I am a 21-year-old male. Around 8 days ago, I noticed two white patches on both tonsillar pillars at the back of my throat. They appeared before I developed a sore throat, fever, and body aches. My GP diagnosed secondary bacterial infection with stomatitis and prescribed antibiotics. My sore throat, fever, and body aches have resolved, but the white patches remain. They are not painful, cannot be scraped off, and feel only slightly raised without a hard lump underneath. A dentist suggested acute tonsillitis with ulceration. I vape but do not chew tobacco. Does this look more consistent with healing ulceration/infection or something like leukoplakia? Also i have attached image for reference I am actually worried about it being mouth cancer as i searched it online.
