Fingers crossed its localized or local- regional is as far as it has gone. (lymph nodes) I know it's terrifying - truly - and after a recurrence hope is a bit shy in coming, but you are very lucky on certain things. 1 - you aren't at the point where you've had treatment and are facing a recurrence, because all options are still open to you. 2) this seems to be caught early, so likely no further involvement. 3) you're young and healthy -something that not every cancer patient has going for them, and finally if this is a second primary - and
HPV related - as you've likely heard dozens of times.... It responds very well to chemo and rads.
You will get through this... Hugs and blessings to you!
