Awareness of breast cancer among adolescent girls in Colombo, Sri Lanka: a school based study

BACKGROUND: Breast cancer is the commonest cancer in women worldwide. Although programmes promoting breast cancer awareness are being carried out throughout Sri Lanka, few have targeted school students. We conducted this study to assess the knowledge, attitudes and practices regarding breast cancer with reference to screening, services available, breast self-examination, and sources of information, among adolescent schoolgirls in the Colombo District of Sri Lanka. METHODS: The knowledge, attitudes and practices related to breast cancer were assessed among 859 adolescent girls in schools within the Colombo District, using a self-administered questionnaire. Classes and students were selected using multi-stage stratified cluster sampling. RESULTS: Of the total sample, approximately 60% of respondents identified ‘history of breast lump’, ‘family history of breast cancer’ & ‘exposure to irradiation’ as risk factors for breast cancer. Although most were aware that the presence of a breast lump was an important warning sign, awareness of other warning signs was poor. Only 35.6% identified mammogram as an effective screening method. One third of the sample maintained that they are unaware of symptoms, diagnostics and treatment of breast cancer. Of those who were aware, 90.6% named surgery as a treatment option for breast cancer, 79.4% were unaware that chemotherapy is used. Of the total sample, 17.1% knew how to perform breast self-examination, and only 9.4% were aware of currently available breast cancer screening services. Knowledge was significantly better among students who had a relative with breast cancer. CONCLUSIONS: There were significant deficiencies in knowledge, attitudes and practices on breast cancer in the study population. In particular, knowledge on breast self examination was poor. There is a need for awareness programs aimed specifically at this important target group.
