Objectives: To describe female workers’ knowledge and practice on breast cancer prevention and early detection at the 10th Garment Joint Stock Company in 2017. Method: Cross-sectional description of 259 female workers. Results: 23.9% knew about factors that increased the risk of breast cancer, 21.6% knew that there was no vaccine to prevent cancer, 11.6% knew the age that was susceptible to cancer and only 22.8% of female workers had good knowledge of cancer prevention. The rate of having never heard of breast self-examination method was 56.8%, mammography was 65.3%, the rate of having knowledge about breast self-examination method was only 19.7%, the time of performing breast self-examination was 28.2% and and the rate of knowledge of early signs of breast cancer was only 13.9%. The percentage of female workers with good practice on prevention and early detection of breast cancer was 79.9%, 100% of female workers did not smoke or drink alcohol, 53.3% of them consumed enough green vegetables as recommended; and 40.9% of them have a low-fat diet. The rate of self-assessment as a good practice for early breast cancer detection methods was very low: breast self-examination (11.2%), breast examination at specialized health facilities (22.8%), and mammography (8.1%). Conclusions: There is a disparity in knowledge and practice of breast cancer prevention and early detection among 259 female workers. The percentage of workers with correct knowledge about breast cancer prevention and methods of early detection of breast cancer was low, the percentage of female workers had good practice on prevention and early detection of cancer was quite high, but the rate of good practice when self-assessing practices of early detection methods was very low. Breast self-examination was less accurate and however, regular self-examination would detect breast abnormalities early, increase the chances of treatment, and prolong the patient's life.
