Why radiation if margins are clear?
Clear margins offer the lowest risk of recurrence in the same breast; wider clear margins don’t reduce this risk any further. Treatments after surgery (called adjuvant treatments by doctors), such as hormonal therapy, radiation therapy, and chemotherapy, reduce the risk of recurrence in the same breast.
