How long can you live with lymph node cancer?
Depending on the type, lymphoma can be NON life threatening. The above poster is correct. If you or someone you love has this, then search the web and go onto: www.google.com and ask your question. Print out any good information then sit and study it, making notes that you can shorten into questions later so you can ask your doctor to fill you in. Doctors are very busy in the U.S. and Canada and don't always have the time to sit down with a patient and go over every little thing and this is where the Internet is a complete God-send. My doctor's office actually has a notice encouraging his patients to write down any questions they may have. Also many pharmacists are quite qualified to answer some questions other than filling prescriptions.
Most normal axillary lymph nodes are less than 2cm in size and have a kidney -shape apperance. Lymph drainage from the breast is significant because it is by this route that a malignant disease may leave the breast.
What problems can go wrong with the immune system?
There are many diseases that involve some aspect of the immune system function or malfunction. The most obvious would be infectious diseases such as bacterial, viral and parasitic infections.
Hormones affect the immune system, so diseases that disrupt normal hormonal activity can affect the immune system.
Diseases that affect the sleep cycles also can affect the immune system since sleep deprivation has negative impacts on the immune system (e.g., sleep apnea, insomnia, etc.).
Other diseases or disorders of the immune system can manifest with over-activity and some with under-activity of the immune function, some are congenital and some are acquired, some are due to diseases that are damaging to parts of the immune system itself (e.g., alcoholism, obesity, drug use, malnutrition such as Vitamin D deficiency, etc.), and some diseases are affected by the immune system function or malfunction.
The immune system function can also be modified and affected by the treatment and medication used for some diseases and conditions, such as anti-rejection drugs used in transplants and in autoimmune diseases and anti-neoplastic chemotherapy (cancer treatment) drugs. Another that can damage the immune system function is radiation therapy.
Some examples of immune system diseases and disorders are: HIV/AIDS, systemic Lupus (SLE or systemic lupus erythematosis), and other autoimmune disorders, leukemia, lymphoma and other cancers, mononucleosis, Type 1 diabetes mellitus, allergies, asthma, Crohn's Disease, MS, Guillan-Barre syndrome. See the Related Link below for more. HIV/Aids.
How does the immune system help maintain homeostasis?
SERIOUSLY? if someone else got quest wrong, just erase it not make fun of them. ANYWAY the correct answer is:
it lets you know what's wrong with your body. It preforms certain operations to keep the body balanced out. It brings excess fluid to the bloodstream.
i hope that helped ^_^
oh and i looked up another answer and somone else got :
"Immune system in our body is such a vast subject running in volumes on which continuous research is going on…..
However it can be interestingly briefed as below:
1. Natural immunity : This is the immunity of the mother transmitted to the newborn in the uterus through placenta until its birth, and through the breast milk feeding after birth.
2. Acquired immunity : As the child after birth while growing into a man he will be acquiring some immunity or other for each and every disease/organism he is exposed, thus helping in the cure of the disease (with the help of the WBC circulating in our blood), and in developing resistance to prevent the same disease to attack second time.
3. Auto immunity : Here the body develops immunity to its own cells , tissues, organs etc. and starts rejecting them (Abnormal or let us call suicidal)!
4. immuno (gamma) globulins play a major role in developing the immune mechanism in our body. They act like military forces in protecting our body in preventing disease causing organisms to enter our body by forming similar structures like the organisms and stand before the targeted tissue (receptors), there by giving no scope to the organism to invade the tissue to cause the disease. Thus depending on the strength of these immuno globulins the disease is either made not to reoccur at all and driven away or aborted ; or made to affect with low intensity etc., when the White Blood Cells (WBC) circulating in our blood go and engulf and destroy the external organisms that have entered our body!
In this way there is a constant harmony maintained between the Body tissues, its immediate immune response and the White Blood Corpuscles (WBC) in protecting our body from invasion by external bacteria and viruses that are causing the disease and thus maintain a Homeostasis!
It is this lack of the Acquired Immune system that is responsible to cause AIDS (Acquired Immuno Deficiency Syndrome), where due to the total lack of this immune mechanism, the external organisms always gain an upper hand causing extensive uncontrollable disease there by resulting in death of the individual !"
What is the largest blood leukocyte?
That would be the macrophage the last stage of the Agranulocyte (without granules) Monocyte. A component of the reticuloendothelial system in humans, phagocytes are defensive cells that "eat" contaminants/invaders, working by envelopment and bioloigcal assault.
•Lymph nodes are masses of lymphatic tissue surrounded by a fibrous connective tissue capsule.
•The function of lymph node is to produce lymphocytes and to filter and trap substances from inflammatory and cancerous lesions.
•Special cells, called macrophages are located in lymph nodes which can phagocytose foreign substances.
•When bacteria are present in the lymph nodes, they become swollen with collections of cells and their engulfed debris and become tender.
What is a lymphatic system doctor called?
What is a lymphatic system doctor called?
The doctor for the lymphatic system is called an immunologist.
The lymphatic system is included in the study of immunology and the key primary organs of the immune system are the bone marrow and thymus, secondary are the lymphatic tissues such as the lymph nodes, lymph vessels, spleen, adenoids, tonsils and skin.
What takes place as food goes through the digestive system?
What happens is after you have chewed up all your food it will go down your gullet to your stomach where the food is broken down physically and has acids adds to it. Past your pancreas some of the food will go into one of your intestines (we have two) then into your blood as the rest will go to your other intestine and then down the toilet.
Are lymph capillaries found in the epidermis?
Yes, there are many lymph capillaries in the bottom portion of the dermis. They are there take all the waste material and recycle them!
What is the function of the dartos and cremaster muscles?
It's the muscle that surrounds the testicles and spermatic cord. It twitches involuntarily when the cremasteric reflex is stimulated, or to raise the testicles closer to the body when it's cold or the man is sexually excited. It can also be twitched voluntarily in most men using Kegels, where the muscles that tighten the anus, and stop the flow of urine, are contracted. Some men can also contract it by contracting their abdominal muscles.
What is the Survival rate for Lymph Node Caner?
A lymph node can be described as an oval-shaped organ of the in the immune sysytem, They act as filters or traps for foreign particles and are important in the proper functioning of the immune system. The same way any filter works, they trap the bad stuff so the good can flow through.
When does the immune system become active?
when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn when your imune system is dawn
Generally speaking, you will be better equipped to fight off a viral infection if you have a strong immune system, but the only thing that will give you full protection is to have immunity developed from having had the same type of flu before, or from taking a vaccination against that specific flu strain.
An added aid for your body to use to help protect you from swine flu, would be use of the anti-viral medications that are being prescribed to help fight the influenza viruses, such as Tamiflu and Relenza.
(See information in the related questions below about how your body fights swine flu and about A-H1N1/09 Vaccines and other treatments for the Novel H1N1 Swine Flu.)
It's a lymph node that drains an inflamed area. The source of the inflammation can be bacterial-viral infection, immunological disease, or malignancy.
What do you do if you have swollen lymph nodes?
A doctor can prescribe an antibiotic if the lymph node gland gets very large or painful. Under normal conditions, no care is needed because they take care of themselves. You have 8 that I can think of. Two on the sides of your neck, one under each armpit, one near the inside of each arm at the elbow and one on each leg near the femur / pelvis joint. Lymph nodes collect poisions or harmful bacteria laden white blood cells and allow them to pass into the body at a rate that the body can deal with them.
What are relationship between blood vascular system and lymphatic system?
Lymph functions
A lymph function is a defence that removes bacteria and foreign materials preventing infection and helps remove excess fluids.
A lymph vessel is something that has valves along its length to prevent backflow of the fluid being carried to the nodes.
Lymph nodes
Lymphatic nodes can clean lymphatic fluid by filtering toxins. Produce lymphocytes, antibodies and antitoxins to fight infection and ingest pathogens.
The following explains how the lymph interacts with the blood in the circulatory system
ž Plasma in blood seeps through capillary walls.
ž Plasma becomes tissue fluid and produces cells with nutrients and oxygen.
ž Excess tissue fluids with waste passes into the lymphatic capillaries.
ž Tissue fluids becomes lymph
ž Clean lymph fluids pour into the subclavian veins to become part of the blood
Why is the skin a good defense mechanism for the immune system?
It acts like a shield, so micro organisms aren't able to pass through unless there is damage to the skin. (e.g. A cut.)
Which type of leukocyte contains heparin and anticoagulant?
Basophil is the type of leukocyte that contains heparin and is an anticoagulant. The type of leukocytes that become macrophages in the tissues are monocytes.
The seven types of leukocytes are: neutrophils, eosinophils, basophils, monocytes, macrophages, dendritic cells, and lymphocytes. Neutrophils, basophils, esinophils, monocytes and lymphocytes are the five most commonly thought of.
