This leaflet has been written to help you to understand more about how to check your lymph nodes yourself. It tells you why you should be doing it, what lymph nodes should be checked, how often they should be checked and how to check them, and where you can find out more about this issue. Lymph nodes are part of the lymphatic system, which is a network of tiny tubes that carry a colourless fluid called lymph through the skin and deeper parts of the body. Lymph fluid contains immune cells lymphocytes nutrients and waste materials. The lymph nodes filter out harmful organisms and abnormal cells before the lymph reaches the blood stream.
Our bodies have a network of lymph vessels and lymph nodes. Lymph is pronounced limf. It collects fluid, waste material, and other things like viruses and bacteria that are in the body tissues, outside the bloodstream. 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.
It can be alarming to find a new bump anywhere on your body. It could be anything from an ingrown hair to a swollen lymph node. Sebaceous cysts are a common type of cyst that forms in blocked or damaged sebaceous glands. These glands secrete sebum, which is an oily substance that lubricates your skin and hair. Sebaceous cysts feel like small, soft bumps.
