I was in a similar situation back in 2015 but it was a mole. I went to the dermo about others I was concerned about but they picked up on a huge one on my back that had been there since I was young. They told me it was a precaution and it was the worst 3 weeks having to wait but it came back fine. I know it’s easier said than done but please give google a wide birth, it will only make you feel worse and it isn’t reliable. I’m sure you will be fine given the length of time you’ve had it for.
