Yes. But you can prevent it.

Cell-phone use puts the lives of millions of Americans — and perhaps billions worldwide — at risk in a variety of ways, from cancer to road safety.

Although some dispute findings of a variety of studies, here are nine ways cell phones might influence your health in a negative way:

1) Brain tumors. Although the Food and Drug Administration says cell phones aren’t a cancer risk, some experts point to research that indicates a link between cell phones and three types of tumors: glioma (the type Senator Kennedy has); cancer of a salivary gland near the ear called the parotid; and acoustic neuroma, which is a tumor found near the ear. An Israeli study found a 58 percent increase in risk for parotid tumors among people who relied heavily on their cell phones. And a Swedish study found the risk for glioma and acoustic neuroma doubled after ten years of heavy use.

2) Fertility. A study found that men who used cell phones for an hour a day had lower sperm quality, and those who use their cell phones for more than four hours a day had the lowest quality of sperm.

3) Insomnia. A recent study found that talking on a cell phone for 30 minutes doubled the time it took for a person to fall asleep.

4) Blackberry Thumb. Sending too many text messages can cause sore thumbs.

5) Mobile Phone Dermatitis. Some cell phones contain nickel, a common allergen that can cause an acidic red, itchy rash.

6) The Dirty Doctor. Studies showed that 94.5 percent of doctors’ cell phones were contaminated by at least one type of bacteria, including MRSA “superbugs” — those resistant to antibiotics.

7) Driving Hazards. Researchers have found that talking on a cell phone — or even just listening — reduced brain activity that should have been focused on driving by 37 percent. Hands-free devices don’t help. Using a cell phone increases the odds of having an accident by 400 percent, studies show.

8) Talking and walking. Children not only are more likely to be injured crossing the street if they’re talking on a cell phone but also more likely to be hurt in other ways. A 15-year-old recently fell into an open manhole cover while texting.

9) Hearing. Millions of people store their favorite music on their mobile phones. Some MP3-enabled devices are capable of an ear-bursting 100 decibels, the same range as blenders, power mowers, and motorcycles.

10) Cell phones emit harmful radiation ranging from 5 milligause to over 100 milligause. The EPA has declared any radiation over 3 milligause is cancer causing.

According to Dr. Robert O. Young, Director of Research at the pH Miracle Living Center, "the magnetic fields in all cell phones emit frequencies that are harmful to health and cancerous causing. This form of invisible acidic pollution emitted by cell phones is the single most dangerous toxin ever invented by man! The use of cellular technology will be considered in the near future as toxic and harmful to health as cigarette smoking."

Cell phones wont cause any health problems.

If you use low branded cell phones which is the exposure of great radiofrequency energy (RF). This may trouble your health . Check with the websites for more details.

cellphones do cause brain tumour if you spend lots of time on mobile

ill effect on heart if you keep mobile near your chest

i haven't heard of any cancer case because of mobile

There have been studies showing slight increases in the frequency of various types of cancer as cell phone use has increased. However, other factors have changed over time as well, and there is no way to tell for certain whether it's increased cell phone use or increased tobacco chewing which is responsible for the increase in salivary gland cancers in the past few years. Other studies have shown no significant change in cancer rates associated with cell phones. Since it's the electromagnetic radiation from the cell phone antenna that is supposedly responsible for the cancers, keeping the antenna away from your head or using an extensible antenna is an effective way to minimize exposure.
