Possible squamous cell carcinoma on my arm

So just got back from Gp and referred to dermatology. Possible SCC on my lower left arm. Bit in shock. He’s not sure if it could be basal cell as I have been picking at it for months so may have damaged it. I’m so anxious right now. It’s small but what does that matter not had it long but I am concerned reading about the survival rates. Anyway feeling a bit sick so any support gratefully received.
