I have gone through the break out stage, and then the ends of my fingers began to split. It has been 4 months and I feel fine. However, a couple of weeks ago, my hair began to break off and fall out. It is now very thin, normally I have extremely thick hair. I have been on 150mg and last week the doctor said I could now go down to 100mg to see if the hair shedding would stop. I will not have a CT Scan until June 2nd, I will let everyone know how it goes. I have stage IV Lung Cancer and have been beating the odds for 4 years. My radiation doctor says the latest spot could be radiated, so if the Tarceva does not get rid of it or shrink it dramatically. I will have more radiation. I originally had 6 months of chemo and then 37 radiation treatments, it was gone for about a year, then 6 more months of chemo and it was gone again. Good Luck to All
