Hi I am hoping someone can help. 

Dad has stage 4 nsclc he was dx in feb 2012 stage 3b in feb 2015 brain mets were discovered. He received wbr but we don't know if successful as no scan yet. Dad began docetaxel for the lung cancer on Wednesday, he was deemed fit enough tho how I don't know- he has lost 2st in weight, has trouble eating drinking, gets a lot of nausea,pain s above left eye, tired the list goes on this has all been happening even before wbr it's what led to getting a brain scan. Since the first infusion dad has felt worse swollen ankles, shaky hands, red torso and just feel weak. The oncologist at time of talking about treatment gave 3 options do nothing, chemo or tablet-biological. I am wondering if after 1 infusion of docetaxel dad can change to the tablet and stop chemo? This is 3rd line chemo so no hope of changing chemo. 

Also is it possible to get a second opinion from a different oncologist on from the same hospital? 

Dad also has angina and a collapsed lung and fluid that hasn't been treated.
