Some Common Knowledge On Enlarged Lymph Nodes


Found Some Common Knowledge!

It is common knowledge that an enlarged lymph node usually means there is an infection in the area of the lymph node and the body is doing what it was designed to do, which is fight it off. Bacteria, viruses, debris, cancer cells, and other foreign substances that are in the lymph are filtered through the nodes.

When the nodes become overwhelmed they will begin to swell and enlarge. They can also become painful. The node will reduce in size when the infection has run its course or responds to treatment.

In the event of other health issues, it will remain large until treated successfully.

Harmless Swollen Lymph Nodes in the Body

There are 500-700 lymph nodes in the body and many of them will swell unnoticed as they do their job of protecting the body from harmful debris that is traveling through the body. The white blood cells will reproduce to fight off infections and when they are successful they will return to normal numbers and the swelling will be reduced. The white blood cells are known as lymphocytes. Harmless causes of enlarged lymph nodes include the following:

  • Minor bacterial
  • Mild viral infection
  • Some fungi

When the lymph node remains swollen and there are other health problems or symptoms, there could be a more serious cause for the swelling

Enlargement from Serious Health Issues

Not all lymph nodes will shrink down to their normal size, which is the size of a pea. Some will remain swollen and be an indicator there may be a serious health issue that will need to be addressed. Due to the seriousness of cancer, if that is the cause of a lymph node that remains inflamed, a medical professional should examine the node and do tests to determine the cause. Only a healthcare professional can accurately diagnose the cause of the swelling.

Some of the serious health issues:

  • Cancer
  • MRSA
  • Lymphoma
  • Syphilis

Some of the less serious causes include:

  • Chicken pox
  • Skin infection
  • Alcoholism
  • Cold
  • Infected tooth

Most of the time swollen lymph nodes are nothing to be concerned about, it is just the immune system doing its job. When there are other symptoms, medical care should be sought.

Schedule a Doctor Appointment

When a lymph node remains enlarged for over two weeks, is painful to the touch, hard, or the skin is red or inflamed an appointment with the doctor should be scheduled and the node should be checked by a doctor. Other indicators that a doctor should examine a lymph node include night sweats, weight loss, fatigue, and prolonged fever.

Relief from painful lymph nodes can be relieved with compresses and over the counter pain relievers.


How Do Allergies Affect the Lymph System?

allergiesIn some cases, the body’s immune system, which comprises the lymphatic system, can overact to certain allergens such as pollen, certain medicines/chemicals, and even certain foods. When the body notices an allergen for the first time, it normally produces the necessary antibodies including IgE antibodies and B memory cells to fight it. However, when the same allergen appears again, the body is likely to respond by releasing excess antibodies to fight it, especially the IgE antibodies that attach themselves to mast cells and trigger the production and release of histamine, which eventually causes inflammation in certain parts of the body. It is probably important to note that for some people, the release of histamine and its subsequent inflammatory action can lead to anaphylactic shock, which is a life-threatening condition.


Allergies compromise the lymph system in the following ways:

  • Limit the ability of the lymph system to collect and transport tissue fluids from various body tissues to the blood stream.
  • Affect the supply of plasma proteins to the bloodstream.
  • Affect the transportation of digested fats to the blood stream.
  • Interfere with the manufacture of vital antibodies in the lymph system, and consequently affects the effectiveness of the entire immune system.
  • Compromises the ability of the lymphatic system to put up an effective defense against infections and harmful micro-organisms in the body.


  • It is important to establish which foods and substances you are allergic to and avoid them in order to avoid compromising your immune system. Some of the common symptoms of allergic reactions that you should look out for include wheezing, itchy eyes, running nose and itchiness in the eyes. However, symptoms of allergic reactions may vary depending on various factors including the particular allergen, the quantity of the allergen ingested or inhaled and how the immune system reacts to the allergen.
  • ¬†Although allergies are more common in children, adults too are susceptible to allergic reactions. Therefore, it is important to be aware of allergies that run in your family and take precautionary measures to avoid compromising the ability of your immune system to function effectively development of allergies.


Once you establish that you are allergic to certain substances, you should avoid such substances in order to protect your overall health. In case you have a history of life threatening reactions to allergens such as anaphylactic shock, ensure you see a doctor immediately if you ingest or inhale an allergen.


Important Facts And Details About Cancer In The Lymph Nodes

The lymph nodes can be considered as parts of the lymphatic system. The lymphatic system works in order to boost the body’s immune system.

These nodes are responsible on storing the lymphatic fluid and a certain type of white blood cell called the lymphocytes. These small structures help the body by fighting off bacteria and infections.

Unfortunately, cancer can also attack the lymph nodes. Because of this, it is important for everyone to be aware of the different facts and details about cancer in the lymph nodes.

Understanding Lymphoma

Lymphoma is the medical term for cancer in the lymph nodes. This is actually one of the most common types of cancer, which is also classified as Hodgkin’s or Non-Hodgkin’s lymphoma. Hodgkin’s lymphoma is actually treatable as long as it is detected early. This type of cancer is very common among young adults and as well as some seniors. Experiencing lymphoma can be very dangerous since it is very easy for the cancer cells to spread to different tissues and organs of the body through the lymphatic system. Because of this, early detection and management is vital in order to avoid the condition from worsening.

What are the Risk Factors?

There are several risk factors that can lead to the development of cancer in the lymph nodes. One of these is infection, such as the hepatitis C, HIV, and as well as the Epstein-Barr virus. Aside from infection, the American Cancer Society also mentioned that people aged 60 and above are also placed at high risk for this type of disease.

Discovering the Symptoms

Lymphoma can cause the body to produce different types of symptoms. Some of these manifestations include:

  • swelling of the nodes
  • high fever
  • night sweats
  • unexplained weight loss
  • coughing and problems in breathing
  • fatigue
  • persistent weakness
  • unnatural abdominal pain

If these symptoms are observed, it is necessary for people to visit their physician right away in order to diagnose and treat the condition.

How Does It Spread

Lymphoma can be experienced whenever the lymphocytes begin to mutate abnormally. The condition can also worsen when the cancerous cells spread to the different parts and organs of the body. Once the cancer cells have spread throughout the system, it may already be difficult to treat the problem.


These are just some of the common details and facts that people should know about cancer in the lymph nodes. Cancer is indeed a very difficult problem to solve. Aside from this, the tests and procedures involved in treating this disease can be very costly. This is the reason why people should always take care of their health and body.
