Correlation between allergy and cancer: a systematic review and meta-analysis.

ABSTRACT: The relationship between allergies and cancer has been a topic of debate for decades. This study conducted a systematic review and meta-analysis of 53 studies to evaluate the association between allergies and cancers. Case-control and cohort studies were analyzed, focusing on cancer incidence. The results showed significant negative correlations between allergies and cancers such as colorectal cancer, lymphoma, pancreatic cancer, leukemia, and brain cancers. For colorectal cancer, the pooled odds ratio (OR) for any allergy was 0.77 (95% CI 0.67-0.87). Asthma was associated with a reduced risk of lymphoma (OR 0.81, 95% CI 0.70-0.94) and gynecological cancers (OR 0.72, 95% CI 0.53-0.97). For Pancreatic cancer, any allergy was associated with an OR of 0.68 (95% CI 0.59-0.77). Hay fever showed
