When is lymphoedema therapy recommended for breast cancer?

Breast cancer surgery or radiotherapy can affect lymph drainage around the breast, chest wall, shoulder or arm. Possible changes include swelling, tightness, heaviness, aching, skin changes or reduced movement. Some people notice symptoms gradually, while others recognise a change soon after treatment. A trained clinician can examine the area, compare sides and distinguish lymphoedema from infection, a blood clot or another cause.

Tell your breast cancer team about any new swelling, jewellery or clothing that feels tighter, or difficulty moving the shoulder. Assessment is more useful when symptoms are described clearly, including when they began and whether they change during the day. Therapy may include tailored exercises, skin care, education, movement advice and compression when appropriate. Do not start compression or intensive massage without professional guidance, especially if the skin is sore or inflamed.

Seek prompt medical advice for rapidly increasing swelling, redness, warmth, fever, marked pain, sudden breathlessness or chest pain. These features may indicate infection or another urgent problem rather than lymphoedema alone. A new change after cancer treatment deserves review even when it is mild, because early assessment can clarify the cause and protect function.

Could this swelling be lymphoedema or another condition? Should I see a lymphoedema specialist? Which exercises and skin-care steps suit my treatment history? Would compression be appropriate, and what changes should make me contact the team?
