NavigatingCancelEventArgs.IsCancelable Property

In Windows Phone applications, you can use this property to determine whether the navigation system will ignore the Cancel property. This happens whenever the navigation destination is an external location, including other applications, launchers, and choosers. This also includes backward navigation that exits the application. However, you can cancel backward navigation in a PhoneApplicationPage.OnBackKeyPress method override.
