Details.
A tissue sample is taken using a needle, with an ultrasound or CT scan used to guide the procedure. The area is cleaned with antiseptic wash and local anaesthetic is applied before sampling. A skilled radiologist discusses the procedure, risks and benefits. Samples are sent to a laboratory for examination. No specific preparation is required, but patients taking blood thinners, including aspirin or warfarin, or those with a heart valve replacement should discuss this with their doctor and inform the clinic when booking. A support person should drive you home after the biopsy. Take the day off work and avoid strenuous activity afterwards. The procedure takes 30 to 60 minutes, with up to four hours of observation possibly required depending on the area biopsied.
