II. Efficacy
- Study of 266,000 women in Shanghai, China
- Intervention: Intensive self exam instruction
- Control Group: Low Back Pain prevention instruction
- Results
- No difference in Breast Cancers identified
- Twice as many benign growths found in BSE group
- Interpretation
- Insufficient evidence to recommend for or against
- References
- Meta-analysis findings consistent with Shanghai study
- SBE with no significant impact on mortality
- Increases the number of biopsies performed

III. Precautions
- Self Breast Exam is no longer routinely recommended due to low efficacy (see above)
- Does not lead to decreased Breast Cancer mortality
- High risk of False Positives
- Consider a Breast self-awareness protocol as an alternative
- Women 20 years and older recognize normal appearance and feel of their Breasts (without systematic self-exam)
- Women who find new Breast changes should seek prompt medical attention
