  schema:description "Radiotherapy after breast-conserving surgery halves the chance of the cancer coming back and prevents about one death in breast cancer for every four recurrences it prevents. In older women with small, hormone-sensitive, slow-growing tumours who will take endocrine therapy, the recurrence risk is so low to start with that leaving radiotherapy out changes almost nothing."@en ;
