hi my mum is newly diagnosed with terminal cancer, it's a cancer of unknown primary in her spleen and possibly lungs ? I'm sat here thinking should I be looking for more answers ? Oncologist said not doing investigations as not fair on mum and may not find the Primary .. treatment would make mum too poorly, we are now at home just carrying on as normal as we can. Feel a bit like we have just been sent home and that's it. Got Palliative Team involved but still feel very overwhelmed right now. Should I be probing further for investigations or will this have already been decided at MDT ?
