^*The surgical margins can be modified to contemplate anatomical, functional or aesthetic needs. Experts agree that margins between 1cm and 2 cm are acceptable in areas where margins of 2 cm would cause significant aesthetic, functional or anatomical losses. The patient should be informed and agree with the doctor about the best option.
