Aflatoxins in sera from patients with lung cancer

Sera from patients with lung cancer and from healthy donors were screened for the presence of aflatoxins. Significant differences in levels of aflatoxins between the two groups were found. Only 1 of the neoplastic patients with aflatoxins in the serum was a smoker. However the percentage of sera from lung cancer containing aflatoxins is not significant enough to provide evidence for a casual relationship between aflatoxins exposure and development of lung cancer in humans.
