BackgroundBreast cancer accounts for 25% of diagnosed cancers and 20% of cancer-related mortality amongst women in sub-Saharan Africa. 1 Data from the International Agency for Research on Cancer suggest about 100 000 breast cancer cases are diagnosed annually in the African region, with the largest number of country-specific cases diagnosed in Nigeria (circa 14 000) yearly. 2 While the breast cancer incidence and mortality rates remain highest in fully industrialised nations, rates are rapidly increasing in developing countries. Thus, there is a dire need to detect cancer early, when it is more responsive to treatment. 3 Mammography is a breast imaging method that employs low-dose x-rays to detect cancer early, thereby reducing the incidence of advanced cancers with poor prognosis. 3 Mammography screening in Nigeria is offered to women aged from 40 to 70 years, 4 although women under 40 years may also be invited for mammograms if they have a strong family history of breast cancer. 5 The efficacy of mammography in younger women is debatable (because of higher breast density). 6 Nevertheless, missing a mammogram can significantly increase the likelihood of being diagnosed with cancer at a later stage. 7Background: Breast cancer accounts for 25% of diagnosed cancers and 20% of cancer-related mortality in women from sub-Saharan Africa. Given the early onset of breast cancer in African women, there is a need to better understand how age-related risk factors contribute to mammography uptake in this population.
