What is Biopsy?

A biopsy is a medical procedure that involves obtaining a small tissue sample from the body for examination under a microscope. One of the biggest uses of biopsy includes diagnosing various conditions, including cancer, infections, and autoimmune diseases. Biopsies can be done using multiple methods, such as needle biopsy, surgical biopsy, or endoscopic biopsy. Results of biopsy guide treatment decisions and provide valuable information about the patient's health.

What are the Different Types of Biopsies?

The following are the different types of biopsies:

Needle Biopsy

Needle biopsy is a minimally invasive procedure to obtain tissue samples for examination. It involves the insertion of a thin needle through the skin to extract cells or tissue from a suspected area, such as a tumor or mass. Needle biopsies are commonly used to diagnose conditions like cancer.

Image-Guided Biopsy

Image-guided biopsy is a precise technique used to sample tissue from specific body areas under the guidance of medical imaging technologies like ultrasound, CT, or MRI scans. This method ensures accurate targeting of suspicious lesions or masses, reducing the risk of sampling errors and improving diagnostic accuracy. Image-guided biopsies are commonly used in the diagnosis and staging of various diseases, including cancer.

Endoscopic Biopsy

Having a family history of breast cancer, where one’s mother, sister, or daughter is diagnosed with it, can increase one’s risk of MBC.Endoscopic biopsy is a procedure that involves the use of a flexible tube with a camera and instruments at its tip, called an endoscope. It is inserted into the body through a natural opening or a small incision. It allows direct visualization and sampling of tissue from the digestive tract, respiratory system, or other organs. Endoscopic biopsies aid in diagnosing conditions like gastrointestinal disorders, lung diseases, and cancers.

Skin Biopsy

Skin biopsy is a procedure to obtain a small skin tissue sample for examination under a microscope. It is performed to diagnose various skin conditions such as rashes, moles, or suspected skin cancers. Different techniques for skin biopsy are punch biopsy, shave biopsy, or excisional biopsy, depending on the size and depth of the lesion. Results from a skin biopsy test help determine the appropriate treatment and management plan for the specific skin condition.

Bone Marrow Aspiration and Biopsy

Bone marrow aspiration is a medical procedure used to evaluate bone marrow fluid. Doctors insert a needle into the bone marrow cavity, typically the hipbone, to withdraw a small amount of liquid-containing marrow cells. This test helps diagnose blood disorders like leukemia, anemia, and infections. It is also used to monitor treatment response and evaluate bone marrow function.

Surgical Biopsy

A surgical biopsy, or biopsy operation, involves the surgical removal of a tissue sample for diagnostic examination. It is done under general anesthesia in an operating room. This method is used when a larger tissue sample is needed or other biopsy methods are not feasible. Surgical biopsies are commonly employed for diagnosing tumors, lymph node abnormalities, and other deep lesions.

Liquid Biopsy

It is a non-invasive diagnostic test that analyzes biomarkers, such as cell-free DNA, circulating tumor cells, or exosomes, in bodily fluids like blood or urine. It provides insights into various conditions, including cancer and infectious diseases, by detecting genetic mutations or other abnormalities. The procedure is a less invasive alternative to traditional tissue biopsies, enabling disease progression and treatment response monitoring.

Laparoscopic Biopsy

Certain testicular conditions that lead to hormonal imbalances Laparoscopic biopsy is a minimally invasive surgical procedure used to obtain tissue samples from organs within the abdominal cavity. It involves inserting a laparoscope and other surgical tools through small holes in the abdomen. Tissue samples are collected using specialized instruments and examined under a microscope to diagnose conditions such as liver disease, pancreatic cancer, or abdominal masses.

Punch Biopsy

It is a procedure where a cylindrical tool called a punch is used to remove a small tissue sample from the skin. It is commonly used to diagnose skin conditions such as rashes, moles, or skin cancers. The procedure is relatively painless, with minimal scarring. The sampled tissue is then examined under a microscope to provide diagnostic information.

Who does a Biopsy, and Who Analyzes the Sample?

A biopsy is generally performed by a trained healthcare professional such as a surgeon, dermatologist, gastroenterologist, or radiologist, depending on the types of biopsies and the body area requiring sampling. Once the sample is collected, it is sent to a pathology laboratory, where pathologists analyze it. Pathologists are medical doctors who specialize in examining tissues and cells under a microscope to make a diagnosis.

What are the Purposes or Uses of Biopsy?

The following are the most common purposes of biopsy:

Cancer Diagnosis

Cancer tumor biopsy is crucial in cancer diagnosis, allowing the collection of tissue or fluid samples for examination. Various biopsy techniques include needle, surgical, or endoscopic biopsies. Biopsy aids in identifying cancerous cells, determining tumor type, and guiding treatment decisions. Accurate diagnosis through biopsy helps oncologists develop customized treatment plans, evaluate disease progression, and monitor treatment response, improving patient outcomes and survival rates.

Identify Infection

Uses of biopsy also comprise the diagnosis of infections by extracting tissue or fluid samples from affected areas for analysis. This procedure is often guided by imaging techniques and aids in diagnosing infectious diseases such as tuberculosis and bacterial or fungal infections. Microscopic examination, culture, or molecular testing of biopsy samples help determine the causative agent, assess disease severity, and guide appropriate treatment strategies for patients.

Assess Organ Health

Assessing organ health by obtaining tissue samples for examination is another use of biopsy. It aids in diagnosing conditions like liver disease, kidney dysfunction, or heart problems, providing valuable information about organ function and structure. Pathologists analyze biopsy specimens under a microscope to evaluate cellular abnormalities, inflammation, or tissue damage.

Guide Treatment Decisions

Biopsy plays a vital role in guiding treatment decisions by providing crucial information about the nature and severity of diseases. The uses of biopsy also involve determining the specific characteristics of tumors, infections, or other conditions. This information allows for patient-specific treatment strategies, thereby optimizing therapeutic efficacy and improving outcomes.

What Happens Before - During - After Biopsy?

What Happens Before a Biopsy?

Before a biopsy, the doctor reviews the medical history and performs a physical examination. Depending on the types of biopsies, additional preparation may include fasting, discontinuing certain medications like blood thinners, or obtaining consent. Patients are informed about the procedure and potential risks.

What Happens During a Biopsy?

During a biopsy, the patient is positioned appropriately. The area under biopsy is cleaned and numbed with a local anesthetic. The doctor then uses specialized instruments to collect tissue or fluid samples. Depending on the types of biopsies, this may involve needle insertion, surgical removal, or endoscopic techniques. The doctors sent the samples to a laboratory for analysis.

What Happens After a Biopsy?

After a biopsy, the patient may experience mild discomfort or bleeding at the biopsy site. It can be managed with pressure and a bandage. The collected samples are sent to a pathology laboratory for analysis. The biopsy test timeline may depend on the types of biopsies. Biopsy test results are usually available within a few days to a week. Further treatment options may be discussed with the patient, depending on the findings.

Questions to Ask Your Health Care Team

Patients often ask about the uses of biopsy, its potential risks and costs, and what to expect during and after the procedure. They may inquire about any discomfort, recovery time, and restrictions afterward. Patients often require clarity on how the biopsy results will impact their diagnosis and treatment plan, including follow-up steps and possible alternative options.

Conclusion

A biopsy is necessary for diagnosing various conditions, including cancer and infections. It provides valuable insights into tissue structure and cellular abnormalities. The uses of biopsy include guiding treatment decisions and improving patient outcomes. It may involve a minimally invasive needle biopsy or a more invasive surgical procedure. Biopsies allow tissue samples to be obtained for precise diagnosis and tailored treatment strategies.
