Hi @cakey2000 and welcome to the community, though sorry to hear about your nan.
Can I ask was your nan just diagnosed? Were any treatment options discussed?
It might help to look at our pages on Lung Cancer that might give more information about what a diagnosis means, treatment options that might be available and what might happen next.
How is your nan now? Many of us on here have learnt to live day-to-day as a way of coping recognising that some days may be harder than others but good days can be very rewarding.
<<hugs>>
