Steps to take before the procedure
The surgeon will provide with the exact guidelines on preparation on the lines of what to eat and drink, smoking, taking or avoiding some specific vitamins and medications, and also on washing the face. Certain medications such as blood-thinning medicines should be avoided for at least 7 days prior to the surgery. If the patient smokes regularly, he/she should quit at least 3 weeks before the surgery.
What happens during the surgery?
The procedure is performed while the patient is awake after a cleansing agent is applied and anaesthesia is given to minimise the pain. Firstly, ultrasound, X-ray and CT-scan are performed to provide the surgeon with exact details on where to insert the needle. Once the needle is placed on the exact location, the surgeon takes a chunk from the tissues with the needle. After the chunk is obtained, it is sent to the laboratory for examination with a microscope.
The surgeon or the clinician will monitor the pulse, blood pressure, and temperature for 6 to 24 hours after the biopsy is performed, according to the condition of the patient. Once the doctor allows the patient to go home, he/she shall not lift any heavy weight or do rigorous exercises for at least 2 weeks. The patient should avoid certain medicines such as aspirin and blood-thinning medicines for at least 1 week or until the surgeon has instructed.
