Does being in bed with an electric blanket cause cancer?

Electric blanket and cancer

I've been told that being in bed with an electric blanket switched on can cause cancer. Should I avoid using an electric blanket?

Our answer

Claims about electric blankets causing cancer have been around for many years, however there is no conclusive evidence of risk. Of the seven specific studies on exposure to electromagnetic fields from electric blankets and cancer risk, six found no evidence of a link while one study found a slight increase in risk. On this evidence, the level of risk, if it exists, would be considered very low. People who are nonetheless concerned should be advised to only use their electric blankets to warm their beds before they get in, then turn them off when they go to bed.
