As noted above, the RF waves given off by cell phones donât have enough energy to damage DNA directly or to heat body tissues. Because of this, many scientists believe that cell phones arenât able to cause cancer. Most studies done in the lab have supported this theory, finding that RF waves do not cause DNA damage. This would be expected if cell phone use caused brain tumors. 2  Most studies do not show that brain tumors occur more often on the side of the head where people hold their cell phones. 3  This might also be expected if cell phone use caused brain tumors.
