Lymph Nodes and Cancer What is the lymph system? 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 carries oxygen and other nutrients to the cells, and carries away waste products like carbon dioxide CO2 that flow out of the cells.

Lymph fluid also contains white blood cells, which help fight infections. Lymph fluid would build up and cause swelling if it were not drained in some way.

Lymph vessels draw up the lymph fluid from around the cells to send it towards the chest. There, lymph fluid collects into a large vessel that drains into a blood vessel near the heart. Lymph nodes and what they do Lymph vessels route lymph fluid through nodes throughout the body.

Lymph nodes are small structures that work as filters for harmful substances. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid.

There are hundreds of lymph nodes throughout the body. Each lymph node filters the fluid and substances picked up by the vessels that lead to it. 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. The lymph fluid slowly flows in from all around the body, making its way back to the chest.

At the end of its journey, the filtered fluid, salts, and proteins are dumped back into the bloodstream. Swollen lymph nodes 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.

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.

Cancer can spread from where it started the primary site to other parts of the body. When cancer cells break away from a tumor, they can travel to other areas of the body through either the bloodstream or the lymph system.

Cancer cells can travel through the bloodstream to reach distant organs. If they travel through the lymph system, the cancer cells may end up in lymph nodes.Swollen lymph nodes are often the earliest sign of metastatic spread of cancer cells. Now cancer researchers and immunologists at Sweden's Karolinska Institutet have discovered how cancer cells can infiltrate the lymphatic system by 'disguising' themselves as immune cells (white blood cells).

Some people worry that massage can spread cancer cells throughout the body via the lymphatic system. The lymphatic system is a network of vessels, organs and nodes through which lymphatic fluid (lymph) flows.
