No salivary gland cancer risk found from early phone use, but study cannot address today's heavy long-term smartphone usage patterns.

Plain English Summary

Summary written for general audiences

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.

Study Details

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.

Quick Questions About This Study

A Swedish study of 267 salivary gland tumor patients found no increased cancer risk from cell phone use. Risk levels remained essentially unchanged whether people used analog phones, digital phones, or cordless phones, though long-term heavy use wasn't fully evaluated.
Research shows cordless phones don't increase salivary gland cancer risk. A study comparing 267 tumor patients to over 1,000 healthy controls found no association between cordless phone use and cancer development in the salivary glands.
Current evidence suggests phone radiation doesn't harm salivary glands in your mouth. Swedish researchers found no increased tumor risk from any type of phone use, including analog, digital, and cordless phones, in a study of over 1,300 people.
Phone use doesn't appear to increase salivary gland tumor risk based on current research. A comprehensive study found risk levels of 0.92 for analog phones, 1.01 for digital phones, and 0.99 for cordless phones, showing no significant increase.
Mobile phone use doesn't appear to affect salivary glands according to Swedish research. The study of 267 tumor cases and 1,053 controls found no association between phone radiation and salivary gland tumors, regardless of phone type used.
