Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known. Research this issue, and summarize what's known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?

Cellphones emit radio frequency radiation that is known to penetrate the human body. This is a type of electromagnetic radiation and the human body absorbs this kind of energy. There is only a limited amount of the absorbed radiation before it is considered dangerous. Since cellphones are mostly utilized by placing them next to the ears, there is a higher risk of having brain tumors. According to the Interphone Study, longer usage of cellphone puts the user at forty percent more risk of having gliomas, a deadly malignant tumor that can be found in the brain or spinal cord.
