The Effect of Breast Self‐examination on Early Detection and Survival
To investigate the effect of breast self‐examination (BSE), we compared the stages, survival, and the risk of death for 355 patients with breast cancer detected by BSE with those for 1,327 patients with breast cancer detected by chance. The early stages of the disease were found to be more common am...

| description | To investigate the effect of breast self‐examination (BSE), we compared the stages, survival, and the risk of death for 355 patients with breast cancer detected by BSE with those for 1,327 patients with breast cancer detected by chance. The early stages of the disease were found to be more common among the symptomatic breast cancer patients detected by BSE than those by chance. The 5‐year overall survival rate was 94.4% for the symptomatic patients detected by BSE, and was significantly higher by 8.7% than that (85.7%) for patients detected by chance (P< 0.001). The 10‐year survival rate was 81.6% for patients detected by BSE, and 76.6% for cases detected by chance (the difference was not significant).
