I am concerned about getting cancer using my Apple Watch

There is no credible evidence that wearing an Apple Watch increase the risk of cancer. If you are concerned about RF emissions please see my response to another user in thread https://discussions.apple.com/thread/250348243?answerId=250659345022#250659345022 and consider that the radio signal is directed away from the wearer’s arm (the back of the watch) because any signal dumped into the wearer is wasted energy.

If you are concerned about radiation that you are exposed to nearly every day that truly can cause cancer, make sure you use lots of sunscreen. But your watch is not a problem.

I just read a report in JAMA that sunscreen enters the blood stream within a day.

Just reviewed the article. Very, very preliminary. A total of 24 subjects under "indoor conditions without exposure to heat, sunlight, and humidity". I'll wait until there's something a bit more definitive before I stop wearing sunscreen! ;-)

I edited my post while you were posting. It's interesting but not something I'm going to worry about yet. I was, once upon a time, a redhead and I've still got the freckles to prove it. I worry a lot about skin cancer.

Have you read something that worries you?

Do you have a TV? Computer? Wireless keyboard? Mouse? Microwave oven? TPMS in your vehicle? Live in a town with cellular service? Cell phone? Cordless telephone?

I don’t know. I didn’t read the rest of it because, with my medical issues, I can’t go to the beach.

About the only thing I could suggest is to not use an Apple Watch. The irrational fear of a life threatening disease will greatly lessen the benefits of an Apple Watch.

Yes. Lots of articles saying it causes cancer.

They're wrong. Don't trust what you find with Google. Talk to your doctor.
