Hi, my father was diagnosed with advanced small cell lung cancer on 13th November this year, and we were told he has weeks to months at best. 

He has already lost a great deal of weight, has an awful cough and whistle, and his throat is very painful. When diagnosed we were told it was in the lymph nodes up his throat. 

Already, he cannot sleep due to the coughing and spluttering (it doesn't sound like a real cough as it's weak but full if that makes sense). Now he feels like there is something stuck in his throat and he is struggling to swallow

He is very stubborn and hates doctors. Does this sound like it has already gone into his throat? Does anyone know if there is anything that can make it less troublesome for him?
