Surgery is usually the main treatment for breast cancer. Depending on the size of the cancer and whether it has spread, you may have only the cancer removed (breast-conserving surgery) or the whole breast removed (mastectomy). Other treatments include chemotherapy, radiotherapy, hormone therapy and targeted medicines.
The National Audit of Primary Breast Cancer publishes results for each NHS trust. One measure is how often women need a further operation after breast-conserving surgery, for example because some cancer cells were found at the edge of the tissue removed.

How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Volume bands. Cut points are the lower quartile, median and upper quartile of all 115 NHS trusts in the NAoPri table in the published table, rounded. So about a quarter of NHS trusts in the NAoPri table fall in each band. The exact number is shown under the band.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. This audit publishes figures for each NHS trust, which may run several hospitals. The operation may only be done at one of them.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- National figures. National figures are England (unadjusted), from the NAoPri data tables.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
