Witnesses before a Senate Committee testified about research into cell phones use and its potential impact on human health, as well as the potential side effects such as brain and salivary gland tumors.
In 2008, cell phones were identifies as a contributor to salivary gland tumors. Dr. Siegal Sadetzki, who testified in September 2009 at the U.S. Senate Hearing, is the Principle Investigator of the study that made this finding.
The report states that your risk of getting a parotid tumor on the same side of your head that you use for listening to the mobile phone increases by :
- 34 percent if you are a regular cell phone user and have used a mobile phone for 5 years.
- 58 percent if you had more than about 5,500 calls in your life-time.
- 49 percent if you have spoken on the phone for more than 266.3 hours during your life-time.
