Mouth/throat bumps

I’m new to this forum, but I’m currently in a massive panic because I see weird bumps in my throat. I vaped for 7 months and recently quit, but now I’m paranoid about oral cancer and am driving myself crazy. I saw my regular doctor, who said my mouth looked fine, but to see my dentist if I’m worried. Can someone tell me if anything in the pictures looks like an underlying disease? (The bumps in the back of my throat especially).Thank you.
