The incidence of local recurrence at five years is low among women over 55 years with early-stage breast cancer who were treated with breast-conserving surgery and endocrine therapy without radiotherapy, according to a Canadian study in The New England Journal of Medicine.

Dr Timothy Whelan, from McMaster University in Hamilton, Ontario, and colleagues performed a prospective cohort study involving women aged 55 and over who had undergone breast-conserving surgery for T1N0, grade 1 or 2, luminal A-subtype breast cancer plus adjuvant endocrine therapy.
