Sickness - Will surgery be rescheduled?

It is two days until surgery, I hope.  I have a cold.  Today is the first day my left lymph node is no longer tender to the touch.  The right node never got tender.  I am hoping for a miraculous recovery, but I know I will have to call the surgeon's office tomorrow morning and let them know I've been sick.  I fear they will reschedule the surgery.
