There are active tests being conducted to determine if the radio-frequency waves from cell phones do or can in fact cause cancer, but so far these studies show no correlation. If you are interested in reading more, here's a Govt issued fact sheet discussing tests and results so far;http://www.cancer.gov/cancertopics/factsheet/Risk/cellphones
Some studies indicate possible higher risks of brain cancer due to too much cell phone use (hours & hours per day) but it hasn't been proven yet. It's just something some scientists suspect & are studying. Cell phones haven't been around long enough to back these concerns, but more may be known 10-20 years from now.
Yes it is true...phones have radiation which can cause cancer... to prevent this you should turn off your phone at night and during the day not keep it in your pocket the whole time. my family member got cancer keeping his phone in his pocket the whole time(bone marrow cancer)
My opinion I can?t say exactly but yes there are probably chances to get a Cancer. By using mobile phones radiation might be cause cancer .They are few active tests being conducted to define that radio frequency waves from cell phones it can cause a cancer.
