Hi everybody. Hoping you all can help me. Unfortunately I found out last week that my dad has got cancer in his lungs and liver. He is 65 years old and already had emphysema prior to his cancer diagnosis. He smoked cigarettes most of his life but switched to vaping a few years ago. 

Currently he is in a lot of pain as his liver is very swollen. He's been prescribed morphine, dexamethasone, and dihydrocodeine. Those seem to be helping but only temporarily.

He was supposed to have his first appointment with a lung cancer specialist today but was in too much pain to attend hospital and we have rescheduled for later this week.

I am here because I am feeling very overwhelmed with all of this and would be very grateful for any advice any of you can share with me. I am especially keen to hear from people who have gone through a similar experience with a loved one. What treatment helped? How did you get through it? 

Thank you.
