Abstract: Objective To investigate knowledge, attitude, and practice of exercise for post-operative breast cancer. Methods 110 postoperative breast cancers were investigated using a self-designed questionnaire which included general condition of patients, knowledge, attitude and practice of exercise after breast surgery. Results The rate of effective response was 98%. The average rate of awareness about postoperative exercise for breast cancers was 87%, and the score of knowledge of intensity and forms of exercise was the lowest, while the announcements of post-operative exercise was the highest. All of the patients presented positive attitude toward exercise, however, some of them indicated that they couldn't insist on it. 41% exercised only in one form, 78% at a low intensity, 41% less than 3 times per week, and 74% at least 30 minutes per session. Only 7% did traditional Chinese medical exercise. Time after surgery correlated positively to general scores (r=0.40, P<0.01), kinds of exercise (r=0.41, P<0.05) and intensity of exercise (r=0.43, P<0.05). Phase of cancer correlated negatively to general scores (r=-0.37, P<0.05) and exercise time (r=-0.38, P<0.05). Conclusion The knowledge on intensity and form of exercise after operation is not popular in post-operative breast cancers.
