The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. The advantages of health information technology IT include facilitating communication between health care providers; improving medication safety, tracking, and reporting; and promoting quality of care through optimized access to and adherence to guidelines.
How common is brain cancer? Has the incidence of brain cancer changed over time? Why is there concern that cell phones may cause cancer or other health problems?
Cell phones emit radiofrequency energy radio wavesa form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy. As of Decemberthere were more than This is a nearly threefold increase from the million users in Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion.
However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models. The NCI fact sheet Electromagnetic Fields and Cancer includes information on wireless local area networks commonly known as Wi-Ficell phone base stations, and cordless telephones.
What is radiofrequency energy and how does it affect the body? Radiofrequency energy is a form of electromagnetic radiation.
Electromagnetic radiation can be categorized into two types: Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second.
Electromagnetic frequencies are described in units called hertz Hz. The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. More information about ionizing radiation can be found on the Radiation page.
The frequency of radiofrequency electromagnetic radiation ranges from 30 kilohertz 30 kHz, or 30, Hz to gigahertz GHz, or billion Hz. The human body absorbs energy from devices that emit radiofrequency electromagnetic radiation.
The dose of the absorbed energy is estimated using a measure called the specific absorption rate SARwhich is expressed in watts per kilogram of body weight. Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. The only consistently recognized biological effect of radiofrequency energy is heating.
The ability of microwave ovens to heat food is one example of this effect of radiofrequency energy. However, it is not sufficient to measurably increase body temperature, and there are no other clearly established effects on the body from radiofrequency energy.
Whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain 2the other study 3 found reduced glucose metabolism on the side of the brain where the phone was used.
The authors of these studies noted that the results are preliminary and that possible health outcomes from changes in glucose metabolism are still unknown.
Such inconsistent findings are not uncommon in experimental studies of the biological effects of radiofrequency electromagnetic radiation 5. Some contributing factors include assumptions used to estimate doses, failure to consider temperature effects, and lack of blinding of investigators to exposure status.
How is radiofrequency energy exposure measured in epidemiologic studies? Direct measurements are not yet possible outside of a laboratory setting.Health Risks Associated with Technology The widespread use of technology has led to some important user health concerns.
Some of the more common physical health risks are repetitive strain injuries, computer vision syndrome, and muscular pain. These injuries are on the rise of technology.
