Important.
The researchers found that compared to those whose median daily fish intake was 3.2 grams (.11 ounces), those whose median daily intake was 42.8 grams (1.5 ounces) had a 22% higher risk of malignant melanoma and a 28% increased risk of developing abnormal cells in the outer layer of the skin only — known as stage 0 cancer or melanoma in situ. A serving size of cooked fish is approximately 140-170 grams (5-6 ounces); a can of tuna is 142 grams (5 ounces).
Higher fish consumption associated with increased melanoma risk, study suggests
A new analysis from a Brown University team shows a connection between eating fish and developing skin cancer, and the researchers say bio-contaminants like mercury are a likely cause.
