Lymph Node Biopsy
A medical procedure in which tissue is removed from a lymph node for further analysis.
Advanced and accurate diagnostics for your health
This test is performed to diagnose diseases such as cancer and to determine whether cancer cells have spread through the lymphatic system. Its results represent an important step in diagnosing and choosing the appropriate treatment for the patient.
Lymph node biopsy is highly effective, especially in determining the extent and staging of certain types of cancer.
The experience of pain during a lymph node biopsy may vary according to individual sensitivity and the type of biopsy performed.
The Procedure
Lymph node biopsy provides crucial information on disease progression and possible spread to other parts of the body, which is critical for clinical decision making.
The Results
The result of a lymph node biopsy can be positive if cancer cells are identified; or negative, suggesting the absence of malignant cells in the nodes analyzed.
The Specialist
Our pathology experts will thoroughly dedicate themselves to the analysis of the sample in order to provide a highly reliable result.
How is a Lymph Node Biopsy Performed?
Lymph node biopsy can be performed in different ways. Options include: fine needle biopsy, core needle biopsy, open (surgical) biopsy and sentinel lymph node biopsy; depending on the location and purpose of the biopsy. Each method has its own specific techniques and considerations, and is selected according to the diagnostic needs of the patient.
Fine Needle Biopsy
A thin needle is used to remove cells or tissue from a lymph node.
Core Needle Biopsy
Although similar to fine needle biopsy, this procedure uses a thicker needle to obtain a larger tissue sample.
Open Biopsy (Surgical)
An incision is made to remove one or more lymph nodes.
Sentinel Lymph Node Biopsy
The "sentinel" lymph node closest to the tumor is identified and removed.
How to prepare for a lymph node biopsy?
Before a lymph node biopsy, it is important to follow your doctor's instructions, which may range from dietary restrictions to medications, days before the test.
It is also crucial to inform the physician of any allergies or medical conditions in order to avoid complications.
Benefits
The benefits of lymph node biopsy include:
- Increased accuracy in the diagnosis of diseases such as cancer.
- Identification of the current stage of the disease.
- Planning the appropriate treatment according to the results obtained.
Cervical lymph node biopsy results
The results of a lymph node biopsy may vary. In the case of a negative result, it means that no pathological alterations were observed in the sample; therefore, there is an absence of cancerous cells. When the biopsy is positive, the presence of cancerous cells in the lymph nodes is confirmed.
Frequently Asked Questions
Lymph node biopsy can be performed under local or general anesthesia, depending on the type of biopsy and the patient's preference.
Recovery time after lymph node biopsy can vary, but generally a full recovery can be expected within a few weeks.
Side effects of a lymph node biopsy may include:
- Pain at the biopsy site.
- Swelling.
- Bruises.
- Risks associated with anesthesia and/or the procedure.
