What should you know about a sono-guided biopsy?

Sono is short for sonography, another name for ultrasound. The clinician uses a probe on the skin to create live images and chooses a safe path to the target. After cleaning and numbing the area, a biopsy needle is guided through the skin and small tissue samples are collected. Several samples may be taken so the laboratory has enough material for diagnosis and additional testing.

The sample may be examined under a microscope and may undergo immunohistochemistry or genomic tumour profiling when those tests could clarify the tissue type or guide treatment. Ultrasound guidance does not itself determine whether a finding is cancer; the pathology report provides that assessment.

Tell the team about blood-thinning medicines, bleeding problems, allergies, pregnancy, and previous reactions to local anaesthetic. Follow instructions about eating, drinking, and medicines. Arrange practical support if the biopsy is in a location that may make driving or lifting uncomfortable. Mild soreness or bruising can occur; keep the dressing and activity instructions provided by the clinic.

Contact the biopsy service for bleeding that does not settle with firm pressure, increasing swelling, spreading redness, fever, worsening pain, or drainage from the site. Seek urgent help for fainting, severe weakness, chest pain, or breathing difficulty. The urgency also depends on the body area sampled, so follow the location-specific instructions you were given.

Ask why ultrasound guidance is suitable, how many samples are planned, when normal activities can resume, and when the pathology report is expected. Ask whether the tissue may need additional stains, imaging, genomic testing, or review by another specialist.
