It's not uncommon that studies done on the same subject often come to vastly different conclusions; and studies on the link between increased risk of cancer and cell phone usage are no exception.
A study published last year in American Journal of Epidemiology has shown that frequent cell phone users face a 50 percent higher risk of developing certain types of tumors. Specifically the risk of developing parotid tumors is increased by 50 percent. The parotid is the largest salivary gland and is located near the jaw and ear where cell phones are typically held.
A 50 percent increased risk of cancer sounds very serious, and any increased chance of cancer should be taken seriously. However, if you stand back and look at the actual numbers the chance of getting a tumor from using a cell phone is still incredibly minute.
A study performed by Mark Kidd showed that in heavy cell phone users the risk of parotid tumors increased from 0.003 percent to 0.0045 percent.
In September of 2007 DailyTech reported that the Mobile Telecommunications and Health Research Programme published a study stating that there was no short-term link between cancer and cell phone use. The report did say that more research was needed into the association of long term cell phone use and cancer.
A study by Dr. Siegal Sadetzki showed that using a cell phone for more than 10 years does in fact raise the risk of brain cancer and notes that children are particularly at risk because of their developing skulls. Sadetzki says, “While I think this technology is here to stay, I believe precautions should be taken in order to diminish the exposure and lower the risk for health hazards.”
Sadetzki recommends using a hands-free device at all times and holding the phone away from the body along with shorter less frequent calls. She also says limit the time kids spend on the phone.
