My dad was diagnosed with lung cancer this January, it had already started to spread to the bone and was at a late stage, however he had chemo and although it was awful it did shrink the tumour and gave him extra time I think! Just the chemo has taken its toll on him, his last check up was in August and the tumour hadn't grown but he's started to have pain in his hips and funny sensation down his legs and more concerning he feels sick all the time and not eating, the Drs have given him more painkillers and different nausea tablets but nothing working. Does this sound like it's the cancer? I'm wondering how long he's got ?
