my husband was diagnosed approximately 3 wks ago with stage 4 adenosqamous lung carcinoma with metastasis to the brain and liver. he has had ten sessions of radiation therapy to the brain and will begin chemotherapy on jan 6. we haven't had any communication with the radiation oncologist and haven't yet had a consultation with his oncologist. i would like to know the prognosis for this condition, the approximate survival rate and the possible time he has left. my husband is very uncomfortable discussing this. his lung tumor is 5 cm. he is 73 yrs old and has copd, but until this surfaced he was active(working full time, hunting, fishing, gardening, showing dogs, working on our new home, and showing, rallying and racing our classic car. he currently has no energy, sleeps approximately 16 hrs/day, and doesn't even have the energy to walk out to the garden. he is also quite frustated and depressed because of his limitations.
