This study investigated cancer-related outcomes in people with a LD compared to the general population.  \nMethods A matched cohort study was conducted using linked primary care, hospital, mortality, and cancer registry data from Clinical Practice Research Datalink (CPRD) Aurum. In total, 180,911 individuals with a LD were matched with 3,405,467 controls. Outcomes included urgent suspected cancer (USC) referrals, cancer diagnoses, treatment within six months, and overall survival (OS) post-diagnosis.  \nFindings Individuals with a LD had fewer USC referrals within 28 days of possible cancer symptoms (adjusted risk ratio [aRR] 0.52, 95% confidence interval [CI] 0.49–0.55). LD was associated with several cancers, including sarcoma (adjusted hazard ratio [aHR] 1.98, 1.65–2.39), central nervous system (aHR 3.42, 2.99–3.90), testicular (aHR 2.06, 1.61–2.62), and uterine cancers (aHR 1.69, 1.40–2.05) as well as cancer before age 50 years (aHR 1.74, 1.63–1.86) . Absolute incidence was lower in individuals with a LD compared to without (3396 [1.9%] vs 67,506 [2.0%]) due to increased all-cause mortality (aHR 3.19, 3.12–3.27) . LD was associated with fewer diagnoses via USC referrals (aRR 0.81, 0.76–0.86), fewer treatments within six months (aRR 0.83, 0.80–0.85) and shorter OS (median 4.4 years, 95% CI 3.9–5.1 vs 9.1 years, 8.8–9.5; aHR 1.73, 1.65–1.83) . Melanoma, breast, and prostate cancers were less common but had up to a fourfold increased risk of death after diagnosis in individuals with a LD.  \nInterpretation Individuals with a LD have higher cancer risk, more diagnoses outside USC pathways, fewer treatments, and poorer prognosis. Fewer diagnoses of some cancers, alongside worse outcomes, may indicate underinvestigation. As premature all-cause mortality improves, cancer burden in this population may rise disproportionately.  \nFunding NIHR Greater Manchester Patient Safety Research Collaboration (NIHR204295) .  \nCopyright © 2025 The Authors.
