Hi Everyone

My dad 79 years old has been diagnosed with lung cancer he also has COPD. Our family is distraught and don't know what to do or where to turn for help. My dad had lost a lot of weight and due to having pneumonia a few times the scans have shown cancer on both lungs. He is unable to get any treatment due to weak heart and other underlying problems. My mum does not really know what to ask but GP and Consultant have said he can't get treatment and they will just have to treat issues as they arise. Over the past few months dad has no memory and gets very confused and also complains of back pain and gets very short of breath when doing even the easiest of tasks. I just feel so helpless, surely there must be someone we could talk to and even prepare as things get worse. I'm presuming it's stage 4 as both lungs are effected but consultant didn't specify what stage he was at or life expectancy. Please help as we are at our wits end 

Thanks for your time
