Planned Parenthood of the Heartland says a potential data breach may have affected 2,506 patients in Dubuque who have had records there between 2008 and 2014.

Planned Parenthood said Tuesday the data breach may have been accessed by unauthorized parties during the April 2016 closure and sale of the Dubuque facility at 3365 Hillcrest Road.

Planned Parenthood said it has notified patients and provided thorough instructions.

Potential information compromised includes patients’ full name, date of birth, mailing address, insurance information, social security number, medical record number, diagnosis, treatment, and lab results.
