Higher fish consumption may be associated with increased melanoma risk

It defies the belief.

This article published in Science Daily claims that high fish consumption (Tuna in this study) may be associated with increased melanoma risk.

“Those whose median daily tuna intake was 14.2 grams had a 20% higher risk of malignant melanoma and a 17% higher risk of stage 0 melanoma, compared to those whose median daily tuna intake was 0.3 grams”

It defies the belief.

Accordign to the National Fisheries Institute, “The European Union, the United States and Japan are the largest consumers of canned tuna, using about 51 percent, 31 percent and 6 percent, respectively, of the world’s canned tuna products.”

Yet, Japan has very few cases of skin cancer, while Australia, which has the most skin cancer cases in the world, is not on that list.

Correlation and causation are two very different things. Although there may be a mathematical correlation, I can’t understand how there can be a cause-effect relationship.

Keep eating fish. They are good for you. I can’t see how they can cause melanoma.
