Chinese researchers in Beijing are seeing some of the highest rates of cancer ever reported in any cell phone study. They have found that long-term, heavy users have rates of malignant parotid gland tumors that are seven to 13 times higher than might otherwise be expected.
The raw data —that is, before being adjusted for other possible risk factors like sex, age, income, smoking status and the like— point to cancer risks that are elevated 10-fold, 20-fold, and even 30-fold, depending on the type of tumor and how heavy cell phone use is defined (see table below). For instance, those who had used mobile phones for over ten years had more than ten times the rate of epithelial parotid gland malignancies, the dominant type of cancer of parotid gland. The risk rose to 20 times that of controls for mucoepidermoid carcinoma, the primary subtype of parotid gland cancer. http://www.emfnews.org/store/http://www.emfnews.org/products.html
