Cancer Treatment Centers of America has notified over 104,000 patients of its Midwestern Regional Medical Center of a data breach that potentially leaked their personal protected health information.

Cancer Treatment Centers of America reported suspicious email activity on their servers in January 2021. The healthcare provider secured the network and contacted a security firm to investigate the data breach. The investigation showed that the cyberattack accessed the email account for almost a week, and may have compromised the following:

  • Patient names
  • Medical insurance data
  • Account numbers
  • Medical record numbers
