I always knew cancer caused people to use cell phones!
Edit: on a serious note, the confidence interval for malignant tumors is an odds ratio of 1.2-3.4, although a quick google finds more recent studies (I.e.: not based off of 1990s cell phones) are even lower.
That’s not how odds ratios (or research) work. The compares groups of cell phone users and non-cell phone users.
With that being said, we’ve always known cell phone use has a correlation with very slightly increased cancer rates. That shouldn’t be controversial. It’s not concluding that there’s a direct cause or even, if they did cause it, that it’s from RF.
