You've got to love a surgeon that calls you out of hours. She's in agreement that a biopsy is needed. Still the chance that it's something other than cancer but it could be cancer so best to be sure....
The sooner you have the biopsy,the sooner you will know.Waiting for 3 weeks would not be good,so your decision to have it done locally is really sensible.Thinking of you:) xxxRobyn
