What should you know about stereotactic vacuum assisted biopsy?

You usually lie or sit in a position that allows the imaging equipment to locate the area accurately. After local anaesthetic numbs the skin, the clinician makes a small opening and places the biopsy device. Suction helps draw tissue into the needle, and several samples can be collected without repeatedly inserting a separate needle. A marker may be left at the sampled site so it can be found on later imaging.

The samples go to a laboratory, where a pathologist examines the cells and may use additional tests to identify their features. A biopsy result can be benign, atypical or cancerous; the procedure itself does not determine the result. Bruising, swelling or tenderness can occur afterward.

Tell the clinic about blood-thinning medicines, allergies, pregnancy possibility and difficulty staying in position. Wear supportive clothing and follow instructions about medicines before the appointment. Afterward, keep the dressing as directed, use a cold pack wrapped in cloth if advised and avoid strenuous activity until the team says it is suitable. Learn more about Biopsy and MRI Scan if further testing is discussed.

Contact the clinic if bleeding does not settle with firm pressure, redness spreads, pain worsens, the wound drains or you develop fever. Seek urgent help for heavy bleeding, fainting or breathing difficulty. A small bruise can be expected, but rapidly increasing swelling needs assessment.

Ask why this method is recommended, when the report is expected, whether a marker will remain, how medicines should be managed, and whether Immunohistochemistry or Genomic Tumour Profiling could be considered after the tissue diagnosis.
