I will see if i can get a copy of the results so I can say exactly what it is - im not sure what a biopsy costs - we don't have great insurance because I am self employed, so Im not sure if it will be covered for us. I would check with the doctor to see if they can give you an idea. Its a pretty simple procedure - he had some peels right on his lips and she just took part of that - I dont think she even went into the lips - so I would hope it is not too expensvie - but everything medical seems to be a lot of money without insurance
