Age-specific patterns of breast cancer in Nigerian women unraveled through histological analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sub-Saharan African women face a high burden of breast cancer, influenced by genetic and lifestyle factors. However, the lack of comprehensive, age-stratified data hinders the identification of risk factors and the development of effective, population-specific interventions. This study aimed to assess age-related variations in breast cancer prevalence among Nigerian women, providing insight into associated risk factors and disease trends. A retrospective review of 3,263 breast histopathology records (9.46% of total from 2015 to 2023) was conducted. Lesions-benign and malignant-were analyzed across five age groups: children and adolescents (0-19), young adults (20-39), middle-aged (40-59), higher-aged (60-79), and elderly (≥ 80), using MS Excel and GraphPad Prism 8.0. Statistical comparisons were performed by age and lesion type. Most cases were in young adults (45.97%) and middle-aged women (33.83%). The left breast was more commonly affected (46.86%) and had higher malignancy rates than the right (44.41%) or bilateral lesions (7.20%). Benign lesions were predominant (56.76%), especially among young adults (57.34%). Malignancy incidence increased with age, peaking in middle-aged women (53.30%). Fibroadenoma was the most frequent benign lesion in children and adolescents and young adults, while fibrosis predominated in middle age. Invasive ductal carcinoma (IDC) was the leading malignant subtype, with a sharp rise by 2023-particularly among middle-aged (172 cases) and young adult women (71 cases). Among 339 immunohistochemically profiled cases, triple-negative breast cancer (TNBC; 42.77%) and ER+/PR+ tumors (36.87%) were most common. TNBC was the only subtype detected in children and adolescents. Middle-aged women bore the highest burden of all subtypes, with a marked increase in TNBC and ER+/PR+ cases in 2023. The rising incidence of aggressive subtypes, particularly TNBC, highlights the need for enhanced molecular diagnostics and personalized therapies. Age-specific trends reinforce the urgency for targeted screening, especially for young and middle-aged Nigerian women.
