Surgery

My seven year old girl is having surgery tomorrow. She has a "tumor" that seems more like a nodule to the side of one knee. It's not malignant and the surgery is ambulatory, barring the unknown, but my wife is worried. I am too, but after nine years of one thing after another I'm kinda numb. I've pushed worry back behind a wall until the surgery is complete. Afterwards I'll let it go. I'm 99.9% sure my baby will be fine. Really. I am.
