While multiple tattooing experiences may enhance innate immunological vigilance and secretory immunoglobulin A (SIgA) habituation, this permanent exposure is associated with an increased hazard of skin cancer (HR=3.91, 95% CI: 1.42-10.8) and malignant lymphoma (IRR=1.21…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
