Persistent adverse effects of cancer treatments on mental health, fatigue, and sleep disturbances in breast cancer survivors.
Article in BMC women's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBreast cancer is the most diagnosed cancer worldwide, affecting one in four women diagnosed with cancer. Cancer treatments, particularly chemotherapy, can adversely impact mental health, contributing to increased stress, anxiety, depression, fatigue, and poor sleep quality. This study investigated the long-term psychological effects of cancer treatment among breast cancer survivors and explored interactions between these factors.
methodsWe recruited Canadian women aged 30 to 65 with a history of breast cancer who were at least 6-months post-treatment (n = 49) and age-matched control participants (n = 44). Participants provided demographic and health information and completed online questionnaires assessing stress, depression, trait and state anxiety, fatigue, sleep quality, and physical activity.
resultsBreast cancer survivors reported significantly higher levels of stress (p = .004), depression (p < .001), state anxiety (p = .003), trait anxiety (p = .02), fatigue (p < .001), as well as poorer sleep quality (p < .001) compared to non-cancer controls. Physical activity levels and leisure-time exercise did not differ between groups (p = .13 and p = .17, respectively). While physical activity was not significantly correlated with mental health factors in either group (p’s > 0.05), most mental health factors were correlated with each other in both groups (p’s < 0.05).
conclusionOur findings enhance understanding of the long-term mental health effects of cancer treatment in breast cancer survivors, providing strong evidence that breast cancer survivors continue to experience significant psychological challenges – including stress, anxiety, depression, fatigue, and sleep disturbances. Given these persistent challenges, it is critical to incorporate comprehensive mental health assessments into cancer survivorship plans to identify psychological concerns and inform treatment strategies that address the interconnectedness of these issues.
