This wedge of tissue is sent to the laboratory where many many slides are made and examined to be sure invasive cancer is not missed if it is present. Examination also makes sure that if there is invasive cancer, the depth below the basement membrane is adeqautely assessed. Once the wege of tissue is removed, any bleeding that occurs is either cauterized or a solution is placed that will stop the bleeding.
