Breast loss causes negative influence on women physically, psychologically and socially. Breast prosthesis can improve patient's figure externally, increase self-confidence, thus improving quality of life. The objective was to understand the knowledge regarding breast prostheses in breast cancer patients, evaluate the quality of life of patients wearing different types of breast prostheses and to compare the physical and psychological effects of different temperature-controlled breast prostheses on patients. The investigators designed a randomized control study in one cancer center in Shanghai. In the first 6 weeks of the study, self-adhesive breast prostheses and conventional breast prostheses were used in the intervention and control group, respectively. In the later 6 weeks, the breast prostheses used were switched into another kind. Several dimensional parameters were examined by different questionnaires at the end of both 6th and 12th week including scars and skin, survey of breast prosthesis knowledge, survey assessing the comfort and practicality of breast prostheses, quality of life instruments for cancer patients and body image scale. The investigators expected that women would be satisfied with the temperature-controlled breast prosthesis and were more willing to choose self-adhesive breast prostheses.

Breast loss causes negative influence on women physically, psychologically and socially. Breast prosthesis can improve patient's figure externally, increase self-confidence, thus improving quality of life. Prospective study of different breast prostheses has not yet been performed in China. The objective was to understand the knowledge regarding breast prostheses in breast cancer patients, evaluate the quality of life of patients wearing different types of breast prostheses and to compare the physical and psychological effects of different temperature-controlled breast prostheses on patients. The investigators designed a randomized control study in one cancer center in Shanghai. Eligible participants were randomized into either intervention or control group. In the first 6 weeks of the study, self-adhesive breast prostheses and conventional breast prostheses were used in the intervention and control group, respectively. In the later 6 weeks, the breast prostheses used were switched into another kind. Several dimensional parameters were examined by different questionnaires at the end of both 6th and 12th week including scars and skin, survey of breast prosthesis knowledge, survey assessing the comfort and practicality of breast prostheses, quality of life instruments for cancer patients and body image scale.
