Lymphoedema means swelling caused when lymph leaks into the tissues. Lymph is a colourless fluid that circulates through the body in a network of vessels similar to blood vessels. It’s part of the immune system and also carries waste products and anything that could be harmful away from the tissues. The lymph drains into the bloodstream and anything that the body doesn’t need is removed and passes out in the urine.

As well as the vessels that carry the lymph around the body, the lymphatic system also contains lymph nodes (also known as ‘glands’). Lymph nodes filter the lymph fluid and also contain white blood cells (lymphocytes) which destroy bacteria and viruses.

Sometimes cancer cells move into the lymph nodes. If your lymph nodes are found to contain cancer cells, you may be advised to have the affected nodes removed. In some cases it’s necessary have all the lymph nodes in the area removed. This is to stop the cancer cells travelling through the lymphatic system.

Loss of the lymph nodes makes it more difficult for the lymph to circulate, so it can pool within the vessels and leak into the surrounding tissues. This causes the tissues to swell (lymphoedema) and feel heavy, tight, full or stiff. If you press a fingertip into the swollen area, it leaves an impression. Sometimes the fluid leaks through the surface of the skin.

Depending on the type of cancer you have and where the affected lymph nodes are, lymphoedema can occur in various different parts of the body. In ovarian cancer, the affected lymph nodes tend to be in the groin, so lymphoedema develops in the leg.

Lymphoedema can’t be cured, but it can be managed with the help of a specialist to reduce its effects on your health and lifestyle. If you’re experiencing swelling, changes in sensation or skin changes such as stretching, thickening, dryness, or scaliness, seek advice from a healthcare professional who can confirm whether your symptoms are caused by lymphoedema.

In October 2020, we held a live webinar with Lymphoedema Support Network about why lymphoedema can occur in people with ovarian cancer and how this can be managed, which you can watch here:


If lymphoedema is suspected, you will be referred to a specialist in lymphoedema, such as a lymphoedema nurse, doctor, physiotherapist or occupational therapist. Therapies for lymphoedema may be available on the NHS, but this varies depending on where you live.
