lower left breast but didnt have a matching one on the other side so off to the Drs, Ultrasound, (previous U/S only done in May, 2012 showed a cyst which was biopsied and fine) and cone biopsy confirming the news. Lumpectomy and 2 Lymph Nodes removed during surgery which tested Neg but at follow up appointment was told 1 Lymph node did have a little bit of cancer in it.I have also tested HER2 positive. I am seeing Oncologist this Wednesday to be told what my treatment will be, which so far have been advised will be chemo, Herceptin and radiation. I'm worried about seeing Oncologist and hope I have a nice positive one. So my journey is just beginning and I'm scared
