Eating two portions of fish per week has been linked to an increased risk of skin cancer, despite it being the nutritional recommended daily allowance.
According to a new study, eating this amount of fish each week could be putting people at risk of malignant melanoma - the deadliest form of skin cancer.
However, the NHS advises that a healthy, balanced diet should include at least two portions of fish a week, with a serving weighting 140g (4.9oz).
