Study on link between eating fish and getting cancer not conclusive
A several media outlets warned that eating two portions of fish a week increases the risk of malignant melanoma, the most serious form of skin cancer.
The coverage was based on a recent study, analysing data from 500,000 subjects that were followed over an average of 15 years. The study reports a positive association between higher intakes of fish, tuna and non-fried fish and risk of malignant melanoma.
Although ‘’food frequency’’ questionnaires are a validated way of assessing diets, the estimates of fish intake may be inaccurate as they rely on people’s ability to calculate their own food intake.
