Cancer Treatment Centers of America

Cancer Treatment Centers of America (CTCA) operates as a healthcare provider specializing in oncology services across the United States. The organization delivers cancer diagnosis, treatment, and supportive care through its network of treatment centers. Its headquarters is located in the United States of America. CTCA focuses on delivering integrated cancer care that combines medical treatment with patient support services. The organization serves patients seeking specialized oncology care within the U.S. market.

CTCA has experienced several cybersecurity incidents involving phishing attacks that compromised employee email accounts and exposed patient protected health information. In March 2021 an unauthorized party accessed an employee email account, potentially compromising patient names, medical data, and health insurance details for approximately 105,000 individuals while financial records and Social Security numbers remained unaffected. In September 2019 the Southeastern Regional Medical Center reported three phishing incidents over six months that exposed personal data of thousands of patients across separate events, again without Social Security numbers or financial details being involved. Earlier in March 2019 a phishing attack compromised an employee email account containing patient health information, marking a recurrence of similar incidents within a short period. A December 2018 cyber incident was noted but no specific details were provided. In response to these breaches CTCA secured the affected accounts, implemented additional security controls, notified affected individuals, and reinforced employee cybersecurity training. These events underscore the organization’s handling of sensitive health information and the importance of robust security measures in healthcare settings.
