Hi,

So dad has been through intense chemo and radiotherapy (both to the chest and the brain) since being diagnosed with lung cancer back in September 17. He did ever so well, still continued to work through treatment, ate all round him, gained weight, breathing eased drastically and just looked healthy again. Scan results have since come back and all in all, look pretty promising (As far as cancer goes) and 3 weeks ago - received the final after treatment scan which the professor was more than pleased about. 

However, he has since took a very downhill spiral - exceptionally tired and spends about 20 hours a day in bed. Feeling very weak & grouchy, not eating thus has lost a fair amount of weight, absolutely no energy what so ever, and suffering with back and jaw ache.

We always knew that the radiotherapy could have long term affects (in fact they stipulated 6-8 weeks after treatment he could be worn out) but it doesnt seem like hes getting any better and is in fact getting worse. 

Has anybody else experienced/or know of anyone who has experienced similar after affects? Is it nromal? Will it improve, or is it a bad sign? 

Any feedback/advise would be exceptionally appreciated. 

Thanks so much
