Methods Through the "Rukang Cloud" breast cancer rehabilitation club platform, a web-based WeChat survey was conducted among 119 postoperative breast cancer patients who underwent modified radical mastectomy from May 2012 to May 2020. The survey investigated their awareness of breast prostheses and analyzed the results. Results 79.83% of breast cancer patients were aware of the existence of breast prostheses, and 52.10% had access to them. 80.00% of the patients believed that a breast prosthesis could improve physical appearance by compensating for the loss of body part; 61.05% thought it could maintain body balance; 47.37% believed it could also protect the chest area. More than half (52.10%) of the patients expressed a need to wear a breast prosthesis, with the acceptable price range mainly between 200 and 500 yuan.
