My Dad was diagnosed with Non Small Cell Lung Cancer on 1st April 2018. He is 66 years old and has smoked for 55 years. His 68 year old sister died 18 months ago of Breast Cancer and his Mum died at the age of 71 of Bowel Cancer. I am heartbroken and would like some advice on whether he should have Adjuvant Chemotherapy as he had a successful Open Surgery Operation to remove the 2 lower lobes in his right lung on 5th May 2018. Technically he is cancer free now so are the risks of Chemotherapy worth it?
