Do Cellphones Cause Brain Cancer?

Do Cellphones Cause Brain Cancer?
10 comments

Q: I talk on my cellphone a lot… am I at risk for getting brain cancer (or any kind of cancer) from my frequent use?

A: Like a lot of things in science, this is a controversial subject because the evidence we have makes it difficult to determine a true cause and effect relationship.

Cell phones do emit small amounts of radiation, and while it is thought that the amount of radiation is insufficient to cause cellular damage, three studies since 1999 indicate that people who have used cell phones for more than a decade may have as much as three times greater risk of developing brain tumors on the side of the head against which they most often hold their phone—an argument for, at the least, shifting ears regularly or, even better, using an earpiece or the speakerphone feature while chatting.  Even better… turn the phone off and put it down for a while.

Why is this such new news to so many people?? When cell phones first hit the scene some 15 to 20 years ago, it was widely reported that they could possibly cause brain cancer in about 20 years, but a long-term study had to be done. Well, that time is here and those who figured 20 years was far in the future, are now afraid. The thought of brain cancer scared me to death, so I've NEVER owned a cell phone. I live in a suburb of L.A., and I've survived quite nicely without one. I have three grown children now who were young when cell phones were invented, and they don't own one, either! I have landlines in about four rooms in my house, and that's it!

Regardless of what anyone tells you(including main stream media) cell phones cause cancer along with other problems. The cell phone industry makes a ridiculous amount of money each year, so they are not going to be truthful about it's negatives on health. Remember people, its always about the money!

Cell phones should be at least 3 feet away from any body part when the phone is not in use.

You think it was a big when tobacco products were found to cause cancer....just wait until the word gets out about and against the multi-billion dollar cellular phone industry....which is one reason the truth has been and will be suppressed for so long. $$$$$$$$$

I suppose it is more of an issue for men, but long before all the buzz on cellphones causing brain cancer started coming out I remember reading several items about the possibility of cell phones causing testosterone depletion.

All I know is that if I don't use my ear piece, after about 5 minutes my ear feels hot and starts to hurt. I get ear infections from time to time and assumed it's because of that. But, after hearing of the radiation dangers over the last couple years, it makes sense that the sensation I feel is akin to sticking my ear in a microwave. Better safe than sorry :)

The site below lists ALL the brain tumour and cell phone studies to date.

Www.wiredchild.org

A meta analysis of the 11 studies which include longer term users (>10 years) shows a doubling of risk, which is thought to be an underestimate.

There have been recent reports on Australian TV and now action by the French government

Hey, money+power=market power. It's how it's been for a while. As for them making you more likely to get cancer... I'm sure this is something that will affect my mom, since she's on hers all the time but with me... I'm almost never on the thing. I IM people on the computer before I use the phone, if I can. Moderation is probably key. Now, with how they make cell phones... if we want to get a safer technology... well, that's not even in the running, probably. Someone has to first get it in their head to research for one, then figure it out and get out a lot of the bugs in the system, then make it marketable. It'll be out on the market for a while before most of us would be able to afford it... etc. I wish it was different but...

It seems today everything can cause cancer. Well, with cell phones it seems those hands free set ups are becoming critical to one's potential survival...now to buy a lead lined case to wear on my belt so the radiation does not sterilize me.

It wouldn't surprise me at all if they caused brain cancer. What about possible dangers of carrying them in one's pocket? Driving in the car with the phone on is unhealthy...I got my first cell phone in 1993 but didn't use one regularly until 2002. Cell phones and the towers DO worry me. The cell companies have money and power so they can do whatever they want. It isn't right.
