Tonsillitis. Swallowing , is it cancer?

I had covid on 28 april had sore throat , since then one side of my tonsil is swollen , i had a very bad health anxiety , i google searched the symptom and as usual google clearly said throat cancer , idk what should i do, only one sid of tonsil is swollen , although there was no pain till now but since last 2 day i was having a little pain , which is improved today , btw had my all body profile test done after a month of covid everything ca normal except high cholesterol , i had difficulty swallowing , is it cancer? , My cbc was normal though at that time except one or 2 thing which i dont remember but it was something like distribution of rbc idk , should i have more tests done , can it be cancern , i dont have any difficulty or anything in throat whatsoever , but as i said since last 2 days a little sore throat.
