Thank you for using Ask a Doctor Service from DoctorSpring. I can understand your problem, and will try to help you the best possible
Firstly, I want to reassure you that papilloma is not a cancer, it is a simple benign lesion.
I have seen the pictures and I can see some changes in color of lesion on left tonsil. I think biopsy will be a safe option.
Hope this helps. Feel free to ask if you have any further queries.
