Cell Phones and Cancer Risk Fact Sheet - NCI
Why has there been concern that cell phones may cause cancer? Is the radiation from cell phones harmful? Has the incidence of brain and central nervous system cancers changed during the time cell phone use increased? How is radiofrequency radiation exposure measured in studies of groups of people?
Electromagnetic Fields and Cancer - NCI - National Cancer Institute
Few studies have examined cancer risk in children living close to cell phone base stations or radio or television transmitters. Mobile phone base stations transmit and receive radiofrequency signals to and from mobile phones near the station.
Risk Factors: Radiation - NCI - National Cancer Institute
Mar 7, 2019 · Ionizing radiation includes radon, x-rays, gamma rays, and other forms of high-energy radiation. Lower-energy, non-ionizing forms of radiation, such as visible light and the energy from cell phones, have not been found to cause cancer in people.
Cellular telephones and cancer risk - NCI
Hand-held cellular telephones are used close to the head and there is concern that the radiofrequency (RF) energy produced by these devices may affect the brain and nervous system tissue in the head. Researchers have focused on whether RF energy can cause malignant (cancerous) brain tumors such as gliomas (cancers of the brain that begin in the ...
Teléfonos celulares y el riesgo de cáncer - National Cancer Institute
Los celulares emiten radiación por radiofrecuencia dentro del espectro electromagnético. Los celulares de segunda, tercera y cuarta generación (2G, 3G y 4G) usan frecuencias de entre 0,7 y 2,7 gigahercios (GHz). Los celulares de quinta generación (5G) usarán frecuencias de …
Oral Complications of Cancer Therapies - NCI
Oct 15, 2024 · Oral complications may be caused by the treatment itself (directly) or by side effects of the treatment (indirectly). Radiation therapy can directly damage oral tissue, salivary glands, and bone. Areas treated may scar or waste away. Total-body radiation can cause permanent damage to the salivary glands.
Definition of non-ionizing radiation - NCI Dictionary of Cancer Terms
A type of low-energy radiation that does not have enough energy to remove an electron (negative particle) from an atom or molecule. Non-ionizing radiation includes visible, infrared, and ultraviolet light; microwaves; radio waves; and radiofrequency energy from cell phones.
Low Dose Ionizing Radiation Shown to Cause Cancer in Review of …
Jul 13, 2020 · Low dose ionizing radiation causes solid cancer and leukemia, according to an international team of experts following a bias assessment and meta-analysis of 26 epidemiological studies. Results were reported in a JNCI monograph published July 2020.
FDA Says Data Doesn’t Link Cell Phones to Cancer
Jun 16, 2020 · The Food & Drug Administration’s recent scientific literature review concludes that “the weight of nearly 30 years of scientific evidence has not linked exposure to RF [radio frequency] energy from use of cell phones to health problems, such as cancer.”
Cell Phones and Cancer Risk - NCI
Dr. Annsi Auvinen presents an overview of cell phones and cancer risk, including an introduction to RF-EMF and cellular phones; issues in epidemiological studies of cellular phones; results of major epidemiologic studies; analyses of tumor locations; and incidence trends.
