Hi Habbas, welcome to this fantastic site of supportive people.
You are so fortunate to have had your cancer diagnosed as a Stage 1. Surgery would be the preferable option I would think, though if necessary this could be followed up with radiation. As your cancer has not spread anywhere you would be unlikely to be offered chemotherapy.
Perhaps you could seek a 2nd opinion if you are not satisfied with your current surgeons opinion of going with surgical excision.
I wish you all the best and do let us know how you get on. Take care,
Tammy
