Cell phone usage is a leading cause of brain cancer.

I will use two arguments for this debate1) It is still disputed whether or not cell phones cause brain cancer2) Something cannot be the leading cause of brain cancer if it does not cause it, or if it is simply not the LEADING cause1) There have been countless studies trying to see if cell phones do cause brain cancer.... And there is very conflicting evidence showing any correlation between cell phone use and brain cancer. Sources below all show how cell phones are not linked to brain cancer"In the largest study yet of its kind, Danish researchers have found no correlation between use of cellphones and risk for brain tumors in adults."http://www.theblaze.com..."Tumor rates in northern European countries have remained steady through 2008 despite widespread cell phone use"http://www.mobiledia.com..."One of the largest and longest studies on the subject finds no more brain tumors among people who had cell phones over 17 years than among people who had no cell phones."http://news.yahoo.com..."350,000 people ages 30 and older and found there was no difference in cancer rates between longtime cell phone "subscribers" and those who didn't have a phone,"http://health.usnews.com..."to date there is no evidence from studies of cells, animals, or humans that radiofrequency energy can cause cancer."http://www.cancer.gov..."The research team analyzed the survey data and couldn't find any link between cell phone usage and brain tumors"http://gizmodo.com..."It's highly unlikely that cell phones cause cancer because they emit "non-ionizing radiation" which is very weak and doesn't really affect living cells"http://articles.businessinsider.com...;"A long-term study of Danish mobile phone use has unequivocally determined that there is no connection between mobile phone use and various cancers of the brain"http://www.itwire.com..."Further research has been published suggesting there is no link between mobile phones and brain cancer."http://www.bbc.co.uk..."In most studies patients with brain tumors do not report more cell phone use overall than the controls."http://www.cancer.org..."A new study has revealed that children and adolescents who use mobile phones are not at a statistically significant increased risk of brain cancer compared to their peers who do not use mobile phones."http://articles.timesofindia.indiatimes.com..."Many experts agree that to date, there is no conclusive evidence that links cell-phone use to brain cancer"http://www.usaweekend.com...-"5 billion cell phone users globally, representing nearly three-quarters of the world's population. However, the incidence and mortality rate of brain and central nervous system cancers has remained virtually flat since 1987"http://abcnews.go.com...So the point is, Cell phones do not definitively cause Brain Cancer2) The second thing I want to address is the current list of leading causes of Brain cancer in no particular order - Exposure to radiation like nuclear power plant workers - Exposure/Use of Formaldehyde, - Exposure to Vinyl Chlorides that affects people who manufacture certain types of plastic - Exposure to Acrylonitrile that affects people who manufacture certain types of textiles and plastics - Studies thus far have not found an increased risk of brain tumors among people who use cell phones.http://www.medicinenet.com...http://cancer.emedtv.com...So cell phones are not proven to cause Brain cancer and as of right now it is most certainly not the leading cause of brain cancer.
