HC Deb 25 July 1980 vol 989 c449W
Mrs. Renée Short

asked the Secretary of State for Social Services what evidence there is which indicates an increase in the incidence of cancer amongst those who eat fish; what further research is being carried out into this; and if he will make a statement.

Dr. Vaughan

There is no direct evidence to suggest that a diet containing a high proportion of fish is associated with an increased incidence of cancer. Possible correlations between diet and cancer incidence are being intensively studied throughout the world.
