My father in law is 79, was admitted to hospital with a collapsed lung and fluid on his lung. He was then diagnosed with lung cancer which has spread up to his shoulder and into his neck. He was told to enjoy time with family and has approx 1-2 months. He is being released from hospital and my mother in law keeps telling us he is fine and will get better and we are never there when the doctors come round. Is 1-2 months a likely timeline?
