My dad got diagnosed with stage 4 lung cancer 8 weeks ago after we found secondary brain tumours on his brain. He had a 7 day course of radiotherapy to relieve swelling on his brain to hopefully give him a while longer. 5 days into the radiotherapy we had to stop treatment as he couldn't see and symptoms got so bad. 3 weeks on now and I found my dad in bed unable to move his legs, he can't walk at all now and had urine infection I'm caring for him at his home. But today he had a fall, fell unconscious and I found him on the floor.. he won't leave home he's very distressed and agitated. He's coughing up mucus, won't eat or drink, can't urinate. Keeps falling to sleep alot but waking not long after . He begged me today to let his suffering stop.. he wants to die. He's on oral morphine and steriods for swelling on his brain. Am I to expect worse or is his suffering nearly over. He's asked me if we can stop his steroids hoping he'll go sooner but I don't want to cause anymore pain. I Need advice please if anyone can help.
