One or two optical fibres are inserted via ultrasound guidance into the nodule through extremely fine gauge needles. The treatment session lasts from 10 to 20 minutes, which is the time required for the heat inside the nodule to destroy the treated tissue. No incisions or stitches are required and the entire session, including the preparation time, takes just 30 minutes.
