What are the three basic functions of a lymph node?
The lymphatic system has three functions:
- The removal of excess fluids from body tissues.
- Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.
- Production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells).
Where are lymph nodes located and what are their functions?
Lymph nodes are small, bean-shaped glands that are located along the lymphatic system (a system of vessels similar to arteries and veins through which lymph fluid travels).

The most important function of the lymph nodes is that they serve as multiplication sites for lymphocytes; phagocytic cells within them remove bacteria, viruses, and the like from the lymph stream before it is returned to the blood.
What are the two functions of the lymph nodes?
The nodes filter out the damaged cells and cancer cells. These lymph nodes also produce and store lymphocytes and other immune system cells that attack and destroy bacteria and other harmful substances in the fluid. You have about 600 lymph nodes scattered throughout your body

How common is lymphedema after lymph node removal?
A recent meta-analysis reports the incidence of breast cancer–related lymphedema to range from 0 to 3% after lumpectomy alone to as high as 65% to 70% after modified radical mastectomy (removal of breast and axillary lymph nodes) with regional nodal radiation
How do I get rid of lymphedema in my legs?
Lymphedema treatments include:
- Exercises. Light exercises in which you move your affected limb may encourage lymph fluid drainage and help prepare you for everyday tasks, such as carrying groceries.
- Wrapping your arm or leg.
- Pneumatic compression.
- Compression garments.
- Complete decongestive therapy (CDT).
Does coffee affect lymphedema?
Those with lymphedema should be wary of beverages that contain alcohol and caffeine, both of which can contribute to dehydration. For this reason, coffee and lymphedema do not mix well. Although drinking enough water is essential for those with lymphedema, diuretics — also known as water pills — should be avoided.
