I have a mass on my tonsil too big to remove how will they shrink it if not cancerious? I can't breath hardly laying down and my mouth will not open wide it has to be removed!

There. There are definitely ways and techniques to perform this. I am hoping you are under the care of an ENT physician or a surgical oncologist. It is stressful to have a situation like this, but I assure you this can be taken care of. There is cautery, surgical resection, and other methods to solve your problem. Please be sure you have seen a specialist and have this taken care of.
