Why Lymph Nodes Are So Important & What Happens When They’re Removed
Tucked away throughout your body is a network of small, bean-shaped structures that act as the vigilant gatekeepers of your health. These are your lymph nodes. For most people, they go unnoticed unless they swell up during an infection, signaling that the body is fighting off an invader. For individuals diagnosed with breast cancer, however, lymph nodes suddenly take on a profound and critical significance. They become a central focus of diagnosis, treatment, and long-term recovery.
Understanding the importance of your lymph nodes is the first step in navigating the journey after breast cancer surgery. When these nodes are removed, it's a medically necessary step to ensure your safety and prevent the spread of disease. Yet, this removal is not without consequences. It permanently alters a vital bodily system, leading to potential long-term effects that require awareness and proactive care.
This comprehensive guide will delve into the crucial role lymph nodes play in your body. We will explain why they are so pivotal in staging and treating breast cancer and detail the physical repercussions that can occur when they are removed. We’ll explore conditions like lymphedema and axillary web syndrome, and most importantly, discuss how specialized therapies such as oncology lymphatic massage can empower you to manage these changes, reduce risks, and reclaim your quality of life after surgery.
What Are Lymph Nodes and What Do They Do?
Imagine your lymphatic system as a complex, city-wide security and waste management service operating within your body. This network is made up of vessels that carry a clear fluid called lymph, and strategically placed along these vessels are hundreds of lymph nodes. These nodes are the command centers and filtration plants of the system.
Each lymph node is a powerhouse of immune activity. Their primary functions include:
Filtering Lymph Fluid: Lymph fluid circulates throughout the body, collecting waste products, excess fluid, bacteria, viruses, and other cellular debris from the tissues. Before this fluid is returned to the bloodstream, it passes through multiple lymph nodes. Inside the nodes, specialized immune cells like lymphocytes (T-cells and B-cells) and macrophages identify and destroy these harmful substances.
Activating the Immune Response: When a lymph node detects a threat, such as an infection or cancer cells, it triggers an immune response. It swells as it ramps up the production of white blood cells to fight the invader. This is why you might feel swollen glands in your neck when you have a sore throat.
Trapping Cancer Cells: For cancer patients, this function is critical. If cancer cells break away from a primary tumor, they can enter the lymphatic vessels and travel through the system. The lymph nodes are the first line of defense, designed to trap these malignant cells and prevent them from spreading (metastasizing) to other parts of the body.
The lymph nodes located in the armpit, known as the axillary lymph nodes, are particularly important in breast cancer because they are the first to drain the breast and arm area. This makes them the most likely place for breast cancer cells to travel first.
Why Lymph Node Removal is Part of Breast Cancer Surgery
When a surgeon operates to remove a breast tumor (via lumpectomy or mastectomy), they must also determine if the cancer has started to spread. Examining the axillary lymph nodes is the most accurate way to do this. This process, known as staging, helps doctors understand how advanced the cancer is and determine the best course of treatment following surgery, such as chemotherapy or radiation.

There are two primary surgical procedures for evaluating and removing lymph nodes:
Sentinel Lymph Node Biopsy (SLNB)
This is the preferred and less invasive method for patients with early-stage breast cancer. The "sentinel" node is the first lymph node (or group of 2-3 nodes) that receives lymph drainage from the tumor. A surgeon injects a special dye or radioactive substance near the tumor, which travels through the lymphatic vessels to the sentinel node, making it identifiable. The surgeon then removes only these few sentinel nodes for examination by a pathologist. If they are clear of cancer, it is highly probable the cancer has not spread, and no further nodes need to be removed. This greatly reduces the risk of long-term side effects.
Axillary Lymph Node Dissection (ALND)
An ALND is a more extensive procedure performed if cancer is found in the sentinel nodes or if the cancer is more advanced. During an ALND, a larger number of axillary lymph nodes (typically between 10 and 40) are removed to clear the area of as much cancer as possible. While medically crucial, an ALND is significantly more disruptive to the lymphatic system, creating a major roadblock in the fluid drainage pathway for the entire arm, chest, and shoulder on that side.
The Consequences of Removing Lymph Nodes
The removal of lymph nodes, whether a few or many, permanently changes your body's "plumbing." The lymphatic vessels that once flowed through the removed nodes are cut, and the filtering capacity on that side of the body is forever diminished. Your body will attempt to compensate by creating new, smaller pathways for the lymph fluid to travel, a process called collateral circulation. However, these new routes are often less efficient than the original ones.
This disruption is the underlying cause of several well-known and challenging complications for breast cancer survivors. The risk of these complications is directly related to the number of nodes removed and is often amplified by subsequent treatments like radiation, which can cause further damage and scarring to the delicate lymphatic structures.
To understand and support lymphatic health after surgery, consider the benefits of oncology-sensitive lymphatic therapy.
Understanding Lymphedema: A Lifelong Risk
Lymphedema is the most well-known and feared complication of lymph node removal. It is a chronic and progressive condition caused by an accumulation of protein-rich lymph fluid in the body's tissues. When the lymphatic system is compromised and cannot adequately drain fluid from an area, the fluid builds up, causing swelling.
After breast cancer surgery, lymphedema typically affects the arm, hand, chest, or back on the side of the operation. It can manifest shortly after surgery or, in many cases, develop months or even years later. The risk is lifelong.
Early signs of lymphedema that every survivor should know:
A subtle feeling of fullness, tightness, or heaviness in the arm or hand.
Jewelry, such as rings or watch bands, feeling tighter than usual with no weight gain.
Visible swelling, which may be "pitting" (leaving an indent when pressed).
Aching, tingling, or discomfort in the limb.
Decreased flexibility in the fingers, wrist, or elbow.
Hand swelling after breast cancer surgery or arm swelling after mastectomy.
It is crucial to act on these early signs. When left untreated, lymphedema can worsen, leading to significant limb size increases, hardening of the tissue (fibrosis), reduced mobility, and a heightened risk of serious skin infections like cellulitis. Working with a lymphedema massage therapist is a cornerstone of both managing existing lymphedema and performing lymphedema risk reduction therapy.

Axillary Web Syndrome (Cording): The Tight Ropes
A few weeks or months after surgery, some survivors may feel tight, painful, rope-like cords running from their armpit down the inside of their arm. This is Axillary Web Syndrome (AWS), also known as cording. These cords are thrombosed (clotted) and scarred lymphatic vessels that have become hardened due to the surgical trauma.
Cording can severely restrict your range of motion, making it painful to lift your arm to do everyday tasks like brushing your hair or reaching into a cabinet. While it can be alarming, the good news is that axillary web syndrome treatment is highly effective. A trained therapist can use gentle massage and stretching techniques to release the cords and restore mobility, often providing significant relief in just a few sessions.
Post-Surgical Fibrosis and Scar Tissue Complications
All surgery creates scar tissue as the body heals. Following a mastectomy or lumpectomy, and especially after radiation, this scarring process can become excessive, leading to fibrosis—the development of hard, dense, fibrous tissue.
This hard scar tissue after breast cancer can cause a number of issues:
Post-Mastectomy Shoulder Tightness: Scarring around the shoulder can tether the skin to the muscle, severely limiting movement and causing pain.
Tight Chest After Radiation: Radiation can cause progressive fibrosis in the chest wall, creating a restrictive, "straitjacket" feeling that can even make deep breathing difficult.
Nerve Pain: Scar tissue can entrap or put pressure on nerves, leading to chronic pain, numbness, or tingling.
Specialized fibrosis massage therapy is designed to address these issues. A therapist can use manual techniques to soften and mobilize the scar tissue, releasing adhesions and improving tissue flexibility.
Proactive Care: The Role of Oncology-Sensitive Lymphatic Therapy
Hearing about these potential complications can be daunting, but it is important to remember that you are not helpless. Proactive, specialized care can dramatically improve your recovery and reduce your long-term risks. This is the purpose of oncology-sensitive lymphatic therapy.
This is not a standard massage. It is a highly specialized field of manual therapy provided by an oncology-trained lymphedema therapist who has in-depth knowledge of cancer, its treatments, and the intricate workings of the lymphatic system. They are trained to work safely with a compromised system to promote healing and prevent harm.

Manual Lymphatic Drainage (MLD) After Lymph Node Removal
Manual Lymphatic Drainage (MLD) is the primary technique used in post-cancer lymphatic massage. It is a very gentle, non-invasive skin-stretching technique that manually stimulates the lymphatic system. The therapist uses precise, rhythmic hand movements to redirect stagnant lymph fluid away from the at-risk, congested areas and toward healthy lymph node groups that can process it effectively.
A session of lymphatic massage after lymph node removal involves a specific protocol. The therapist will first work on clearing the central lymphatic pathways in the neck and trunk to create a "drain." Then, they will use meticulous sequences to encourage fluid from the affected arm or chest to move across the body to the unaffected armpit or down toward the inguinal (groin) lymph nodes.
The benefits of gentle manual lymphatic drainage are numerous:
Reduces post-operative swelling and bruising.
Helps manage and reduce lymphedema.
Decreases feelings of pain, heaviness, and tightness.
Promotes the formation of new lymphatic connections.
Induces deep relaxation and calms the nervous system.
Early intervention with post-surgical lymphatic drainage can begin as soon as your surgeon gives you clearance. Starting this therapy early is one of the most effective strategies for preventing the onset of chronic lymphedema.
