Preparation:
 Tell your doctor about chronic diseases, drug treatments, and known allergies (especially to anesthetics or antibiotics). Tell your doctor if you are taking anticoagulants or antiplatelet drugs (aspirin, warfarin, clopidogrel); it may be necessary to adjust them according to the specialist's recommendation. Avoid drinking alcohol 24 hours before. Make sure the skin around the formation is clean and free of active infection.
