cell phone, cellular phone

A portable telephone, used in the health professions in, for example, ambulance-to-hospital communications and in 12-lead electrocardiogram transmission in some emergency medical systems. Many people speculate that the use of cellular phones may increase the risk of cancers of the brain (such as gliomas or meningiomas), but no correlation between moderate usage and cancer has been definitively identified. In 2011, the International Agency for Research on Cancer (IARC) classified mobile phone radiation as Group 2B (possibly carcinogenic), not Group 2A (probably carcinogenic). That means that there may be some risk ...
