My 77 year old father was diagnosed with stage 3b lung cancer in Jan '08, He has been on Tarceva for about 3 weeks now, he is experiencing mouth sores as well as dizziness. Has anyone else had similar side effects? He has a collapsed right lung (the one with the tumor) with full function of the other lung, he has recently been taking oxygen on a regular basis. Apparently the cancer has grown but not spread outside of his right lung. Does anyone have any advice or suggestions?
thanks
