can anyone tell me please. if you are diagnosed with metatastic breast cancer in the liver with one isolated tumour 2.5cm ,and you start off with chemo and it shrinks it to 1cm within 6 months ,then you have a masectomy.after the breast surgery you have radiation then start off with chemo,but the chemo has no effect so the same tumor grows back ,for how long would you carry on with chemo ? what other treatments would benefit as its only the one solidary tumor in the liver .i was thinking of resection
