Hi there --
I second what Pickle said regarding consulting with a gyn/onc.
The wording from your report is a little unclear, and was noting that basically you didn't have a very big margin from that surgery. However, since you've had a hysterectomy, the findings from that report are really not so relevant since you've had the entire problematic area removed. Metastasis to the lymph nodes with microinvasive cancer is very uncommon, and it's my understanding that often with Stage Ia1 they don't even check the lymph nodes since there is virtually no chance of them being infected. I was Stage Ia2/Ib1 and they checked my sentinel nodes (3) and took the obturator nodes (8 of them, and they were located near the ovaries), and thankfully all of mine were totally clean and disease free.
If you had squamous carcinoma, that is usually caused by hpv16. Without the cervical tissue to attack, there is a chance that persistent hpv infection could then attack the vaginal or vulvar tissue, but this is rather rare. Having the hyst was a smart move, and will in all likelihood end your battle with hpv. The recurrence rates for someone at your stage is approximately 4-5%.
One thing that is super important is that you faithfully keep ALL of your follow up appointments so you can be monitored to make sure nothing new pops back up. If you find yourself without insurance, there are programs that can help defray the costs. I believe the American Cancer Society has a program for cervical cancer screening and care, and there may be some others.
Good luck, and keep us posted how you are doing! Having been caught early, cervical cancer is very "curable," and your surgery should be all the actual treatment (aside from monitoring) that you will ever need
