A Soft Tissue Mass Biopsy evaluates any unexplained lumps or bumps that develop under the skin, in the fat, or deep inside a muscle.
Common Indications for Soft Tissue Mass Biopsy
Your doctor may request this procedure if you have:
- A new or growing lump anywhere on your body (arms, legs, back, or abdomen).
- An unclear mass found on an MRI or ultrasound that needs to be identified as a benign cyst, a collection of fat (lipoma), an infection, or something requiring further treatment.
What happens during the procedure?
If the mass is close to the surface, the doctor will use an ultrasound to guide the needle. If the mass is located very deep inside the body, they will use a CT scanner. The live images allow the doctor to map a safe path for the needle, avoiding any important nerves or blood vessels. Once the area is numbed, the needle is inserted, and a small sample is retrieved.
Do I need to prepare?
This depends on where the lump is located. If it is deep and requires mild sedation, you will be asked to fast. For superficial lumps where only local numbing is needed, no special preparation is required.
How long does it take?
The biopsy usually takes around 30 minutes to an hour.
Will it be painful?
The local anesthetic ensures the process is not painful. You will feel pressure, and you might experience some bruising and mild aching for a day or two, which can be managed with an ice pack.
Conclusion
A Soft Tissue Mass Biopsy is a precise and minimally invasive way to figure out what a lump is made of. The imaging guidance guarantees the sample is taken accurately, providing answers without the need for immediate surgery.
