Breast reconstruction with an expander prosthesis following mastectomy does not cause additional persistent pain: A nationwide cross-sectional study

reconstruction. Results: A total of 129 patients treated with mastectomy and breast reconstruction with a sub- pectoral implant were compared with 1131 patients treated with mastectomy without recon- struction. Prevalence of persistent pain for patients treated with mastectomy followed by reconstruction with an implant was 40% compared to 48% of patients treated only with mastec- tomy. We found no increased risk of persistent pain in patients having a reconstruction with an implant compared with mastectomy without reconstruction (odds ratio (OR) 0.82, 95% confi- dence interval (CI) 0.55e1.22, P Z 0.33) when adjusting for age, axillary procedure,
