Lymph Node Biopsy

Tests And Procedures — On October 8, 2009 at 2:42 am

Lymph node biopsy is a testing procedure that involves the removal of a lymph node or a section of the lymph node intended to be sent for microscopic analysis. The lymphatic system comprises of lymph nodes that are connected by lymph nodes. The lymph nodes are responsible for the production of white blood cells or lymphocytes that help in combating infections. The presence of an infection triggers the swelling up of the lymph nodes leading to increased white blood cells production which endeavor to ambush the organisms that are eliciting the infection. The lymph nodes additionally attempt at ensnaring cancer cells.

How the Test is conducted

The test procedure is carried out in the operation theater in a hospital or in an outpatient-basis surgical facility. The sample could be taken in the following two ways, namely:

Needle biopsy.
Open biopsy.

Lymph node biopsy Needle biopsy – In this procedure, a needle is inserted inside the dubious lymph node. The patient is required to lie down on the inspection table. A thorough cleansing of the biopsy spot is done, following which the health care provider would administer a local anesthetic injection that would lead to deadened sensation in that area. The biopsy needle is then introduced into the node, and a sample is taken out. Localized pressure is applied on the spot to bring the bleeding to a halt and a dressing is done on the site.

Open biopsy – This is a form of surgical intervention for total or partial removal of the lymph node. One would be required to lie down on the inspection table. A tranquilizer might be administered to put the patient under sedation, if needed. A careful cleaning of the biopsy spot would be carried out followed by a local anesthetic injection administered to numb the area. Sometimes, general anesthesia is given that would put one to sleep and make the procedure pain-free. A tiny surgical incision would be made through which the entire lymph node or a section of it is removed. The site is sutured and a dressing done.

Subsequent to the sample being drawn, it is sent for lab analysis.

Preparation for the Test

One needs to keep one’s health care provider informed in case of the presence of any of the following:

Pregnancy.
Any form of drug allergy.
Bleeding issues.
The kind of medications being consumed inclusive of any form of supplements or herbal medicines.

One would be required to sign an assent form.

The experience of undergoing the Test

Subsequent to the administration of the local anesthesia, a jab mark and slight stinging sensation is felt in that area. The biopsy spot would continue to remain tender and painful for the next few days following the testing procedure.

Reasons for Performing the Test

The test is conducted to assist in determining the reason behind the swelling in the lymph glands. It might be conducted to detect whether the lymph node has either a malignant (cancer-forming) or benign (non-cancer forming) nature.

Normal Outcome

A swelling in the lymph nodes might be due to the presence of varied conditions that could range from mild version to cancer-forming kinds.

Deciphering an Abnormal Outcome

An irregular test result could be because of the presence of a host of conditions that might lie between quite mild to cancerous.

For instance, an enlargement in the lymph nodes might be because of:

Hodgkin’s lymphoma – A cancer affecting the lymph tissue originating in the lymph nodes, spleen, liver, bone marrow and other locations.
Infection.
Non-Hodgkin’s lymphoma – A lymphoid tissue cancer that involves the lymph nodes, spleen and other immune system organs.
Sarcoidosis – a disease of unidentified cause leading to inflammation due to the development of lumps known as granulomas that have a major effect on the different organs of the body.
