2.  Cell phones work by sending signal to nearby cell towers using RF waves. Many people are concerned because at very high levels, RF waves heat up body tissues.

3.  RF waves send from the antenna, which, when you use, is near the head. (Not seen in smart phones, but are in them) People since 2011 are a greater a person’s expected risk to exposure to RF energy. The body tissues closest to the phone absorb more energy than tissues farther away.

4.  Several major studies show no relationship between cell phones and cancer at this time. However, since the information available is based on short- term studies, the impact of many years of exposure is not known.  The amount of time people spend on cell phones has increased dramatically. This will be taken into thought during recent and future studies. Research continues to consider whether there is a relationship between long-term cell phone use and slow-growing tumors in the brain or other parts of the body.
