Recently diagnosed

My 76 year old husband has been diagnosed with Stage 4 lung cancer, metastasized to the brain, liver, adrenal glands and lymph nodes. He also has COPD and diabetes...

He has had 5 radiation treatments to the brain and 1 IV chemotherapy so far.

The chemo was harder on him than the radiation treatments. He goes for another chemo in about 10 days, at which time they will do another MRI on his brain.

Doctors say approximately 7 months life expectancy..

Anybody have any idea of what I can expect in the progression of this disease?
