Swelling in the breast from your surgery and radiotherapy may happen for many different reasons. Pain and discomfort are common and swelling can happen after radiotherapy treatment. Although, these side effects would usually settle in the weeks and months after treatment has finished.
Lymphoedema can also develop after treatment with symptoms including swelling in the breast or chest wall on the side of the body where you had your surgery or radiotherapy. However, it is not possible for us to say what may be causing this change. , As your symptoms are new, we would encourage you to contact your breast care nurse, treatment team or GP to get it checked out.
