Ultrasound guided biopsy

Overview

An ultrasound-guided biopsy is a procedure where a doctor uses ultrasound images to guide a thin needle to take a small sample of tissue from a suspicious area in your body. The sample is then sent to a lab to be checked for disease, such as cancer.

Yes, ultrasound-guided biopsy is a common and well-established procedure used in many hospitals worldwide.

It can be used for anyone who has a suspicious lump or abnormal area seen on an ultrasound or other imaging test. It is often used for breast, thyroid, liver, kidney, or lymph node biopsies.

Symptoms

Common symptoms

• A lump or mass that can be felt or seen on imaging
• An abnormal area found during a routine scan

Symptoms in children

• Swelling or lump that doesn't go away
• Unexplained pain or tenderness in one area

Symptoms in older adults

• New lump or growth that appears slowly
• Changes in an existing mole or skin spot

Causes

Main causes

• The biopsy is done to investigate the cause of an abnormal lump or imaging finding.
• It is often needed when a doctor suspects a condition such as cancer, infection, or inflammatory disease.

Risk factors

• There are no specific risk factors that increase the need for a biopsy; it is a diagnostic tool used when clinically indicated.

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency or urgent symptoms listed above after the biopsy

Book a routine appointment if:

• If you notice a new lump or change in your body that persists for more than a couple of weeks

Diagnosis

The ultrasound-guided biopsy procedure itself is a diagnostic test. The tissue sample is sent to a laboratory, where a pathologist examines it under a microscope to determine whether it is normal, benign, or malignant.

Tests that may be done

• Ultrasound scan to locate the target area
• Fine needle aspiration (FNA) or core needle biopsy to remove tissue
• Laboratory analysis of the tissue sample

What to expect at your appointment

During the procedure, you lie on an exam table. The doctor applies gel to your skin and uses an ultrasound probe to find the area. After numbing the skin with local anaesthetic, they insert a thin needle and take a small sample. You may feel some pressure but it is usually quick. Afterwards, you can go home with simple aftercare instructions.

Treatment

Treatment after a biopsy depends entirely on the results. If the biopsy shows a benign condition, you may not need any further treatment. If it shows cancer or another disease, your healthcare provider will explain the next steps, which may include surgery, medication, or other therapies.

Self-care at home

• Rest for the remainder of the day after the biopsy
• Apply an ice pack to the biopsy site to reduce swelling
• Avoid heavy lifting or strenuous exercise for 24 hours

Medical treatments

Any medical treatment, if needed, will be determined by the biopsy results and your overall health. Options may include medications, radiation, or chemotherapy, but your doctor will discuss these with you in detail.

When is surgery considered?

Surgery may be recommended if the biopsy confirms cancer or another condition that requires removal of the affected tissue. Your healthcare team will explain the specific procedure and recovery.

Living with this condition

Most people can return to normal activities the day after the biopsy. You may have a small bruise or soreness at the site for a few days. Care for the area as instructed by your nurse or doctor.

Lifestyle tips

• Keep the biopsy site clean and dry
• Do not soak in a bathtub, hot tub, or pool for 24 hours
• Watch for signs of infection as listed above

Diet and exercise

You can eat and drink normally after the procedure. Gentle exercise like walking is fine, but avoid heavy lifting or intense activity for 24 hours.

Mental health and emotional wellbeing

Waiting for biopsy results can be stressful and anxiety-provoking. It is normal to feel worried. Talk to your healthcare provider about your concerns, and consider reaching out to a counsellor or support group if needed.

Prevention

The need for a biopsy cannot be prevented because it is a response to an already existing lump or abnormal finding. However, paying attention to changes in your body and seeking medical advice early can lead to timely diagnosis.

Screening programmes

Routine health checks and screenings (such as mammograms or ultrasounds) may help detect abnormalities early, though they do not prevent the need for a biopsy.

Complications

If left untreated

• If a suspicious area is not biopsied, the underlying condition may go undiagnosed and could worsen.
• For example, a cancer left untreated can grow and spread.

Long-term outlook

The outlook after an ultrasound-guided biopsy is very good. It is a safe procedure with a low risk of complications, and it provides crucial information that guides your treatment. Most people recover quickly and without problems.
