View Original AbstractNo salivary gland cancer risk found from early phone use, but study cannot address today's heavy long-term smartphone usage patterns.
Plain English Summary
Swedish researchers studied 267 people with salivary gland tumors and compared them to 1,053 healthy controls to see if cell phone or cordless phone use increased cancer risk. They found no increased risk for salivary gland tumors from any type of phone use, with risk levels essentially unchanged whether people used analog phones, digital phones, or cordless phones. However, the study couldn't draw conclusions about very long-term heavy use since few participants had used phones for more than 10 years.

No association between the use of cellular or cordless phones and salivary gland tumours was found, although this study does not permit conclusions for long term heavy use.
