Lymphedema

Lymphedema is swelling in the affected arm, hand or chest wall caused by a buildup of lymph fluid. The swelling happens because lymph nodes, which normally act as filters, aren’t able to do their job as well because they’ve been removed by surgery, or they’ve been damaged by radiation therapy or the cancer itself. Lymphedema is different from the swelling in the breast, armpit and arm areas that can happen just after surgery.

Lymphedema can happen soon after treatment, months or even years later. It can be a temporary or a long-term condition. It’s easier to manage if you get help for it early.

Watching for signs of lymphedema

The start of lymphedema can be hard to notice, but it’s very important to treat it quickly. Tell your doctor right away if you notice swelling in your hand, arm or chest wall – even if it happens years after treatment. Some other signs to watch for are:

feeling of fullness, puffiness or heaviness in the arm
decreased flexibility of movement in your hand, wrist or arm
jewellery (including watches) feeling tight even though your weight hasn’t changed
problems fitting your arm into your sleeves
redness or increased warmth, which may mean that you have an infection
