Study population
The target population comprised residents from Sungai Segamat and Jabi who completed the health survey in 2018, were recorded in the SEACO database and, previously, gave consent to be contacted about participating in research studies. Thus, we contacted women aged 40–74 years who had registered their phone number with SEACO. Only women who had a mobile phone number via which they could be contacted were able to participate in the study. BC patients and survivors, and women who reported to the research team at the time of the interview that they were experiencing BC symptoms were excluded from the research and encouraged to seek help from their local doctor as soon as possible.
