Abstract:
Background: Breast cancer [BC] is the commonest cancer in women in Sri Lanka. This study aimed to assess the
level of knowledge on BC among sample of adults from the general public. Materials and Methods: A household
survey was conducted among a representative sample of adults of general public [n=1500] living in Colombo
district. A pretested interviewer-administered questionnaire was used to assess the knowledge on BC. Overall
knowledge and knowledge on – different aspects of BC were estimated based on percentage scores and were
presented as ‘good / poor’ levels based on predetermined cut-offs. Results: [n=1500] Response rate was 97.2%.
Mean age of participants was 37.21 [SD = ± 9.7] years and 48.3% [n = 725] of the sample were males. Only 207
[13.8%] [95% CI - 12.1 – 15.6] adults have a ‘good’ overall knowledge on breast cancer. Less than 20% had ‘good’
knowledge on risk factors, symptoms, screening / diagnosis methods and services provided through Well-Women
Clinics. Those with knowledge on available treatment methods were 31.8% [95% CI – 29.5 – 34.1]. Being female
[p<0.0001], married [p<0.0001], with high level of education [p<0.001] and being employed [p<0.0001] were
associated with a ‘good’ overall knowledge on breast cancer. Conclusion: Knowledge on risk factors, symptoms,
screening / diagnostic methods and the services provided through Well-Women Clinics were particularly poor
among adults of the general public. Educational interventions targeted at these aspects are recommended to improve
awareness among the general public on BC.
