Vehicle emissions a cancer threat?

I WISH to congratulate you on publishing so prominently and so clearly the results of the National Cancer Registry county survey (Irish Examiner, July 4-6).

Because of the relatively short timespan covered, only limited conclusions can be drawn in the Irish context.

However, an important omission from the feature article is that there is a consistent trend upwards in incidence for certain cancers of almost 3% per year.
