Most of us depend on cell phones every day. Some people wonder if cell phones can cause health problems. Here’s what you should know about cell phones and your health.

Common Questions
Can using a cell phone cause cancer?
There is no scientific evidence that provides a definite answer to the question. Some organizations recommend caution in cell phone use. More research is needed before we know if using cell phones causes health effects.
Do cell phones give off (emit) radiation?
Yes – cell phones and cordless phones use radiofrequency (RF) radiation to send signals. RF radiation is different from other types of radiation (like x-rays) that we know can be harmful. We don’t know for sure if RF radiation from cell phones can cause health problems years later.
To be sold in the United States, equipment that transmits RF radiation must meet exposure limits set by the Federal Communications Commission (FCC). These limits are designed to reduce and ensure that they do not exceed the RF exposure standards developed by the National Council on Radiation Protection and Measurements (NCRP) which FCC guidelines and rules are based upon.
The FCC states that current evidence does not show that using wireless devices such as cell phones are a carcinogen (A carcinogen is an agent that causes cancer).
Should people stop using cell phones?
At this time we do not have the science to link health problems to cell phone use. Scientific studies are under way to determine whether cell phone use may cause health effects. It is also important to consider the benefits of cell phones. Their use can be valuable in an urgent or emergency situation – and even save lives.

What research is being done to learn more about cell phones and health?
Scientists are continuing to study the possible health effects of cell phone use to explore whether current safety standards for RF radiation exposure with wireless devices are adequate. For example, experts are currently looking into how cell phones may affect:
- Some types of tumors (a lump or growth)
- Our eyes
- Sleep
- Memory
- Headaches

Cell phone tips
To reduce radiofrequency (RF) radiation near your body:
- Get a hands-free headset that connects directly to your phone.
- Use speaker-phone more often.
In the past, RF radiation interfered with the operation of some pacemakers. If you have a pacemaker and are concerned about how your cell phone use may affect it, contact your healthcare provider.
