Since the Science is not settled... I still won't put a wireless earbud so close to my brain, and I'm especially worried about people doing this over extended periods.  Personally I try to use a wired earbud when I'm using my cell phone.

But I'm overly cautious I guess.  I wear a mask when I go to the store and I use list specific email addresses - so ignore everything I say on this subject.

If you are going to cite that American Cancer Society article, you should cite all the relevant parts. The parts you skipped are bolded. 

RF waves don’t have enough energy to damage DNA directly. Because of this, it’s not clear how RF radiation might be able to cause cancer. Some studies have found possible increased rates of certain types of tumors in lab animals exposed to RF radiation, but overall, the results of these types of studies have not provided clear answers so far.

A few studies have reported evidence of biological effects that could be linked to cancer, but this is still an area of research.

In large studies published in 2018 by the US National Toxicology Program (NTP) and by the Ramazzini Institute in Italy, researchers exposed groups of lab rats (as well as mice, in the case of the NTP study) to RF waves over their entire bodies for many hours a day, starting before birth and continuing for at least most of their natural lives. Both studies found an increased risk of uncommon heart tumors called malignant schwannomas in male rats, but not in female rats (nor in male or female mice, in the NTP study). The NTP study also reported possible increased risks of certain types of tumors in the brain and in the adrenal glands.

While both of these studies had strengths, they also had limitations that make it hard to know how they might apply to humans being exposed to RF radiation. A 2019 review of these two studies by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) determined that the limitations of the studies didn’t allow conclusions to be drawn regarding the ability of RF energy to cause cancer.

Still, the results of these studies do not rule out the possibility that RF radiation might somehow be able to impact human health.

The majority of science to date finds no causal relationship between EM radiation and cancerous mutations. If someone wants to claim otherwise, scientific proof is required.

RF emissions are absorbed by the human body. Your kitchen microwave works at
the same frequency as your 2.4Ghz wifi. We all know it's a bad idea to put your
head in a microwave oven.

The hypothesis that RF may cause damage to human DNA is not at all conspiracy. The
fact that we haven't been able to identify a factual relationship, does not mean

On the contrary. Few people are more exposed to higher-powered RF radiation
than a MW techie. That would make them an excellent subject for scientific
research. Dismissing a medical professional's opinion based in your own
firm beliefs is counterproductive to the advance of scientific knowledge.

Thanks,
