The efficacy of breast self-examination in helping to reduce mortality from breast cancer has not been rigorously demonstrated.
To assess efficacy, a large, randomized trial was initiated in Shanghai, China.
From October 1989 to October 1991,267040 current and retired female employees associated with 520 factories in the Shanghai Textile Industry Bureau were randomly assigned on the basis of factory to either a self-examination instruction group (133375 women) or a control group (133665 women).
The women were born within the period from 1925 through 1958.
Women in the instruction group were given intensive training in breast self-examination, including the use of silicone breast models and personalized instruction, plus two subsequent reinforcement sessions and multiple reminders to practice the technique.
Women in the control group were asked to attend training sessions on the prevention of low back pain.
All women have been followed for the development of breast diseases and for death from breast cancer.
A high level of participation during the first 4-5 years of the trial was documented among women in the instruction group.
Randomly sampled women in this group demonstrated greater proficiency in detecting lumps in breast models than did randomly sampled women in the control group. (...)
