Does Radiofrequency Radiation From Mobile Phones Affect the Formation of Parotid Gland Malignancy? An Experimental Study

Abstract

Overview

With the global increase in mobile phone usage, concerns have arisen regarding the potential biological effects of the electromagnetic fields (EMFs) they emit. The parotid gland, being closest to mobile phones during use, may absorb significant levels of this radiation. This study aimed to evaluate the effects of 1800 MHz electromagnetic fields on the parotid gland in a rat model.

Methods

• 21 Sprague-Dawley Albino rats were randomized into three groups: control, 6 hours/day EMF exposure, and 12 hours/day EMF exposure, all for 30 days.
• Exposure was generated using an 1800 MHz microwave source simulating mobile phone conversation mode.
• After 30 days, parotid glands were studied histopathologically and immunohistochemically. Biochemical analysis measured total antioxidant and oxidant levels.

Findings

• There was a notable increase in tissue degeneration in EMF-exposed rats.
• Immunohistochemical data revealed a significant rise in apoptotic index for both exposure groups (P = .001, P < .001).
• Intranuclear inclusions were identified via electron microscopy.
• Biochemical and histopathological changes intensified with longer exposure times.

Conclusion

This experimental study demonstrates that 1800 MHz electromagnetic field exposure, simulating mobile phone use, induces adverse histopathological and biochemical alterations in the parotid gland of rats. The degree of damage correlated with increased exposure time. These findings underscore a connection between EMF exposure from mobile devices and potentially harmful health effects, particularly in tissues in close proximity to the source. The results emphasize the necessity for further research and caution regarding EMF exposure from everyday electronic devices.
