What is a biopsy? Let's learn about it simply!

When a doctor tells you that you need to have a biopsy, you may feel a little scared and nervous, right? You may think things like, "Oh my God, what is this going to do? Is it a serious illness?" But a biopsy is actually not something that scares us most of the time. It is a very important test that helps doctors diagnose a disease or get a clear understanding of a certain condition. Let's talk about this in a little more detail today, in Sinhala that you can understand.

What exactly is a biopsy?

Simply put, a biopsy is a very small sample of tissue or cells from your body that is taken for testing. Imagine that your doctor suspects that something is wrong or abnormal somewhere in your body. They take a small sample of urine from that area and send it to a laboratory. There, a pathologist (often called a pathologist) takes the sample and looks at it under a microscope . This allows them to magnify even the smallest cells thousands of times. Like a detective, they can tell what is really going on there by looking at these cells. You may have heard of a skin biopsy. But not only the skin, but also internal organs such as the kidneys, lungs, and muscles can be biopsied.

Most importantly, a biopsy allows doctors to take a closer look at what's going on inside. This can help them make a diagnosis and determine the best treatment.

Why do we need to do a biopsy?

There are many reasons why a biopsy may be done. It is important to remember that this is not always done to look for cancer.

• Confirm a disease: If a doctor sees certain symptoms or suspects something through other tests (for example, an X-ray or an ultrasound scan), a biopsy can help confirm exactly what it is.
• To know if it's cancer or not: Of course, if there is a suspicion of cancer, a biopsy is essential to confirm it. Also, if it is cancer, it helps to know things like what type it is and how far it has spread.
• Identify Infections : Sometimes bacteria , viruses , orBiopsies are also used to diagnose infections caused by things like fungi .
• Identify inflammatory conditions: A biopsy can also help determine the cause of a condition (inflammation) such as persistent swelling or redness in a part of the body.
• See if it responds to treatment: Sometimes, after starting treatment for a certain disease, a biopsy is performed to see if the treatment is having the right results.

For example, if you have a new spot on your skin that looks a little different, is getting bigger, or is changing color, your doctor may suggest a small biopsy. Or, if you have persistent stomach pain, they may take a small sample from inside your stomach during an endoscopy.

Are there types of biopsy?

Yes, there are different ways to perform a biopsy. It depends on factors such as where in the body the sample is to be taken and what condition is suspected. Let's look at some of the main types:

Skin Biopsy

This is the most common type of biopsy. It is done if there is something suspicious on the skin, such as a spot, lump, or lesion.

• Shave Biopsy : In this, a thin layer of the skin is removed by scraping it off.
• Punch Biopsy: A small, cylindrical piece of skin is removed using a small, circular knife-like instrument (similar to a puncher that punches holes in paper).
• Excisional Biopsy: In this procedure, the entire suspicious lump or spot is cut out and removed. A small incision may be made.

Needle Biopsy

In this, a special needle is used to take a sample from an organ or lump inside the body.

• Fine-Needle Aspiration (FNA): This involves using a very thin needle and syringe to remove a small amount of cells. This is often done for things like thyroid nodules .
• Core Needle Biopsy (CNB): This involves using a slightly larger needle than FNA to take a small cylindrical piece of tissue (a core). This method is used to take samples from organs such as the breast , liver, and kidney.

Often, when performing these needle biopsies, an ultrasound scan or CT scan is used to help the doctor find the exact location. This is called an image-guided biopsy.

Endoscopic Biopsy

An endoscope is a flexible tube with a small camera and light attached to it. It is inserted through a natural opening in the body (e.g., mouth, nose, or anus) to view internal organs.

• When examining the digestive tract (intestines, stomach) during a ``Gastroscopy`` or ``Colonoscopy``, a small piece of tissue may be taken from a suspicious area.
• Samples can also be taken this way when performing a bronchoscopy to examine the lungs.

Surgical Biopsy

Sometimes, if it is difficult to obtain a sample using other methods, or if a large sample is needed, a minor surgical procedure may be required to take a biopsy.

• Incisional Biopsy: In this, only a piece of the suspicious area is cut out and removed.
• Excisional Biopsy: In this, the entire lump or suspicious area is cut out and removed (this is similar to a skin biopsy).

Bone Marrow Biopsy

If there are certain blood problems (such as leukemia), this biopsy is done to examine the bone marrow. In this, a sample of bone marrow is taken from a large bone, such as the hip bone.

What should we know before a biopsy?

Your doctor will explain the procedure to you before performing a biopsy, but there are a few things you should know:

• Tell your doctor about all the medications you are taking: Some medications (especially blood thinners, such as aspirin and warfarin) may need to be stopped a few days before the biopsy. Also, tell your doctor about any allergies you may have.
• Tell your doctor about any other medical conditions you have: If you have any conditions such as diabetes mellitus, heart conditions, or bleeding disorders, your doctor should be aware of these.
• Some biopsies may require you to stop eating (fasting) before the procedure. Your doctor will advise you about this.
• It is a good idea to have someone with you on the day of the biopsy, especially if you are going to be given some kind of anesthesia. You may not be able to drive.
• Don't be afraid, ask questions: If you have any doubts or fears, ask the doctor or nurse about it.

How does the biopsy feel? Will it hurt?

This is a question that many people ask. Doctors always try to make you as comfortable as possible during this test. Therefore, anesthesia is given to reduce or eliminate pain during the biopsy.

• Local Anesthesia:This involves giving a numbing medicine (in the form of an injection) only to the area where the biopsy is being done. It's like numbing your gums before a tooth is extracted. You are conscious, but you don't feel it. This is often given for things like skin biopsies and FNA.
• Sedation: This will make you feel a little sleepy. You will feel relaxed and may not remember having the biopsy. This is used for things like endoscopic biopsies.
• General Anesthesia: This puts you completely to sleep. This is given for major procedures such as surgical biopsies.

So, you may feel a small stinging sensation when the numbing medicine is given. Most of the time, you won't feel much pain afterward. However, you may feel a slight pressure or pulling sensation. If you have any discomfort, tell your doctor right away. The time it takes to do a biopsy varies depending on the type of procedure being done. A skin biopsy can be completed in a few minutes. Some needle biopsies can take a little longer (about 30-60 minutes).

What happens after the biopsy?

After the biopsy is complete, the area is covered with a small bandage.

• Pain: Once the numbness has gone, you may feel a little pain, like a bruise. Your doctor may recommend taking a simple painkiller (e.g. Paracetamol).
• Aftercare: Your doctor or nurse will tell you how to keep the biopsy site clean, how to change the bandage (if necessary), and may also tell you to keep the area dry for a few days.
• Results: The sample is sent to the lab for testing, and it can take a few days (maybe a week or two) for the report to arrive. This varies depending on the type of biopsy and the complexity of the test. When the results are in, the doctor will call you and explain them.

What can we learn from a biopsy report?

A biopsy report is a description written by a pathologist after examining the sample. This includes looking at many things, such as the shape, size, and arrangement of the cells.

• Normal or Abnormal: This tells you whether the cells are normal or if there is something different.
• Cancer or not (Benign or Malignant): If it's something like a lump, you can tell whether it's benign (non-cancerous - `Benign`) or malignant (cancerous - `Malignant`).
• Other information: If it's cancer, the type, how aggressive it is, and possibly genetic changes may also be included in this report. All of this is very important for planning future treatment.

The most important thing is to discuss and understand the biopsy report thoroughly with your doctor.You may not understand the medical terms in the report. So, ask questions to the doctor and get a clear understanding of your condition.

Are there any risks to a biopsy?

Like any medical procedure, a biopsy can carry some risks. However, most of the time, a biopsy is a very safe procedure. Complications that can occur are usually minor and easily managed.

• Bleeding: There may be some bleeding from the biopsy site. Most of the time, this stops on its own.
• Infection: Rarely, the biopsy site can become infected. The key to preventing this is to keep the area clean. If an infection occurs, it can be treated with antibiotics.
• Pain or discomfort: There may be some pain or bruising at the biopsy site for a few days.
• Scar: After some biopsies (especially excisional biopsies of the skin), a small scar may remain.
• Damage to other organs: This is very rare, especially with deep needle biopsies. But doctors use technologies like ultrasound to reduce this risk.

Your doctor will tell you about these risks in advance. If you have any questions, don't be afraid to ask.

So, the final things to remember (Take-Home Message)

Okay, so these are the most important things to keep in mind from what we've talked about:

• A biopsy is a very important test that helps in diagnosis, but it is not something to be afraid of.
• It involves taking a small sample of tissue or cells from the body and examining them under a microscope.
• There can be many reasons for a biopsy; it's not always to look for cancer.
• There are several types of biopsy, and your doctor will decide which method is best for you.
• Anesthesia will be given to make you feel comfortable during the biopsy.
• It may take a few days for the results to come back. When the results come back , talk to your doctor carefully and understand them.
• The risks of a biopsy are very low.

Remember, a biopsy is a way to find answers to questions. The information you get will determine the best treatment for you. So, if your doctor suggests a biopsy, don't be afraid to do it, know the information you need, and go for it. I wish you a speedy recovery!
