Can someone tell me what this means?

My gyno told me I have stage 1 of a pre-cancerous condition. I think stage 5 or something is cancer. He said they can remove it in a simple surgery but I had a lot to do so I asked him if it can wait...3 weeks of bleeding sounds like loads of fun but I have a lot of dress and skirt events coming up. Plus, I dont mean to be "that guy" but didn't they used to just knock you out for these procedures? When did that change? 
Anyway, I have had cervical cancer before which was removed. He assured me this is NOT cancer, just a pre-cancerous bundle of cells and he wouldn't answer any other questions like? 
Will it become cancer? He doesn't know. 
Can it go away on its own? He doesn't know. 
Then he says.  I did my due diligence and informed you, let me know what you decide...
Has anyone had this? What did you decide? Is this some Indiana Jones holy grail question where if I make the wrong choice the cancer is back? Cuz that operation sucks I think more than a 5 minute procedure. 
But I also can't shake this feeling that they're constantly cutting chunks out of my womanhood and soon there will be nothing left...dumb I know. 
I'm hoping you guys will be more helpful than the gyno because I have no idea what to do after talking to him.
