Thanks to Murthy for sending this one. BBC has a story , where Swedish researchers found that using your cell phone for 10 years or more increases the risk of ear tumours by four times! The Karolinska Institute study of 750 people found the risk of acoustic neuroma rose by 3.9 times on the side of the head the phone is used. There was no increase in risk on the other side of the head - giving an overall rise in risk of 1.9 times. Acoustic neuroma is a benign tumour in the auditory nerve, which can cause brain and nerve damage. It affects one in 100,000 people.
Maybe its about time you thought of using a hands-free (be it wired or wireless), its not only safer while driving but apparently you won’t have things growing out of your ear!
