I was diagnosed with DCIS after routine mammogram 9mm. Consultant brilliant, such a positive lady, who always gives you a hug! She performed a lumpectomy and I went for results today. Margins were clear one side, but up to the edge on the other, so she wants to take a little more. She also said there was 4mm of cells that tested invasive in the centre and she has removed those. She has put me on Arimidex for 5 years already as she saw I was in such a state. She said my tests showed I was ER positive so this would protect my breasts for 10 years. She also said I was herceptin negative, which I don't really understand, but she said this was good. She also said this wouldn't shorten my life, which was comforting, but I must admit I am very tearful and highly anxious at the moment, normal I guess! Good luck to all you brave ladies xx
