Background The COVID-19 pandemic has significantly impacted cancer care services in the United Kingdom (UK), potentially exacerbating pre-existing health inequalities. While emerging studies have documented service disruptions, a comprehensive synthesis of how these disruptions have widened disparities remains absent. This systematic review examines the extent to which the pandemic disrupted the cancer care pathway and intensified existing disparities across the UK, identifying key sociodemographic and geographical factors influencing access to services. Methods A systematic search of PubMed, Scopus, and CINAHL was conducted for studies published between January 2020 and October 2024. Eligible studies included observational and empirical research examining disparities in cancer screening, diagnosis, treatment, and outcomes during the COVID-19 pandemic, as well as the corresponding mitigation strategies. Data extraction followed a structured approach using a custom-developed extraction form designed for this review. Study quality was appraised using a bespoke scoring system, classifying studies as high, moderate, or low importance. Narrative synthesis, following the framework outlined by Popay et al., was then employed to identify key themes and explore relationships between findings. Results 30 out of 457 studies met the inclusion criteria. The review found that socioeconomic status (SES) emerged as the most significant determinant, with individuals from deprived areas experiencing greater barriers to screening, urgent referrals, and treatment access, leading to poorer patient outcomes. Ethnic minorities, particularly Black patients, faced disproportionate reductions in hospital admissions and cancer screening participation. Age-related disparities were also evident, as older adults maintained higher screening rates but faced greater COVID-19 risks, while younger adults from lower-income backgrounds encountered delays in diagnosis and treatment. Conclusions The review highlights that the COVID-19 pandemic has exacerbated existing inequalities in UK cancer care, with SES, ethnicity, and age emerging as key determinants. Targeted interventions are essential, including the establishment of COVID-free “cold sites”, deployment of mobile screening units, and culturally tailored outreach programmes for ethnic minority communities. Strengthening regional healthcare capacity and conducting longitudinal assessments will be crucial in addressing disparities and ensuring equitable cancer care. Future research should focus on the long-term consequences of these disruptions on cancer outcomes and healthcare resilience.
