Lung cancer spread no treatment

Hello

My dad 82 was fit and well till 4 weeks ago, he woke up and was unsteady on his feet called gp who saod didnt think its a stroke and to see how it goes. 

Same thing happened 2 weeks later so gp sent to a and e. 

Kept in 2 days comfirmed with stroke. And looked like another older one as well on scan. 

Had chest xray while in which saw a legion. 

Booked in for scans following week and sent home. 

On the saturday he slipped off the side of the bed couldnt fell his arm or leg. Ambulance came and took him in. Drs said a seizure from the stroke.

Mum called on monday to ask how he was after stroke who ever answered phone said not a stroke its a brain tumor. 

She asked for dr to call who then said lung cancer spread to brain and liver and 2 months to live. 

This is all from a scan. Cancelled mri and put him on steroids and anti seizure drugs. 

Not been offered any treatment or even a biopsy. 

His actually on stroke ward. 

Apart from the numbness in his arm and leg he hasnt had a single sympton no cough no headaches litrally nothing. Cooks shops walks dog everyday. And such a keen gardener which looks like chelsea flower show. 

Any ideas?
