Fish intake and risk of melanoma in the NIH-AARP diet and health study

Habitual consumers of tuna and non-fried fish may be at risk of suffering from malignant melanoma-the most lethal form of skin cancer.

This study examined the correlation between fish intake and the onset of skin cancer. Researchers charted fish consumption against skin cancer diagnoses in a study population comprising of more than 400,000 American men and women. 

Researchers found a high rate of malignant melanoma—the deadliest form of skin cancer—among lovers of tuna and non-fried fish. This study provides material evidence that high dietary ingestion of tuna and non-fried fish may promote the development of skin cancer.
