It sounds like you have had a great team with a good surgical plan and that you have come through this surgery well. No mean feat on your part.
Next comes the chemo and radiation. This is not an easy treatment, but very necessary to achieve that cure I know you want.
I hope you have family and friends to support you through this next phase of treatment.
Take care,
Tammy
