Our daughters grandad has been given a few months to live. He had a seizure a few weeks back then we found out he has lung cancer that has spread to the brain and elsewhere. He has had 1 week worth of radiotherapy and will be starting chemotherapy this week. He's already lost his hair. Our daughter knows the truth her grandad is very poorly and will be going to heaven soon. Our daughter is grown up for her age and understands. I'm very worried that the chemo will make him detoriate fast does it? Any advice on how we can explain this
