papillary thyroid cancer?

I’m being checked for thyroid cancer and may need surgery, so the doctor says. Is the surgery scary and how soon will I have the surgery after being diagnosed?? a week or two or within days?
For those who don’t understand the question, how long will i have before i absolutely need to have the surgery done?? Is it immediate or can it wait?? I already had my biopsy done, waiting on results, once i get the results and need surgery, how long till I have the surgery??
