Hello. New here. Never expected to be here!

I have a question. Firstly I hope you are all in your best health. The question is, and this is going to be longwinded, apologies. 5 years ago a lesion was found under my tongue, dentist visit. They sent me to Kings. It was on the vein so they never took a biopsy, just monitored it and took photographs. The lesion is white. They discharged me after a year. 4 years later I get tooth ache again. Very poor dental hygiene on my part. The lesion is there has grown slightly, so I go to Northwick Park hospital, go under GA and they whip it out. Job done. You think. So 2 weeks ago, I get toothache….. again. The dentist calls another dentist in. Lesion back. Fast tracked to MacMillan Centre. Biopsy, well they could only get a bit of the front bit, they said they might have to book me in under GA to get the other bit from the back. Had an MRI. And I got a message Friday. They want to see me in 2 weeks. It’s a 15 minute appointment. By the way my consult said it’s red and whiteand 2cm. I was told the one that was whipped out was pre cancerous, and the doc said that is why it might not be good.  I’m not scared. Just a bit pissed off that if it is something nefarious, just pick the phone up and call me. Is this normal???  I don’t know what on earth is happening. My appointment is the 29th
