Understanding your Mojave Radiation Oncology Medical Group data breach notification letter
If a Mojave Radiation Oncology Medical Group letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Mojave Radiation Oncology Medical Group is a specialized healthcare provider focused on cancer treatment and radiation therapy services. As a medical entity, the organization collects and maintains sensitive patient information, including personal identifiers, clinical health records, and insurance billing details necessary for coordinating complex oncology care. In 2025, the company officially reported a data security incident to the California Attorney General, confirming that unauthorized access to their systems occurred. If you have received a formal data breach notification letter from the medical group, it indicates that your personal or protected health information may have been compromised during this event. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered to those impacted.
What to do after the letter
Confirm the notice is genuine
A legitimate Mojave Radiation Oncology Medical Group notice references the specific incident reported to the California Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
