Sophie, you are here with the most difficult decision to make. Others with higher stage or node involvement really had no choice (which is easier only because the decision is obvious). With your small tumor size and perhaps early treatment, you do have a decision to make.

A couple of thoughts for you:
First, remember every person (or cancer) is unique. There is no way for you or any doctor to know if you are already cured or not.

Second, this cancer commonly re-appears. The traditional term is recurrence but the truth is, it means that it was not cured the first time. In other words it was still there even after the first surgery. If it shows up again it is more difficult to stop a second time and at a cellular level more chances for it to have spread in the interim.

Third, you are young and have much left in life to contribute to the world. For this reason, you need the absolute best professional opinion/s to guide you in your next step. It is not easy and your choices kind of suck. Get yourself to the best advice you can afford.

Fourth, If you decide to wait and see, I would go to two different ENT's from different facilities every month. This may seem wacky but it is your life it is just their job. You can't afford to have less than perfect screening examinations. Your insurance may not approve of this so you might have to make arrangements to pay out of pocket for this. Once again, it is your life it is just their job (insurance or doctor). Do not miss a visit, do not stop at two years. In my opinion, you should continue monthly visits until you outlive the ENT.

Please understand I am not trying to make you more fearful. You are up against an enemy that CAN be beat! However, you must remain ever vigilant.

Take care
