"Finally, the measurement of cell phone use in most studies has been crude. Most have been case-control studies, which have relied on people’s memories about their past cell phone use. In these types of studies, it can be hard to interpret any possible link between cancer and an exposure. People with cancer are often looking for a possible reason for it, so they may sometimes (even subconsciously) recall their phone usage differently than people without cancer. With these limitations in mind, it is important that the possible risk of cell phone exposure continue to be researched using strong study methods, especially with regard to use by children and longer-term use."Then it goes on to point out that agencies from the FDA to the FCC state that there are no conclusive links to health effects and cell phone EMFs. Cellphone Safety Statements Like This One From The American Cancer Association Would Likely Be Different If These Brain Tumor Cases Were Allowed To Go To Trial . . . and Prevailed.
