# Icon Oncology Group (Icon Cancer Centre)

Data breach — Low

Icon Oncology Group, which operates the Icon Cancer Centre network in Australia, announced on 12 October 2026 unauthorised access to patient information held on a supplier's system. According to trade press, a threat actor allegedly offered more than 31,000 documents for sale on an underground forum. The organisation states these are discrete documents tied to correspondence, not complete patient files. At this stage only Australia appears to be affected. The number of people affected and the precise data types have not been disclosed.

Correspondence documents linked to cancer care could let a malicious third party target patients with credible phishing messages.
