Excisional biopsy

Overview

An excisional biopsy is a medical procedure where a doctor removes an entire lump or abnormal area of tissue from your body so it can be examined under a microscope. It is done to find out whether the tissue is normal or if it shows signs of disease, such as cancer.

Yes, excisional biopsies are a standard diagnostic tool. They are performed thousands of times each year in the UK and around the world.

Anyone who has a lump or abnormal area that needs further investigation may have an excisional biopsy. It can be done on people of all ages, but is most common in adults who have suspicious growths found during screening or physical exams.

Symptoms

Common symptoms

• A lump or swelling that can be felt or seen on imaging
• A change in the appearance of a mole or skin lesion
• Persistent pain or discomfort in one area
• Unusual discharge or bleeding from a spot

Symptoms in children

• A lump that your child's doctor has asked to be checked
• Unusual growth that does not go away

Symptoms in older adults

• A new or changing lump, especially in the breast, skin, or lymph nodes
• Persistent fatigue, unexplained weight loss, or fever with a lump

Causes

Main causes

• To find out if a lump is benign (not cancer) or malignant (cancer)
• To diagnose an infection in a specific area
• To investigate an abnormal finding on an imaging test (like mammogram or ultrasound)

Risk factors

• Having a family history of certain cancers
• Being over 50 years old
• Having a previous abnormal biopsy result
• Smoking or heavy alcohol use

When to see a doctor

See a doctor urgently if:

• You notice a new lump or a change in an existing lump
• A mole or skin lesion changes in size, shape, colour, or bleeds
• You have persistent pain or swelling in one area

Book a routine appointment if:

• You have a family history of cancer and want to be screened
• Your doctor has recommended follow-up after an abnormal imaging test

Diagnosis

An excisional biopsy is both a diagnostic test and a treatment step because the entire abnormal area is removed. The tissue is then examined by a pathologist (a doctor who studies tissue) to give a final diagnosis.

Tests that may be done

• Physical exam of the lump or area
• Imaging tests like ultrasound, mammogram, or MRI before the biopsy
• Blood tests to check general health before the procedure
• The excisional biopsy itself

What to expect at your appointment

You will be given a local anaesthetic injection to numb the area. The doctor makes a small cut in the skin and removes the entire lump along with a small rim of healthy tissue. The cut is closed with stitches and covered with a dressing. The procedure usually takes 30 minutes to an hour. You can go home the same day.

Treatment

Treatment depends on the biopsy result. If the tissue is benign (non-cancerous), no further treatment may be needed. If it is malignant (cancerous), your healthcare team will discuss next steps, which often involve surgery, radiation, or medication. Never start any treatment without a confirmed diagnosis and a discussion with your doctor.

Self-care at home

• Keep the biopsy site clean and dry for 24–48 hours
• Follow your doctor’s instructions about bathing and dressing changes
• Take over-the-counter pain relievers like paracetamol (acetaminophen) if needed — ask your pharmacist, but do not take aspirin or ibuprofen unless your doctor says it is safe
• Avoid heavy lifting or strenuous activity for a few days

Medical treatments

If the biopsy shows cancer, your doctor will explain your options, which may include further surgery to remove more tissue, radiation therapy, chemotherapy, or targeted therapies. The choice depends on the type and stage of the cancer. For infections, antibiotics may be prescribed.

When is surgery considered?

If the biopsy shows cancer, surgery to remove additional tissue (wider excision) or nearby lymph nodes may be recommended. This is not always needed for very small or low-risk cancers.

Living with this condition

Recovery from an excisional biopsy is usually quick. Most people can return to normal activities within a day or two. You may have some bruising, swelling, or mild pain at the site. Stitches are often removed after 7–14 days. A small scar may remain.

Lifestyle tips

• Avoid smoking — it slows healing and increases risks
• Eat a balanced diet rich in fruits, vegetables, and protein to help recovery
• Stay hydrated
• Get plenty of rest

Diet and exercise

No special diet is needed. Light activity like walking is fine. Avoid heavy exercise for about a week or until your doctor says it is safe.

Mental health and emotional wellbeing

Waiting for biopsy results can be stressful and frightening. It is normal to feel anxious, worried, or overwhelmed. Talk to your healthcare team about your feelings. They can connect you with a counsellor or support group.

Prevention

You cannot always prevent the conditions that lead to a biopsy, but you can reduce your risk of cancer by not smoking, limiting alcohol, staying active, and protecting your skin from the sun. Regular health check-ups can help find problems early.

Vaccines

Vaccines like the HPV vaccine can prevent some cancers (e.g., cervical cancer) that might lead to abnormal growths, but they do not directly prevent the need for an excisional biopsy. Ask your doctor which vaccines are right for you.

Screening programmes

Screening tests like mammograms, cervical smears, and skin checks can detect suspicious areas before they are felt or cause symptoms. Early detection often means simpler treatment.

Complications

If left untreated

• If a cancerous lump is not removed, it may grow and spread to other parts of the body
• Delaying biopsy may mean missing a chance for early treatment
• Infections or abscesses may worsen if left undisturbed

Long-term outlook

Excisional biopsy is a very safe procedure. The results give you and your doctor clear information to plan the best next steps. If cancer is found, catching it early often leads to successful treatment. Many people who have an excisional biopsy for a benign lump can be reassured and need no further treatment. Your outlook is best when you follow your healthcare team’s advice.
