1st I want to reassure you that papilloma is not a cancer, it is a simple benign lesion. Sometimes it doesn't require any treatment, but if it is increasing in size we can remove it.
I have seen picture and I can’t see any papilloma or any other lesion, actually picture quality is very good but left tonsil area is not fully covered so I can’t see any lesion in that area. I have labeled the picture (you can see it). All structures seen in this picture are normal.

Finally most of the time feeling of lump in throat is due to acid reflux. It can be treated easily with life style changes and you can start tablet. Rabeprazole 20 mg once in morning before breakfast for one month.
Hope this helps. Please feel free to ask if you have any further queries.
