My father had his second occurrence with cancer two years ago. He had lung cancer and had 30% of his left lung taken out. After that, he had chemotherapy and millions of scans done afterwards. He currently has non-small cell cancer spots in his abdomen and his doctor prescribed Tarceva for him. He has been on it for about two weeks now and has a horrible rash/acne on his face and throughout his scalp that is terribly painful. I understand this is a side effect, but was wondering if anyone had had previous experience with this drug enough to tell me if the rash/acne ever goes away? I have also heard that the worse the rash, the better the drug is working. Has anyone had experience with this as well? I am not sure because he has yet to go to his scan because it is not until December. I am extremely worried about him. If anyone has any previous experience, please let me know. Thank You. God Bless.
