How is the biopsy procedure done?
(Update: ) - Skin and soft tissue diseases
In fact, there is a sentence used before or after treatment that we hear a lot; parts must be taken. Here to the piece received biopsy we say. Let's see in what situations is a biopsy taken?
What is a biopsy?
In some diseases, it may be necessary to take samples from cells, tissues or organs to be examined in the laboratory in order to make a definitive diagnosis.
The name of this process is Biopsy (Biopsy, Biopsy, Receiving parts). The parts taken are important in terms of diagnosis, classification, stage and follow-up of the disease.
Why is it necessary to take a biopsy?
Biopsy is the only method to make a definitive diagnosis. No imaging method (x-ray, MR, CT, PET, etc.) is an alternative to biopsy. Imaging methods detect the presence of the disease.
Biopsy is very important, especially in terms of detecting whether the disease is benign or malignant.
However, never taking a biopsy alone does not show that something can be bad and should not cause you to worry.
For example, breast ultrasound or mammography can detect but is this mass benign (fibrocyst, fibroadenoma, fat necrosis, etc.), malignant (breast cancer) only and only biopsy can answer.
How is biopsy taken?
Removing some of the diseased tissue Incisional BiopsyIf the tissue or formation is completely removed together with the surrounding normal tissue. Excisional Biopsy is called.
Do not be afraid of the statement of taking part because most biopsy procedures are painless and low risk 🙂
When malignant formations are considered, excisional biopsy is especially preferred. In this case, it is important in normal tissues taken with the formation and Surgical Clinical Border is called. When the biopsy is examined, the cleanness of this border means that the abnormal formation is successfully removed.
Generally, regional anesthesia is used before biopsy and the procedure is performed painlessly.
Biopsy methods and types
There are many biopsy methods available according to the diseases. In all methods, tissue samples are taken using sharp tools. Before the procedure in biopsies taken from the skin local anesthesia with the area numbed.
Some types of biopsy are as follows:
- Needle Biopsy: is the most commonly used method.
- CT-guided biopsy: Biopsy is taken from the diseased tissue with the help of computed tomography
- USG-guided biopsy: Biopsy is taken from the diseased tissue with the help of ultrasound
- Bone Biopsy: In this method, a CT-guided biopsy is taken by an orthopedist.
- Bone Marrow Biopsy: A biopsy is taken from the pelvic bone with the help of a large needle. This method is especially
it is applied in blood cancers such as leukemia and lymphoma.
- Liver Biopsy: With the help of ultrasound, a biopsy is taken from the liver by passing through the skin with a needle.
- Renal Biopsy: With the help of ultrasound, a biopsy is taken from the kidney by passing through the skin with a needle.
- Aspiration Biopsy: A biopsy is taken by passing through the skin with the help of a fine needle. It is also called Fine Needle Aspiration Biopsy (FNAB). for example thyroid biopsy.
- Prostate biopsy: More than one needle biopsy is taken from the prostate with the help of an ultrasound probe from the anus (anal) area.
- Skin (Punch) Biopsy: It is the process of taking a full-thickness cylinder tissue sample from the lesioned skin with a disposable punch tool.
- CLO Biopsy: Endoscopy During the biopsy is taken from the gastric mucosa. Using the rapid urease test (CLO test) or by performing histopathological examination, the stomach is Helicobacter pylori whether it is investigated.
- Tru-cut biopsy: It is the most commonly used method in the diagnosis of breast lumps (cutting needle biopsy). The procedure is done using thick (3-4 mm) needles and a biopsy gun.
- Surgical Biopsy: Open (open) or closed (laparoscopic) surgical method is used for hard-to-reach tissues and organs.
What should be done after the biopsy is taken?
The parts taken are collected in special containers and solutions and sent to the laboratory.
After the biopsies are histopathologically examined macroscopically and microscopically by the pathologist, the results are sent to the doctor who follows you in a report.
The duration of the results may vary depending on the nature of the tissue taken (average 3-10 days).
