Why are my pectoral lymph nodes swollen?
These lymph nodes may swell when there is an infection, especially in nearby areas such as the breasts or throat. Swollen lymph nodes can signal a serious underlying condition, such as cancer or an infection.
How many pectoral lymph nodes are there?
These are also known as the pectoral group. They can be located across the inferior border of the pectoralis minor muscle and the superior border of the pectoralis major muscle. There are usually 4-5 large nodes.
Where are lymph nodes located by breast?
The lymphatic system is a network of lymph nodes and lymph ducts that helps fight infection. Lymph nodes — found under the armpit, above the collarbone, behind the breastbone and in other parts of the body — trap harmful substances that might be in the lymphatic system and safely drain them from the body.
Where are the 3 most common places to find lymph nodes?
The body contains hundreds of lymph nodes. They form clusters around the body and are particularly prominent in areas such as the neck, armpit and groin and behind the ears.
What are the signs that you have a cancerous lymph node?

Do cancerous lymph nodes show up on CT scan?
CT scans are different than standard x-rays because they create a series of pictures taken from different angles and produce much clearer images. A CT scan of the chest or abdomen can help detect an enlarged lymph node or cancers in the liver, pancreas, lungs, bones and spleen.
Where are most breast cancers located?
(Eighteen percent of breast cancers occur in the nipple area, 11 percent in the lower out quadrant, and 6 percent in the lower inner quadrant.) ANY change in size, shape, texture or nipple that occurs in one breast only is more dangerous than if such changes happen simultaneously in both breasts in the same position.
What does a swollen lymph node in breast feel like?
An underarm lump that appears suddenly and feels rather large (think marble-sized), especially if you've been feeling ill, is most likely to be a swollen lymph node. This lump will usually be soft and moveable, and feel sore or painful. You may even notice some reddening of the skin around the lump.
Would a cancerous lymph node hurt?
This being said, leukaemia or lymphoma (another type of blood cancer) can cause painful lymph nodes on occasion. This is because they can grow big enough to press down on surrounding nerves or other organs, causing pain.
What was your first lymphoma symptom?
Lump or swelling in neck, throat, or jaw. Swelling of the lymph nodes is often the first thing lymphoma patients notice. Lymphoma can cause lymph nodes in the neck, throat, jaw, armpit, or groin to visibly swell.

Where are lymph nodes located? Lymph nodes are located throughout the body, including the neck, armpits, groin, around the gut, and between the lungs. Lymph nodes drain lymph fluid from nearby organs or areas of the body.
How many lymph nodes can you remove?
Removing most or all of the lymph nodes You will be asleep the whole time. The surgeon makes a small cut in your armpit to remove the lymph nodes. Generally, they remove between 10 and 15 lymph nodes. But the number of nodes in the armpit varies from person to person.
How many lymph nodes are there in the body?
In total, there are between 20 to 30 axillary lymph nodes, though the exact number varies between individuals. The commonest arrangement of these lymphatic pathways is a single linear chain, then a chain branching into two linear chains, and, least common, is a network configuration.[17] Tracing these lymph nodes becomes still difficult due to the high variation in the quantity of subcutaneous adipose tissue.[18] There is also physiological variation in other axillary structures such as the medial cutaneous nerve of the arm and intercostobrachial nerves.[18] Surgeons need to be aware of these when operating on the axilla to avoid iatrogenic injury.
What is the function of the axillary lymph nodes?
The function of the axillary lymph nodes, like that of the rest of the lymphatic system, is to defend against foreign particles, provide immunity against microorganisms, and return excess interstitial fluid back to the systemic circulation.[2] Lymph enters the lymph node through the afferent lymphatic vessel and subsequently flows through a system of sinuses within the node. The series of sinuses begin with the subcapsular sinus and continues to the cortical sinuses and finally, the medullary sinuses. Lymph then exits the node via the efferent lymphatic vessel.
Why do lymph nodes enlarge?
Lymph nodes can enlarge in response to numerous etiologies, including malignancy, infections, and autoimmune disease. [5] Cancer of the lymph nodes can subdivide into primary cancers such as lymphoma, as well as secondary cancers, classically of the breast. Management of these tumors may involve the surgical removal of lymph nodes and/or radiotherapy, both of which can damage the lymphatic drainage system. [25]
How many levels are there in the axilla?
Further, the area in the axilla divides into three levels based on where the lymph nodes are traceable. They are:
Where do lymph nodes get their blood?
Lymph nodes are generally found in close association with blood vessels. The axillary lymph nodes receive their blood supply from the axillary artery , and venous drainage occurs via branches of the axillary vein. Interestingly, it has been shown that stage II breast cancer and above are associated with a significant increase in the number of blood vessels in axillary lymph nodes. [12]
Where are axillary lymph nodes located?
The axillary lymph nodes reside in the axillary pad of fat and fall into five groups.[3] Every group of lymph nodes receives lymph from a specified, nearby region.
What are the three compartments of the lymph node?
Structurally a lymph node consists of three basic compartments; a cortex, paracortex, and medulla. [7] There are many types of specialized cells within the lymph node concentrated in these areas.[7] The B cell lymphocytes are classically found in the outer cortex and may form lymphoid follicles, while T cells and dendritic cells are classically present in the paracortex. The medulla contains macrophages, plasma cells, and B cells. Activation of a lymph node leads to the development of germinal centers within lymphoid follicles. These are areas in which mature B cells hypermutate, proliferate, and differentiate, to mount an immune response. [7]
Why does my lymph node hurt?
It is likely to occur when you have suffered a bacterial or viral infection. Swollen lymph node locations normally help the doctor establish the kind of infection that one could be suffering from. It is likely for the occipital node to become painful as the nearby nerves start pressing the node.
What does it mean when your lymph nodes are inflamed?
Inflamed lymph nodes in your back indicate that one has a viral or bacterial infection. But the same nodes could also be an indication of cancer. Swollen lymph nodes in your back region mean that the nodes in the upper and lower section have started to malfunction. Some of the factors that could be causing this include:
Why is my occipital node swollen?
The scalp of Head infections. A head infection is always the most obvious reason as to why your occipital nodes could be swollen. A node that is swollen will normally be tender to your touch and will feel as though it has been raised from the skin surface. Ringworms, lice, or dandruff may cause an infection.
What does it mean when you have a swollen lymph node?

How are lymph nodes linked to each other?
These nodes are linked to each other by vessels that make up your circulatory system. They tend to be a major site where white blood cells and the B and T lymphocytes can be located. This is what makes them essential to your immune system.
What causes a swollen leg?
Lupus—another inflammatory disease targeting your lungs, joints, heart, skin, blood cells, and your kidneys. Cancers that can cause this problem in your legs include: Lymphoma—this is cancer originating from your lymphatic system. Leukemia—cancer of the blood which affects your lymphatic system and your bone marrow.
Why do my ears swell up?
Infections, e.g., bacteria that may be present in your mouth and fungal infection, can lead to nodes behind your ears becoming swollen. Given that they mainly help in fighting infections that have found their way into the body, they are constantly being exposed to all kinds of pathogens. Therefore, as they start to produce antibodies to assist in fighting off the infections, they begin to swell.
Where are the paratracheal and tracheobronchial lymph nodes located?
The paratracheal and tracheobronchial groups of lymph nodes are located in the neck and also in the junction where the trachea meets the bronchi, respectively. These accept drainage from the heart, lungs, bronchi, and thoracic trachea as well as other lymph nodes.
Where are the lymph nodes located in the thorax?
Thoracic lymph nodes are separated into two types: parietal lymph nodes located in the thoracic wall, and visceral lymph nodes, which are associated with the internal organs. Due to their location, abnormalities of the lymph nodes in the thorax, or chest, are not easily detected. However, any changes in the size or amount of these lymph nodes could be indicative of several types of extrapulmonary or pulmonary diseases. For diagnostic purposes, lymph nodes of the thorax can be further divided into sub-categories. The lung lymph nodes can be found along the bronchi. The paratracheal and tracheobronchial groups of lymph nodes are located in the neck and also in the junction where the trachea meets the bronchi, respectively. These accept drainage from the heart, lungs, bronchi, and thoracic trachea as well as other lymph nodes. The posterior mediastinal group of lymph nodes, located near the thoracic aorta, is closely linked to the tracheobronchial group and primarily drains into the thoracic duct. The chest wall thoracic lymph nodes receive drainage from the breasts, arms, pectoral muscles, and other muscles and skin located in the upper section of the chest.
Where is the posterior mediastinal lymph node located?
The posterior mediastinal group of lymph nodes, located near the thoracic aorta, is closely linked to the tracheobronchial group and primarily drains into the thoracic duct.
How many nodes are there in the subscapular group?
Subscapular group: the subscapular (posterior) nodes consist of six or seven nodes that lie along the posterior axillary fold and subscapular blood vessels. These nodes receive lymph from the posterior aspect of the thoracic wall and scapular region.
What is the posterior group of lymph nodes?
Posterior group: the posterior group consists of a few nodes that lie on the posterior aspect of the crura and connects with the lateral aortic and posterior mediastinal nodes. The visceral lymph nodes drain deeper structures of the thorax and muscles attached to the ribs.
How many lymph nodes are there in the human body?
A normal young adult body contains up to 450 lymph nodes, of which 60-70 are found in the head and neck, 100 in the thorax and as many as 250 in the abdomen and pelvis.
What is the function of lymph nodes in the thorax?
They are small, oval or kidney-shaped encapsulated centres of antigen presentation and lymphocyte activation, differentiation and proliferation. They vary in size from 0.1 to 2.5 cm in length.
Why is axillary lymph node dissection performed?
Axillary lymph node dissection may be performed because the presence of metastases within axillary lymph nodes has strong prognostic significance and might influence decisions on adjuvant therapy. However, axillary lymph node dissection can lead to chronic postoperative problems such as:
What are the complications of axillary lymph nodes?
Axillary lymph node dissection may be performed because the presence of metastases within axillary lymph nodes has strong prognostic significance and might influence decisions on adjuvant therapy. However, axillary lymph node dissection can lead to chronic postoperative problems such as: 1 pain 2 seroma formation 3 reduced mobility of the arm 4 impaired sensation 5 lymphoedema

What is the lymph system?
The lymph (or lymphatic) system is a part of your body’s immune system. It includes a network of lymph vessels and lymph nodes. Lymph vessels are a lot like the veins that collect and carry blood through the body. But instead of carrying blood, these vessels carry the clear watery fluid called lymph. Lymph fluid also contains white blood cells, which help fight infections.
What is it called when a lymph node is removed?
Removal of one lymph node is considered a biopsy, but when many lymph nodes are removed, it’s called lymph node dissection . When cancer has spread to lymph nodes, there’s a higher risk that the cancer might come back after surgery. This information helps the doctor decide whether more treatment, like chemo, immunotherapy, targeted therapy or radiation, might be needed after surgery.
What is the function of lymph vessels?
Lymph vessels send lymph fluid through nodes throughout the body. Lymph nodes are small structures that work as filters for foreign substances, such as cancer cells and infections. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid.
How to tell if lymph node is cancer?
The only way to know whether there is cancer in a lymph node is to do a biopsy. Doctors may remove lymph nodes or take samples of one or more nodes using needles. The tissue that’s removed is looked at under the microscope by a pathologist (a doctor who diagnoses illness using tissue samples) to find out if there are cancer cells in it. The pathologist prepares a report, which details what was found. If a node has cancer in it, the report describes what it looks like and how much was seen.
Why do lymph nodes enlarge?
When there’s a problem, such as infection, injury, or cancer, lymph nodes in that area may swell or enlarge as they work to filter out the “bad” cells. Swollen lymph nodes (lymphadenopathy) tell you that something is not right, but other symptoms help pinpoint the problem. For instance, ear pain, fever, and enlarged lymph nodes near your ear are clues that you may have an ear infection or cold.
Where does lymph fluid filter?
Lymph fluid from the fingers, for instance, works its way toward the chest, joining fluid from the arm. This fluid may filter through lymph nodes at the elbow, or those under the arm. Fluid from the head, scalp, and face flows down through lymph nodes in the neck. Some lymph nodes are deep inside the body, such as between the lungs or around the bowel, to filter fluid in those areas.
Where are lymph nodes swollen?
Some areas where lymph nodes commonly swell are in the neck, groin, and underarms. In most cases, only one area of nodes swells at a time. When more than one area of lymph nodes is swollen it’s called generalized lymphadenopathy. Some infections (such as strep throat and chicken pox), certain medicines, immune system diseases, and cancers like lymphoma and leukemia can cause this kind of swelling. Your health care provider will look for more information to figure out the cause of the swelling. Lymph node swelling is often caused by something other than cancer.
