good scan and not so good scan

My MRI of the brain came back good, yeah! But my ct scan of my lungs shows a new met. I have been on a break from chemo for the summer so I have had a great summer and time to rebuild my strength to fight again. Friday I go on navelbine and herceptin. I have taken navelbine before and it didn't work. When I mentioned this to my Dr. he said he hoped it has been long enough ago that it will work this time. He is working on containment and quality of life so he wants to start me out on the chemo's with the least side effects. So I will once again begin my fight. Patty H
