Cell Phones Increase Cancer Risk

While the independent research on the effects of microwave radiation emitted by wifi, cell phones and other mobile devices is clear and more than sufficient to prove that exposure at low levels causes DNA damage that can lead to cancer, the wireless industry has paid for studies designed to sow confusion and make people feel comfortable about the risks from microwave radiation.

Even though the World Health Organization classifies microwave radiation as carcinogenic, national health agencies have not taken measures to protect the public nor has the public shown much interest in the risks to their health. The massive lobbying and advertising by the wireless industry holds sway over public opinion and govt. regulation.

A new study published in the journal Antioxidants and Redox Signaling may provide health advocates with more ammunition in the case against microwave radiation.

The study looked for cancer clues in the saliva of cell phone users. Since the cell phone is placed close to the salivary gland when in use, researchers hypothesized that salivary content could reveal whether there was a connection to developing cancer. Comparing heavy mobile phone users to non-users, they found that the saliva of heavy users showed indications of higher oxidative stress — a process that damages all aspects of a human cell, including DNA — through the development of toxic peroxide and free radicals. More importantly, it is considered a major risk factor for cancer.

For the study, the researchers examined the saliva content of 20 heavy-user patients, defined as speaking on their phones for a minimum of eight hours a month. Most participants speak much more, Dr. Hamzany says, as much as 30 to 40 hours a month. Their salivary content was compared to that of a control group, which consisted of deaf patients who either do not use a cell phone, or use the device exclusively for sending text messages and other non-verbal functions.
Compared to the control group, the heavy cell phone users had a significant increase in all salivary oxidative stress measurements studied.

This suggests that there is considerable oxidative stress on the tissue and glands which are close to the cell phone when in use. The damage caused by oxidative stress is linked to cellular and genetic mutations which cause the development of tumors.  However, it can take more than 10 years before the damage results in tumors or other symptoms of illness that a person would notice.
