When a person has cancer, sometimes the cancer will metastize to other areas of the body. When cancer has metastizes, the lymph nodes can become involved due to the cancer spreading through the lymphatic fluid.

Cancer spreads, or metastasizes, through the lymphatic system. This system controls the flow of certain fluids throughout the body. When cancerous cells move through the lymphatic system, they may start dividing at the new site, spreading the cancer.

a lymph node is where B and T cells of your immune system get "primed," as in they first meet their match of what molecule they should respond against to attack and remove from your body.

specifically, the B and T cells react against MHC molecules found on "non-self" molecules, whatever those may be. they get primed by dendritic cells (NOT the same thing as the dendrites on neurons). the dendritic cells endocytose (take up/eat) a microorganism (like a bacteria or a virus particle) and they take the certain molecular pattern of it that the T or B cell will respond to and attack. since they are new T and B cells in the lymph node to be primed, they don't actually attack the dendritic cell, they just recognize the molecule it's presenting and say "oh, ok, that's what i'm looking for out in the body to attack and destroy." once they've been primed they can be sent out into the body through the lymphatic vessels and circulatory system and into the tissues to potentially run into the specific molecule they are supposed to mount an attack against. this is also where, once a B cell meets it's antigen (molecule it is supposed to attack), it will multiply and differentiate into more B cells to act as "memory cells" for the next time that organism is around, and some of the new progeny cells will be come plasma cells (not the same thing as blood plasma) and will produce the actual antibodies that bind to the antigen and cause the T cells to come join the attack to continue the process of removal of whatever microorganism caused the attack.
T cells may also be multiplied here, but most B and T cell replication is done in the bone marrow. (except for mature B cell replication to produce the plasma and memory cells--this occurs in the lymph nodes.)

and the spleen is technically a lymph node, and it is where blood gets the microorganisms and dead T and B cells filtered out of it. there is very little if any priming going on in this "lymph node." mostly it just keeps the microorganisms and junk out of the blood as best it can so they don't get sent around and cause trouble or just clog up the blood with unnecessary waste.

hope this helped!

lymph nodes filter out particles from the lymph before it enters the blood and contain non-granular white blood cells that act as phagocytes

Can lymph edema spread to your upper limbs from your lower limbs?

Yes. Lymphedema can spread to unaffected area and if not treated can also become a form of cancer called, Lymphangiosarcoma. If you have Lymphedema, please see a doctor immediately.

Cancer cells break loose and spread throughout the?

Cancer cells can break loose from the primary tumor and spread to other parts of the body through a process called metastasis. During metastasis, cancer cells invade surrounding tissues, enter the bloodstream or lymphatic system, and travel to distant organs or tissues where they can form new tumors. The spread of cancer cells to distant sites is a key characteristic of advanced or metastatic cancer and is a major factor in the progression and severity of the disease. The two main routes of metastasis are: Hematogenous Metastasis (Bloodstream): Cancer cells can enter the bloodstream, allowing them to travel to distant organs and tissues through the circulatory system. Once in the bloodstream, cancer cells can be carried to various organs, and some may lodge in small blood vessels at distant sites. The ability of cancer cells to survive in the bloodstream and establish new tumors depends on several factors, including the interaction between cancer cells and the microenvironment of the target organ. Lymphatic Metastasis: Cancer cells can also spread through the lymphatic system, a network of vessels and nodes that transport lymph throughout the body. Lymph nodes act as filters, and cancer cells may accumulate in lymph nodes near the primary tumor before spreading to more distant nodes. From the lymph nodes, cancer cells can travel through the lymphatic vessels to other parts of the body. The organs or tissues where metastatic cancer cells settle and form new tumors are called metastatic sites. The choice of metastatic sites can vary depending on the type of cancer and the characteristics of the cancer cells. Common metastatic sites include the lungs, liver, bones, and brain.


The skin infection associated with melioidosis may spread to what tissue?

A localized skin infection that may spread to nearby lymph nodes.


Why metastasis does not occur in spleen and muscle?

Due to absense of lymph in spleen it is not affected by malignant cancer

What distinguishes a sentinel node from other nodes?

A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.


How can breast cancer spread to axilla?

The first station for the spread of breast cancer is the lymph nodes in the axilla then to the lymph nodes in the neck. If a patient has a biopsy it is not uncommon to have a test on the lymphnodes there.


Why are lymph nodes removed in cancer treatments?

Removal of Lymph NodesThe lymph nodes are a way of travel for breast cancer cells. This is the first place they go if the cancer has spread. They remove the lymph nodes to see if the cancer has spread. Hopefully, the breast cancer cells will not have gone past the lymph nodes, and with removal of them and the cancer in the breast, the cancer is gone. Unfortunately, this is not always the case, and the cancer can spread to other parts of the body through the lymph nodes. The more lymph nodes that are positive for cancer, the more likely the cancer has spread to distant places in the body. Early detection is the key! Keep up on the mammograms and self examination. It could save your life!AnswerThe above poster gave an excellent answer, but just wanted to add that lymph nodes are throughout our body and are filters for our body, thus, of there are cancer cells they can travel through lymph nodes.


What can you tell me about stage 3 lung cancer?

Diaphragm cancer, or any cancer that is classified as stage 3 means it has spread to the lymph nodes. The lymph nodes accelerate the spread of the disease.


What can a mediastinoscopy show about the lymph nodes of a lung cancer patient?

The lymph nodes in the mediastinum are likely to show if lung cancer has spread beyond the lungs.


What does nodal status mean in relation to breast cancer?

The American Joint Committee on Cancer (AJCC) TNM system is a staging system that classifies cancers based on their T, N, and M stages, which is to say their Tumor, Node and metastasis. The nodal status refers to the "N" portion of this classification system. The N indicates the presence, if any, of cancer spread to other lymph nodes. The system is: NX: Regional lymph nodes cannot be assessed. N0: Cancer has not spread to regional lymph nodes. N1: Cancer has spread to 1 to 3 lymph node(s) under the arm N2: Cancer has spread to 4 to 9 lymph nodes under the arm N3: Cancer has spread to 10 or more lymph nodes under the arm or also involves lymph nodes in other areas around the breast. The TNM, taken together, yield the stage of breast cancer a patient is in.
