The lymphatic system and bladder cancer

The lymphatic system helps protect us from infection and disease. It is part of the body’s immune system.

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 bladder cancer cells spread outside the bladder, they can go to the lymph nodes near the bladder. These are called pelvic lymph nodes.
