A lymph node biopsy is a test to detect the presence of diseases in the lymph nodes. Lymph nodes are part of the immune system. They help in recognising and warding off infections. A lymph node biopsy is the extraction of lymph node tissue for examination under the microscope. The physician can either excise the complete node or acquire a sample from the enlarged lymph node.
How is lymph node biopsy performed-Before, during and after?
Before the surgery, the doctor may ask a few questions related to the patient’s medical history. He may ask if she is pregnant, if she is on any medications, if she has any allergies, or bleeding disorders, etc. The patient is advised to refrain from eating or drinking anything for some hours before the biopsy.
During the biopsy, the doctor will insert a needle directly into the lymph node to take a sample in a needle biopsy. Whereas in an open biopsy, the surgery is open, as the name suggests. The doctor will use a tracer to track the spread of cancer in a sentinel node biopsy.
Tenderness and pain can last for a few days after the surgery. The doctor may ask the patient to refrain from taking a shower for a few days after the surgery. In the event of any complications or signs of infection, consult the doctor immediately.

Risks and complications of lymph node biopsy
- Bleeding: There can be extra bleeding, leading to excess blood loss, in such a case the patient might need a blood transfusion.
- Numbness: Numbness can occur if the biopsy site is around nerves. It usually disappears within a few months.
- Infection: The incisions required for the surgery might get infected and cause further complications.
- Lymphedema: A condition in which the lymph vessels are unable to sufficiently drain lymph fluid from a part of the body, which leads to fluid buildup and swelling.
Who needs a lymph node biopsy?
The doctor may notice swollen lymph nodes on a routine examination. Swollen lymph nodes due to insect bites or infections generally do not warrant medical intervention. The doctor might suggest a lymph node biopsy in the case of persistent swelling or further growth. This test will help them look for signs of an immune disorder, chronic infection, or cancer.
If your doctor has recommended a lymph node biopsy, book an appointment to get a second opinion.

Frequently Asked Questions about Lymph Node Biopsy
According to research, around 34% of lymph node biopsies are positive for a disease. This can be misleading because it is vital to note that lymph node biopsies are only performed after persistent swelling and after the physician rules out other physiological causes such as minor infections.
A lymph node biopsy is typically an outpatient procedure, so the patient need not stay overnight at the hospital. The process is fairly simple and minor. Even though it might take 10-14 days for the incisions to heal completely and the pain to subside, the recovery time is less.
The patient might experience mild pain and will be prescribed medication to manage the same. There is also a possibility that the pain and tenderness will last for a week or a bit more. The physician might advise you to avoid baths or showers for a few days.
Inform the doctor about consumption of any medications, if any and any allergies to medicines or medical apparatus. Be active and aware of the procedure, communicate with the doctor, and ask questions, if any. Stop taking any blood thinners five days before the biopsy. Do not eat or drink anything several hours before the surgery.
While it depends on the type of lymph node biopsy the doctor opts for, usage of general anaesthesia is possible for the needle, open, and sentinel node biopsy. The patient can request the doctor to use it if she wishes to be unconscious during the procedure.
The body has around 600 lymph nodes as a part of its immune system, which protects against various diseases. While complications such as lymphedema (the risk of which is magnified with every node removed ) may arise after removing a lymph node, the patient can surely live after a lymph node removal.
No, lymph nodes do not grow back once removed. Lymph node removal can also lead to further complications, as the affected area where the lymph node exists cannot drain the lymph fluid. This can cause the fluid to back up and result in problems that can last a lifetime.
Chemotherapy is mainly used to treat cancers. The doctor might order a lymph node biopsy as a way of diagnosing cancer that may have spread in the lymphatic system. The patient will only need to undergo chemotherapy if the lymph nodes are positive for cancerous cells.
