ObjectiveTo compare the clinical value of breast conserving surgery and modified radical mastectomy in early breast cancer patients. MethodsA selection of 130 early breast cancer patients admitted to Qingdao Women? and Children's Hospital（Chengyang District）from January 2017 to December 2019 were divided into observation group and control group，with 65 cases in each according to the random number table method. The observation group was treated with breast-conserving surgery，the control group was treated with modified radical mastectomy. The intraoperative conditions，treatment effects，complications and symptom improvement of the two groups were compared. ResultsThe intraoperative blood loss in the observation group（37.52±8.41）mL was significantly lower? than that in the control group（64.25±10.32）mL，the difference was statistically significant（t=16.188，P ＜ 0.05）. The operation time and hospitalization time of the observation group were（52.31±11.02）min and（10.26±1.54）d， respectively，shorter than those of the control group（87.52±14.42）min and（16.95±1.85）d，（t=15.641，22.407，P ＜ 0.05）. The total effective rate of 96.92% in observation group was significantly higher than that of 78.46% in control group （χ2 =9.630，P ＜ 0.05），the complication rate of observation group was 6.15% significantly lower than that of control group 18.46%，（χ2 =4.561，P ＜ 0.05）. After treatment，the scores of survival indexes in the observation group were better than those in the control group（P ＜ 0.05）. ConclusionCompared with modified radical mastectomy，the use? of breast-conserving surgery for early breast cancer patients can reduce intraoperative blood loss，shorten operation time and hospital stay，improve treatment effect，reduce the incidence of complications，and significantly improve and relieve the clinical conditions of patients symptoms，with high therapeutic effectiveness and safety.
