When is a Lymph Node Biopsy Necessary?

A lymph node is a group of cells located in the body’s tissue. It is a small, bean-shaped gland that helps to fight infection and diseases by filtering out foreign particles and substances, such as bacteria and viruses. Lymph nodes also play an essential role in controlling blood flow through the blood vessels throughout the body. This allows the immune system to fight off infections and other diseases if they arise. In cases where the lymph node becomes enlarged or spread to other body parts, a Somerville lymph node biopsy may be needed.

Lymph node biopsy is also used as a diagnostic tool for many other conditions, including;

Unexplained swollen lymph nodes

A swollen lymph node may be an early sign of cancer. Lymph nodes are part of the body’s immune system and can swell when infected or have fought off infection. If the swollen node persists for longer than three weeks, seek help from a specialist.

Breast cancer diagnosis

When a suspicious lump appears in the breast, lymph nodes may be removed for testing to determine if cancer is present. In this case, the biopsy is performed on one or more lymph nodes from where the lump was found.

Autoimmune diseases

Autoimmune diseases such as rheumatoid arthritis and lupus can cause inflammation in the body, leading to lymph node enlargement. In these cases, you may need a biopsy to determine whether there is an underlying cause for this inflammation and what treatment options are available for your specific condition.


Infection is one of the main reasons for a lymph node biopsy. If there is an infection in the neck or underarm, it has likely spread to a lymph node. This can be detected through imaging tests such as an ultrasound or CT scan.


The diagnosis of melanoma is usually based on the appearance of a mole or lesion, which can be found on the skin, mucous membranes, or internal organs. When the cancer has spread to the lymph nodes, a biopsy is needed to determine if it has metastasized or has spread to other body parts.


The most common cause of lymph node disease in the United States is lymphoma (cancer). Lymphoma can occur anywhere in the body but often affects the lymph nodes. These nodes are located throughout the body and help filter out waste products from cells. Lymphoma occurs when abnormal cells grow in these nodes and form tumors. In such a case, a lymph node biopsy is needed.


Lymph nodes are the glands in your body that help fight cancer. They’re located all over your body, including your neck, groin, and armpits. In some cases, lymph nodes can enlarge due to infection or cancer. If this happens, a lumbar lymph node biopsy exam is needed. The exam involves removing a group of lymph nodes from your lower back. The procedure helps determine if there’s cancer in a specific body area. For more information, link up with Somerset Surgical Associates, LLC.
