Excessive use of cell phones may cause

Directions: Read the following passage and answer the question that follows.

Holding a cell phone to your ear for a long period of time increases activity in parts of the brain close to the antenna, researchers have found. Glucose metabolism — that’s a measurement of how the brain uses energy — in these areas increased significantly when the phone was turned on and muted, compared with when it was off, experts say.“Although we cannot determine the clinical significance, our results give evidence that the human brain is sensitive to the effects of radiofrequency-electromagnetic fields from acute cell phone exposures,”
Clearly there is an acute effect, and the important question is whether this acute effect is associated with events that may be damaging to the brain or predispose to the development of future problems such as cancer as suggested by recent epidemiological studies,”
