In classic surgery the dermatologist removes the skin tumor which is visible and also removes a big part of healthy tissue in order to maximize the possibility of total tumor removal.

Then it is sent to the lab for tissue processing, which takes time and the results are available after 15 days. Conversely in Mohs surgery the skin cancer is removed with the least possible removal of healthy tissue.

Then on the same day and moment after the removal a procedure takes place and through microscopic examination the answer whether it is completely removed or not is given immediately and not many days afterwards.
