In 2011, International Agency for Research on Cancer (IARC) has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic. That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted.
In 2007, Dr. Lennart Hardell, from Örebro University in Sweden, reviewed published epidemiological papers (2 cohort studies and 16 case-control studies) and found that:
·Cell phone users had an increased risk of malignant gliomas.
·Link between cell phone use and a higher rate of acoustic neuromas.
·Tumors are more likely to occur on the side of the head that the cell handset is used.
·One hour of cell phone use per day significantly increases tumor risk after ten years or more.
A publication titled "Public health implications of wireless technologies" cites that Lennart Hardell found age is a significant factor. The report repeated the finding that the use of cell phones before age 20 increased the risk of brain tumors by 5.2, compared to 1.4 for all ages.
