I have never had surgery with general anesthesia before and I am so scared I will die during it.

I hate the thought of being put under so badly that I want to just skip the surgery all together. But, I don't want to keep having to worry that this freaking cyst is sarcoma when I know that it's benign. I hate health anxiety. But, I don't know what to do anymore. I have no clue why they just can't give me a local and then just take this out. I'm thinking about looking for a second opinion to see if we can do a needle biopsy. What should I do?
