The study examined the pattern of and factors associated with use of alternative medicine (AM) among Chinese breast cancer patients. An analytical, cross-sectional survey of 352 breast cancer patients from two breast cancer centers was conducted in 1997. Amongst the respondents, the usage rate of alternative medicine was 27.8%. Factors forming the use of AM included being young to middle-aged, having higher education and a belief that AM would enhance orthodox treatment. A substantial proportion of Chinese breast cancer patients use AM besides conventional medicine. There is a need to integrate AM with conventional medicine to improve the service provision for cancer patients.
