Researchers now say, the study's results are flawed and kids' brains might be more susceptible to cellphone radiation.
In question is whether the radiation from cell phones poses a health hazard to children.
In a new report, published in the journal ... Environmental Health Trust ... Experts say cell phone use more than doubles the risk of brain tumors in children and teens -- especially those who are exposed more often.
"It seems like everyone has a cell phone nowadays, including kids in grade school."
Rylee McQuay, 11, has had a cell phone for five years now. She says she's on it 24-7, and she's not the only one.
Heather Baker told Action News, "They often have them a lot when we're switching classes, they have them most of the time and after school and on the buses, they're always on them."
And that exposure could pose a health problem. A group of researchers say cell phone use more than doubles the risk of brain tumors in children and teens.
Scientists came to this conclusion after disputing a previous study suggesting there's no link between cell phone use and brain tumors.
Some experts are concerned children's developing brains might be more susceptible to cellphone radiation. But some parents are skeptical about the findings.
Fresno parent Lilia Neves said, "For me as a parent, I don't feel it's an issue because I have control over what they use and what they don't use."
Limiting use is important while more research is done on this evolving technology.
"It's always wise with any kind of exposure to radiation, whether it be the sun or sunburn, etc., we don't need a lot of it," Dr. William Ebbeling said. "At the same time, the amount that's coming out isn't that much."
Doctor William Ebbeling is a pediatrician but says parents shouldn't be too concerned with the recent study. "When you look at it, I think it all needs to be taken with a grain of salt, look at the date, I think we need to keep looking, I don't think one particular study is going to answer all the questions."
For now, parents and teens don't seem to be too alarmed.
Tarah Soria said, "If I see it actually happen, I would be worried, because then I would be like, yeah, maybe I should cut it down."
Now health experts say parents could limit kids exposure to radio-frequency radiation by using a head-set, limiting the length of calls, or simply sending a text message instead.
