Local control and survival in breast cancer patients stage I and II after Breast Conserving Treatment (BCT); comparison of two groups

Purpose: To present 5 years local control and survival in patients treated 1998–99. To establish eventual prognostic factors for this group. To compare these results with a group of patients treated before 1990.
