Introduction Breast cancer is the most prevalent cancer and the second leading cause of cancer-related deaths among women in low and middle-income countries (LMICs), including sub-Saharan Africa. Mammography screening is the most effective screening method for the early detection of breast cancers in asymptomatic individuals and the only screening test that decreases the risk of breast cancer mortality. Despite the perceived benefits, it has a low utilisation rate in comparison with breast self-examination and clinical breast examination. Several interventions to increase the uptake of mammography have been assessed as well as systematic reviews on mammography uptake. Nonetheless, none of the published systematic reviews focused on women living in LMICs. The review aims to identify interventions that increase mammography screening uptake among women living in LMICs. Methods and analysis Relevant electronic databases will be systematically searched from 1 January 1990 to 30 June 2021 for published and grey literature, including citation and reference list tracking, on studies focusing on interventions to increase mammography screening uptake carried out in LMICs and written in the English language. The search will incorporate the key terms: mammography, interventions, low- and middle-income countries and their associated synonyms. Randomised controlled trials, observational studies and qualitative and mixed methods studies of interventions (carried out with and without comparison groups) reporting interventions to increase mammography screening uptake in LMICs will be identified, data extracted and assessed for methodological quality by two independent reviewers with disagreements to be resolved by consensus or by a third author. We will use narrative synthesis and/or meta-analysis depending on the characteristics of the data. Ethics and dissemination Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.
