The impact of microwave emissions from wireless phones on potential cancer risks is a growing concern among people these days. In order to scientifically prove the relationship between the long-term use of cell phone and its connection with certain tumors, the Interphone study group and the Hardell group in Sweden was made part of the experiment and later evaluated.
The glioma odds ratio from the meta-analysis regarding brain tumors came out to be (OR)=1.0, while 95% confidence interval being (CI)=0.9-1.1. OR rose to 1.3 and 95% CI=1.1-1.6 with 10 year latency period and OR=1.9, 95% CI=1.4-2.4 when there was a great amount of risk for ipsilateral exposure on the same side where the tumor is located. OR=1.2, 95% CI=0.9-1.7 for contralateral exposure on the opposite side. OR=1.0, 95% CI=0.8-1.1 for acoustic neuroma but it climbs to OR=1.3, 95% CI=0.97-1.9 with 10 years latency period. OR=1.6, 95% CI=1.1-2.4 was calculated for ipsilateral exposure, while it came out to be OR=1.2, 95% CI=0.8-1.9 for contralateral exposure.
There wasn’t a consistent pattern of an increased risk related to meningioma. In the studies from the Hardell group, at time of first use of wireless phones, the age group of <20 years were at the greatest risk. No concrete link was found between the salivary gland tumors including non-Hodgin lymphoma and testicular cancer and wireless phones use. One study on uveal melanoma yielded for probable/certain mobile phone use OR = 4.2, 95% CI = 1.2–14.5.
It was not possible to evaluate a study on intratemporal facial nerve tumor because of the limitations in the methodology. To conclude it, it was found that after 10 years of using cell phones, the risk for glioma and acoustic neuroma increases. The current standard for exposure to microwaves while using cell phones needs to be revised as it is not safe for long-term exposure.
