The lymphatic system helps to protect us from infection and disease. Sometimes cancer can spread through the lymphatic system.
The lymphatic system helps to protect us from infection and disease. It also drains lymph fluid from the tissues of the body before returning it to the blood. The lymphatic system is made up of fine tubes called lymphatic vessels that connect to groups of lymph nodes throughout the body.
Lymph nodes (sometimes called lymph glands) are small and bean shaped. They filter bacteria (germs) and disease from the lymph fluid. When you have an infection lymph nodes often swell as they fight the infection.
Sometimes, cancer can spread through the lymphatic system. If cervical cancer spreads in this way, it is most likely to affect the lymph nodes in or above the pelvis.
