: Guided Soft Tissue Biopsy

: What This Test Is

: This is a tissue sampling procedure, not a blood test. A doctor uses imaging such as ultrasound or CT to guide a needle to a specific area of soft tissue, such as muscle, fat, or connective tissue, and removes a small sample. The sample is then sent to a pathology laboratory for examination.

: Why It May Be Done

: Your care team may recommend this procedure when imaging tests show a lump, mass, or area of abnormal soft tissue that needs to be identified. A biopsy can help distinguish benign changes from infection, inflammation, or other conditions. Your doctor will explain the specific reason it is being recommended for you.

: How to Prepare

: Preparation instructions vary depending on the location of the biopsy and your health history. You may be asked about medicines that affect bleeding, allergies, and prior imaging, and you may need to adjust food or fluid intake before the procedure. Follow the instructions your care team gives you.

: What to Expect

: The procedure is often done on an outpatient basis and may use local numbing medicine. You may feel pressure or brief discomfort during sampling. Afterward, the site is usually checked and you may receive instructions about activity, wound care, and when to expect results.
