HER2 positive and metastatic as the biopsy of right lung showed inflammation which they took very seriously :) left breast masectomy and lymph node clearance Dec. 2011. I had my first Herceptin infusion on 18th July, 2011 and continue to have infusions every three weeks. This Sat. is no. 103. I have three monthly heart scans and so far so good. I took Arimidex for about six years and then changed to Exemestane. I've had three local recurrences which meant two surgeries and last Aug. 15 radiation 'zaps'. Good to know that others are doing well with long term treatment. Thanks Mazzi for starting this discussion! xBeryl
