A cohort study of 119,480 elderly patients with atrial fibrillation revealed a strong association between post-anticoagulation bleeding and new cancer diagnoses.

**Key Findings:**

- Within 2 years of starting anticoagulants, 21.8% of patients experienced bleeding, and 4.9% were diagnosed with malignancy.
- Bleeding significantly increased cancer risk (HR: 4.0). 
- Higher risks for malignancies like gastrointestinal (HR: 15.4), genitourinary (HR: 11.8), and respiratory (HR: 10.1). 
- Notably, cancers were detected at an earlier stage in patients with antecedent bleeding.
