My mum in law was diagnosed with stage 4 lung cancer in August. In October she had chemo but after 1st session ended up in hospital for 2 weeks with an infection. Oncologist said she was to weak for chemo but she did have 5 sessions of palliative radiotherapy which has really helped with her breathing although she is still very tired. She visited her oncologist 14 December and he was happy with the radiotherapy and booked to see her end of February. This seems a long time without treatment I know they talk about quality of life are they anticipating she will never have anymore chemo? She was referred for chemo the day after diagnosis but now it seems quite relaxed and no rush for her to have further treatment.
