My father in law has been on 4 cycles of Erbitux and 16/30 IMRT sessions. In the last few days the ulcers on his lips have become large and white in color and his lips are swollen. The medical oncologist said that this is mucositis and that because of this he is stopping the Erbitux for now. I am concerned that stopping will have even more harm than the mucostitis and wanted to know if anyone shares a similar experience or knowledge of this issue?

I have much more to share but will do so in another post about what I have learned about oral tongue cancer.
