My husband has liver mets from stage 4 bowel cancer. He was meant to have surgery but in 5 weeks the tumours grew back bigger than before the chemo. He has now been told he will go back on 3 months of chemo and maybe have to stay on it . The tumours are very responsive to chemo but as soon as it stops they start up again. I am terrified. How long can he live on chemo even with breaks. We have a young teenager.
