Hi, Michelle
With 6 cm and no other visible activities, you and your doctor may easily decide to do it in January. There are several surgical options, some may reduce your recovery time. Suggest you read Cancer Guide - website by Steve Dunn. A lot of useful and detailed info.
Just remember - your caught it at 6 cm without any visible activities elsewhere. That means it's localized! It might be a surgery is all you'll need.
You have a lot to worry about - bringing up your kids and then to manage a babysitting for bunch of future grandkids.
