Brief Answer:
Nabothian cyst, electrocautery/ cryofreezing
Detailed Answer:
Thank you for asking!
Its good news that all the labs including pap smear are ok and its slight cervical cyst which the gynecologist has decided to remove in office. Means she will do it as out going procedure with local anesthesia and then after some time your wife can go home. Most likely cause of this cyst is blockage of mucus producing nabothian glands which leads to cyst.
The procedure would be fine and innocuous. Just Drainage of the cyst under aseptic local anesthesia and she would be good as new. Her doctor will use either electrocautery and cauterize it or will use cryofreezing. Thats it. Perfectly safe and easily doable procedure. so chill up.
I hope it helps. Take good care of yourself and dont forget to close the discussion please.
May the odds be ever in your favour.
