Biopsy is a highly accurate procedure that examines the cause and extent of the lesion. Biopsy test is especially popular in diagnosing cancer to promptly prevent risks affecting the patient’s life.
You are viewing: What is a Biopsy?
Biopsy is a small, minimally invasive technique in which the physician will use a biopsy needle to cut or aspirate specimens from a suspected lesion of unknown nature for anatomical, bacteriological or clinical diagnosis. genetic diagnosis. Currently, this is a very effective and helpful support method for clinicians, aiming for standard treatment according to evidence-based medicine.
A biopsy is a medical procedure with high accuracy that helps diagnose most cancers. Types of imaging tests such as CT scan and X-ray can only help identify areas to be examined, but cannot distinguish between normal cells and cancer cells.
A biopsy is performed by taking a sample of tissue from any part of the body such as the skin, internal organs, or other structures. Then the patient sample will be examined under a microscope to diagnose the disease more accurately. The purpose of this test is usually directed to check for abnormalities in the function of a part of the body or abnormal cell structure changes such as tumors, swelling, tumours, etc.
Biopsy tests are often associated with cancer. Doctors use this test to check if abnormalities in the body are caused by cancer or other problems.
For example, if a woman has a lump in her breast, imaging tests will confirm the lump. A biopsy will help determine if it is breast cancer or any other condition.

2. Types of biopsy tests
Biopsy is classified into many different types, the doctor will choose based on the condition and suspicious areas on the patient’s body. Regardless of the type of biopsy, the patient will receive local anesthetic To relieve pain the area is taken. Here are some of the types of biopsies used in diagnosis including:
2.1. Bone marrow biopsies
Inside some large bones, such as the hip or femur, blood cells are produced by a spongy material called bone marrow. If the doctor suspects a problem with the blood, the patient will have a bone marrow biopsy.
Test bone marrow biopsy can diagnose cancerous and noncancerous conditions such as leukemia, anemia, infection, or lymphoma. The test is also used to check if cancer cells from another part of the body have spread to the bones.
The bone marrow is easily accessed using a long needle inserted into the hip bone. The inside of the bone cannot be numbed, so some people may feel a dull ache during the procedure.
2.2. Endoscopic biopsy
Endoscopic biopsies are used to access tissue inside the body to collect samples from organs such as bladder, Colonlung…
During the procedure, your doctor will use a thin flexible tube called an endoscope with a small camera and light. The doctor uses a video monitor to view images that make it easier to collect samples. After the procedure, the patient may feel some discomfort, gas, or a sore throat.
Laparoscopic biopsies can be done through small incisions in the body, or through organs including the mouth, nose, rectum, or urethra. The process usually takes between 5 and 20 minutes.
2.3. Needle biopsy
Needle biopsies are used to collect skin samples, or for any tissue that is easily accessible under the skin. There are different types of needle biopsies including:
Core Needle Biopsy: This test uses a large, medium-sized needle to access the central tissue core, for example removing tissue from the central core of a tumor inside the breast. Axial biopsy: This procedure is done for areas that can’t be felt, but seen through x-ray images such as X-rays or CT scans so the doctor can access specific areas, like the lungs, liver, or other organs.
Needle biopsies are used to collect skin samples, or for any tissue that is easily accessible under the skin
2.4. Skin biopsy
The doctor may order skin biopsies suspect if the patient has a rash, skin lesions, is suspected of a certain condition, is not responding to a doctor’s treatment regimen, or has no known cause.

Skin biopsies can be done using a local anesthetic, then removing a small section with a knife, or using a punch biopsy, a special instrument that punches a small hole through the top layers. of the skin to obtain a sample of the skin to be biopsied.
The skin biopsy sample will be sent to a laboratory to be tested for possible conditions such as infection, cancer, inflammation of skin structures or blood vessels.
2.5. Surgical biopsy
Your doctor will remove a small tissue sample to examine over the course of a few minutes to help guide further surgery or treatment.
In an excisional biopsy, part or all of the tumor may be removed to look for abnormal cells. Excisional biopsies are performed under local or general anesthesia, depending on the location of the tumor. This type of biopsy can be done for breast lumps.
Some of the effects of a biopsy test include:
Testing for infection: A needle biopsy can help determine if a patient has an infection, and what type of organism is causing it. Inflammatory testing: By examining cells, for example with a needle biopsy. , your doctor can determine the cause of the inflammation.
Sometimes, biopsies are also performed on transplanted organs to determine if the body is adapting to the transplanted organ.
Biopsy is a rather complicated technique, so doctors will only do biopsies after easier diagnostic techniques have been performed (X-ray, ultrasound, laboratory tests) that are still uncertain. sure disease. According to experts, viewing tissue or cells under the microscope always gives the most accurate diagnostic results and is very effective when determining the nature of a tumor: Benign tumor or malignant tumor?. Once it is determined that the tumor is malignant, the doctor will order a biopsy of nearby tissues to see if the tumor has metastasized or not, so that appropriate therapy can be given to the patient.
4. The process of performing a biopsy
Biopsy tests are usually done in a hospital, surgical center, or specialist’s office. To be able to perform a biopsy test, it is necessary to pay attention to the following stages:
4.1. Before performing the biopsy
The biopsy procedure may require some preparation on the part of the patient, such as avoiding eating or drinking for several hours prior to the test. Patients should tell their doctor about any medications and supplements they take. You may need to stop taking certain medications before the test, such as aspirin or nonsteroidal anti-inflammatory drugs.
Patients will be tested for blood and assessed for possible allergies to related substances. Depending on the type of biopsy, your doctor will give you more specific instructions on what to do before the procedure. The patient will need to sign a consent form to this test.
4.2. While performing a biopsy
The biopsied tissue samples will be sent to a laboratory and will be examined by a coroner. In the case of cancer, the examiner will need to determine if the sample is malignant or benign. If the case is malignant, they will evaluate how invasive or advanced the cancer is. As for benign cases, it will depend on the size of the tumor and whether there is a risk of becoming malignant or not, the doctor will give an appropriate solution.
4.3. After performing a biopsy
If a biopsy tissue sample is taken from an internal organ, the patient may need general anesthesia and an overnight hospital stay. The procedure to scrape a tissue sample from the inside of the mouth is usually not necessary anesthesiathe area may feel sore for a while.
If the biopsy sample was taken from a major organ, such as the liver or kidney, the patient may need to rest in the hospital for several hours before being able to go home. After a cervical biopsy or endometriumThe patient may experience light vaginal bleeding.
Possible risks include possible bleeding, testing in the wrong place, not taking enough samples which could lead to false results and the need for a repeat test. A study of the results of a test used in clinical trials found that only 5.2% of biopsies resulted in complications.
