In healthy individuals, the use of Mohs micrographic surgery for low-risk, small (< 1cm), superficial or non-aggressive (based on appearance under a microscope) squamous cell carcinomas and basal cell carcinomas is inappropriate for skin cancers on the trunk and extremities. In these areas of the body, the clinical benefits of this specialized surgical procedure do not exceed the potential risks. It is important to note that Mohs micrographic surgery may be considered for skin cancers that appear on the hands, feet, ankles, shins, nipples, or genitals because they have been shown to have a higher risk for recurrence or require additional surgical considerations.
