Cell Phone and Brain Cancer
Population-based studies have not find the link between cell phones and brain cancer, but a recent study finds that the energy from cell phone can affect the activity of the brain. Holding a cell phone to our ear for a long period of time will increase the activity of some parts of the brain. A measurement of how the brain uses energy, known as glucose metabolism, increased significantly when the cell phone was turned on and muted. Although the researchers cannot determine the significance, the result gives evidence that the brain is sensitive to the electromagnetic fields, especially from acute sell phone exposure.
Although the study cannot draw any conclusions about long-term effects, other researches are revealing a more significant result. The research said there is an acute effect and the question is whether the condition is associated with events that may be damaging the brain or predispose to the development of future health issues, such as brain cancer.
There have been many studies evaluating the potential link between cell phone and brain cancer, but the result is often inconsistent. However, few researchers have looked at the psychological effects that electromagnetic and radiofrequency fields from cell phone can have on brain tissue. Some of the researches revealed that the blood flow can be increased in some regions of the brain during cell phone use. There are also researchers who scan some patients to know the effects of cell phone exposure. However, the result of the researches is not quite satisfying because there is no clear evidence show that cell phone can cause brain cancer.
