What is a biopsy?

A biopsy is a medical procedure in which a healthcare provider removes a small sample of tissue, cells, or fluid from the body to analyse for signs of disease. This sample, examined by a medical pathologist, helps diagnose or monitor various conditions, guiding effective treatment plans. Although the term “biopsy” often brings cancer to mind, providers use biopsies to analyse a wide range of medical conditions, including:

• Inflammatory conditions, like nephritis (kidney inflammation) or hepatitis (liver inflammation)
• Infections such as tuberculosis
• Immune-related disorders, like chronic pancreatitis
• Peptic ulcer disease
• Endometriosis

A biopsy is often recommended to investigate further when a physical examination or imaging reveals abnormal tissue—sometimes called a lesion, tumour, or mass. This sample can confirm whether cells are cancerous or identify other health issues causing tissue abnormalities.

While undergoing a biopsy might seem intimidating, most procedures are straightforward and involve minimal discomfort or risk. This essential diagnostic tool allows doctors to gain critical insights into your health and determine the best course of action for treatment.

Types of biopsies

Biopsies can vary based on the location and type of tissue being examined, as well as the purpose of the test. Here are some common types of biopsies:

1. Needle Biopsy:
   • Fine Needle Aspiration (FNA): A thin needle extracts small amounts of tissue or fluid. It is often used for thyroid, lymph nodes, and breast lumps.
   • Core Needle Biopsy: A slightly larger needle collects a core tissue sample, which is used for more profound tissues, such as those in the breast, liver, or prostate.
   • Image-Guided Biopsy: An image-guided biopsy combines an imaging technique—such as a CT scan, MRI, or ultrasound with a needle biopsy. This method allows healthcare providers to reach and sample areas that can’t be felt through the skin, such as liver, lung, or prostate tissues. By using real-time imaging, providers can accurately guide the needle to the precise location of concern.
2. Endoscopic Biopsy

   This type uses an endoscope, a flexible tube with a light and camera, to access internal organs. It is common for examining the gastrointestinal tract, lungs, bladder, and other internal sites. Biopsy tools attached to the endoscope collect tissue samples during procedures like colonoscopies, cystoscopies, or bronchoscopies.

3. Skin Biopsy
   • Excisional Biopsy: The entire abnormal tissue or lesion area is often removed for suspicious skin lesions or small lumps.
   • Incisional Biopsy: Only a portion of the abnormal tissue is removed for examination, often used for larger tumours or masses where removing the entire area isn't feasible.
   • Punch Biopsy: Commonly used in dermatology, a circular blade "punches" out a small, round sample of skin tissue. It’s effective for diagnosing skin conditions or diseases like melanoma.
   • Shave Biopsy: In this skin biopsy, a doctor shaves off a thin layer of skin to examine surface-level skin issues. This is often used for skin lesions and growths.
4. Bone Marrow Biopsy

   A needle extracts bone marrow tissue from the hip bone to diagnose blood-related disorders like leukemia, anemia, or lymphoma.

5. Surgical Biopsy
   • Open Biopsy: Involves a surgical incision to remove a tissue sample. Usually done under general anaesthesia and used for hard-to-access areas.
   • Laparoscopic Biopsy: A minimally invasive surgery that uses small incisions and a laparoscope (miniature camera) to view and sample abdominal or pelvic tissues.
6. Liquid Biopsy

   A non-invasive type that analyses blood or other bodily fluids to detect cancer cells, fragments of tumour DNA, or other biomarkers. This method is increasingly used for monitoring cancers and understanding tumour genetics.

Procedure Details

A biopsy involves carefully removing tissue, cells, or fluid samples from the body for closer examination, usually to help diagnose or monitor a medical condition. Here are the typical steps involved in different biopsy procedures:

1. Preparation
   • Pre-Procedure Instructions: Patients may be asked to fast or avoid certain medications that could increase bleeding risk before the procedure. The healthcare team will provide specific instructions based on the type of biopsy.
   • Consent: The healthcare provider explains the procedure, potential risks, and benefits, and the patient provides informed consent.
2. Anaesthesia

   Local or General Anaesthesia: Depending on the biopsy type and location, the provider may use a local anaesthetic to numb the area, or, for more complex procedures, general anaesthesia or sedation may be provided.

3. Sample Collection and Analysis

   Once the sample is taken, it’s sent to a pathology lab, where a pathologist examines it under a microscope. Depending on the findings, the pathologist may perform additional tests to aid diagnosis.

4. Post-Procedure Care
   • Monitoring and Recovery: After the biopsy, the patient may need to rest briefly and be monitored for any immediate side effects.
   • Instructions: Patients receive post-procedure care instructions, which may include guidelines on caring for the biopsy site, managing discomfort, and watching for signs of infection.
5. Results and Follow-Up

   The biopsy results may take several days to a week to receive. The provider will review these with the patient and discuss the next steps, which may involve further diagnostic tests, treatment planning, or monitoring.

Biopsies are generally safe, and while risks like bleeding or infection exist, these are typically minimal.

A biopsy is a medical procedure in which a small sample of cells, tissue, or fluid is removed for detailed examination by a pathologist. While being recommended for a biopsy can feel overwhelming, it’s essential to remember that it’s simply a diagnostic step to help identify or rule out health concerns, including cancer. Many biopsies reveal benign conditions or early-stage issues that can be managed effectively.
