New review study finds that heavier cell phone use increases tumor risk
November 2, 2020
A review of research on cell phone use and tumor risk finds that cell phone use with cumulative call time more than 1000 hours significantly increased the risk of tumors.
(Berkeley, CA, November 2, 2020) Today, the International Journal of Environmental Research and Public Health published a systematic review and meta-analysis of the case-control research on cell phone use and tumor risk.
This study updates our original meta-analysis (i.e., quantitative research review) published in the Journal of Clinical Oncology in 2009. The new review examined twice as many studies as our original paper.
“In sum, the updated comprehensive meta-analysis of case-control studies found significant evidence linking cellular phone use to increased tumor risk, especially among cell phone users with cumulative cell phone use of 1000 or more hours in their lifetime (which corresponds to about 17 min per day over 10 years), and especially among studies that employed high quality methods.”

We investigated whether cellular phone use was associated with increased risk of tumors using a meta-analysis of case-control studies. PubMed and EMBASE were searched from inception to July 2018. The primary outcome was the risk of tumors by cellular phone use, which was measured by pooling each odds ratio (OR) and its 95% confidence interval (CI). In a meta-analysis of 46 case-control studies, compared with never or rarely having used a cellular phone, regular use was not associated with tumor risk in the random-effects meta-analysis. However, in the subgroup meta-analysis by research group, there was a statistically significant positive association (harmful effect) in the Hardell et al. studies (OR, 1.15—95% CI, 1.00 to 1.33— n = 10), a statistically significant negative association (beneficial effect) in the INTERPHONE-related studies (case-control studies from 13 countries coordinated by the International Agency for Research on Cancer (IARC); (OR, 0.81—95% CI, 0.75 to 0.89—n = 9), and no statistically significant association in other research groups’ studies. Further, cellular phone use with cumulative call time more than 1000 hours statistically significantly increased the risk of tumors. This comprehensive meta-analysis of case-control studies found evidence that linked cellular phone use to increased tumor risk.

3.5. Exposure–Response Relationship Between Use of Cellular Phones and Risk of Tumors
Table 3 shows an exposure-response relationship between cellular phone use and tumor risk. In the subgroup meta-analysis by time since first use or latency, overall the risk of tumors by cellular phone use non-significantly increased from an OR of 0.97 to 1.29 as latency increased from less than 5 years to 10 or more years. This finding was observed in each subgroup meta-analysis by research group. Especially, statistically significant increased tumor risk was observed for latency of 10 or more years in the Hardell studies (OR, 1.62; 1.03 to 2.57; n = 5; I2 = 39.9%). Similarly, the use of cellular phones non-significantly increased the risk of tumors as the cumulative or lifetime use in years and the cumulative number of calls increased in all studies and in each study group. Remarkably, in the subgroup meta-analysis of all studies by cumulative call time, cellular phone use greater than 1000 hours statistically significantly increased the risk of tumors (OR, 1.60; 1.12 to 2.30; n = 8; I2 = 74.5%). Interestingly, the use of cellular phones overall and in the Hardell studies (OR, 3.65; 1.69 to 7.85; n = 2, especially in the Hardell studies) non significantly increased the risk of tumors with cumulative call time of 300–1000 h and more than 1000 h, while it decreased the risk of tumors in most subgroup meta-analyses of the INTERPHONE studies.
In sum, the updated comprehensive meta-analysis of case-control studies found significant evidence linking cellular phone use to increased tumor risk, especially among cell phone users with cumulative cell phone use of 1000 or more hours in their lifetime (which corresponds to about 17 min per day over 10 years), and especially among studies that employed high quality methods. Further quality prospective studies providing higher level of evidence than case-control studies are warranted to confirm our findings.

Cellular Phone Use and Risk Of Tumors: Systematic Review and Meta-Analysis
This is a really simple one, but it’s easy to forget. If you use an Echo Show device, make sure your camera is disabled or covered when you aren’t using it. Hacking laptop cameras and other webcams is a notorious method of spying on people — one used by governments and individual hackers alike — and keeping your camera disabled is a simple way to protect yourself.
To disable your camera, simply use the physical toggle on each Echo Show device.
While you’re looking at the Alexa Privacy page, another menu worth perusing is Manage Skill Permissions. Here you can scroll down to see which skills (Amazon’s word for apps and features) want access to everything from your street address and contact info to your Amazon Prime payment info. Many of these permissions default to off, but every once in a while, it’s a good idea to check which skills you’ve enabled over the months or years of using Alexa, and if they’ve gained one-time access that you don’t want them to keep forever. To control these permissions, tap More, then Settings, then Alexa Privacy, then Manage Skill Permissions.

With so many complicated discussions surrounding health right now. Here’s something simple you can do today:
1. Move your charging stations out of the bedrooms. This is #1 for a reason. Most people do not realize that they are being exposed to EMFs from the charging cords as well as from the actual phone.

According to the index, there are currently 23 countries tracking their citizens through cell phones, with ‘alternative digital tracking measures’ being active in 22 countries.
A digital rights group is warning that governments worldwide are working with big tech firms to develop software that uses people’s smartphones as a tracking application for health authorities.
The live index also shows that “physical surveillance technologies” are being used in ten countries, and that coronavirus related censorship has been “imposed by 12 governments.” Lastly, the live index shows that internet shutdowns continue in four countries “despite the outbreak.”
Woodhams said that unless these “highly invasive” measures are not tracked, increased surveillance measures will become normalized.
“Without adequate tracking, there is a danger that these new, often highly invasive, measures will become the norm around the world,” Woodhams said in the Business Insider report.
“Although some may appear entirely legitimate, many pose a risk to citizens’ right to privacy and freedom of expression,” adding “documenting the new measures is the first step to challenging potential overreach, providing scrutiny and holding corporations and governments to account.”

A new law requires mobile phone retailers to warn consumers at the point of sale that carrying mobile phones in pockets and bras could present radiation health risks.
Enact the “Cell Phone Right-to-Know” Law by sending the following text to your representatives:
SAMPLE CELL PHONE RIGHT-TO-KNOW LAW
The (town, city or county) of ______________ requires that you be provided the following notice:
“To assure safety, the Federal Government requires that cell phones meet radio-frequency (RF) exposure guidelines. If you carry or use your phone in a pants or shirt pocket or tucked into a bra when the phone is ON and connected to a wireless network, you may exceed the federal safety guidelines for exposure to RF radiation.
Refer to the instructions in your phone or user manual for information about how to use your phone safely.”
In 2008, Tiffany Shlain’s father, Leonard, was diagnosed with brain cancer, and she began to change her use of technology when the two of them were together. “Some days he would have only one good hour,” she later wrote in the Harvard Business Review, “and I didn’t want to be distracted when I was with him, so I’d turn off my cellphone.”
