Well, for all your irrational inanimate object avoidance needs, there is a blog keeping track of the Daily Mail's Oncology-related stories: The Daily Mail Oncological Ontology Project.
Unfortunately, it has not been updated since early last year. Indeed, in the last published post, "Lightbulbs give you cancer", the author writes:
"If they continue at this rate they will classify 936 objects into cancer causing or cancer curing in 2008. That’s not counting the Mail on Sunday.
I may have bitten off more than I can chew."
So it looks like the task ended up being simply too formidable for one humble blogger, but I must still commend his/her effort.
Luckily, however, a blog that is regularly updated is Daily Mail Watch, which I recommend instead.
