My 72 year old husband was diagnosed with lung cancer after an MRI scan for his heart. It had been caught early and he had keyhole robotic surgery in June. 10 lymph nodes were removed and cancer was found in one. He will be starting his chemotherapy in approx 2 weeks. The chemotherapy is a precaution and he will be having 4 sessions 3 weeks apart. He is worried as his immune system is very low already and seems to get lots of infections.
