Does electric blanket cause cancer or just a myth ?

Myth: There was a 'pop' / 'scare' claim in the late 1980's / early 1990's suggesting electric fields cause cancer and everything else. Nobody showed a mutagenic or promoter effect. Several huge good studies found no link to cancer empirically from electric fields. If you design a bad study focused on exposures people remember, you can link anything to anything.

Myth.: I have nothing to add to the fine answer already given, but since some on this site are saying electric fields apparently can do anything to anybody and can cause every ill known to man. I feel I have to weigh in on with sanity. With cigarettes, there was an epidemic of a formerly rare cancer (lung). With cell phones, brain cancer didn't change. Risk is approaching zero.
