My dad has stage 4 prostate cancer with bone mets 2.5 years since diagnosis, diagnosed with colon cancer last September. Hes currently having zoladex injections every 12 weeks, and enzalutamide since Feb. Hes really going downhill in the last few weeks, he's on a low residue diet with the colon cancer, but he's struggling to eat anything. He does have fortisip and complan daily but I wonder if there's anything else I should be doing? I had the doctor out to him on 9th July, but blood tests came back ok. I am so scared I am missing something
