Mohs micrographic surgery is a surgical technique used to very precisely treat skin tumours, allowing us to avoid removing more than necessary (reduces the risk of scarring) or less than necessary (reduces the risk of recurrences).

This surgery is recommended when the tumour has been treated previously and has recurred, as well as in areas where it is in the patient's interest to preserve the tissue as far as possible for functional or aesthetic reasons (nose, eyelids, eyes), in young people, and in tumours with poorly defined edges.

The tumour is removed and analysed under a microscope immediately to check that removal has been carried out fully. If it has not, the tumour will continue to be removed from the affected area until completely eradicated.


Days before: In some cases, your dermatologist may recommend you take an oral antibiotic before surgery. Do not take any anti-inflammatory medication or consume alcoholic drinks. If you are taking anticoagulant medicine, consult your doctor as in some cases it must be stopped or changed before surgery.

The day of surgery: Have breakfast and take your usual medication. We recommend somebody accompanies you. The process may take 2-6 hours. In the majority of cases, you may return home after surgery. We recommend 24 hours of rest and the use of analgesics for the pain.
