Stage 4. Sounds like your mom has metastatic lung cancer, even if this is the" slow kind", her life expectancy is probably in the range of 6 months or so. Some patients live a lot longer and some a lot less. Sorry and good luck, make sure that she is comfortable for the rest of her struggle.
Your question has. Conflicting info. Lung ca, 'slow kind', is broncheoalveolar, a non-invasive surface spreading tumor. If it invades, it's not slow; if it goes to bones, for sure it's not slow. Prognosis requires clarification of provided info, multifocal bone scan + carries a poor prognosis.
