Golden State Radiation Oncology is a specialized healthcare provider focused on cancer treatment and radiation therapy services. As a medical facility, the organization maintains highly sensitive patient records, including detailed clinical histories, diagnostic imaging, and insurance billing information. 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 organization, it indicates that your personal or protected health information was likely contained within the impacted files. This notice is intended to inform you of the incident, the steps the provider is taking to secure their network, and the resources available to help you protect your identity and medical privacy.
About the Notice You Received
If you received a data breach notification letter, notice, or mailing from Golden State Radiation Oncology, this communication confirms that your personal information was exposed or accessed without authorization.
Under California law (Cal. Civ. Code § 1798.29), companies are legally required to send a written breach notification to every affected resident. This may arrive as a letter in the mail, a formal notification mailing, or an email notice — all are equally valid as evidence of harm.
Your Golden State Radiation Oncology notification letter is more than an informational warning. It is legally required documentation — and the starting point for a potential class action claim against Golden State Radiation Oncology.

Why This Breach Matters
Companies across every industry collect and store personal data as part of normal operations — including Social Security numbers for tax compliance, payment card data for billing, and contact information at minimum. When that data is compromised, affected individuals face risks ranging from targeted phishing attacks and identity theft to unauthorized account access and financial fraud.
California residents are protected by Cal. Civ. Code § 1798.29, which gives you the right to pursue legal remedies when a company fails to adequately protect your data.
Common Questions
I received a Golden State Radiation Oncology breach notice — does it mean my data was stolen?
Yes. Receiving a Golden State Radiation Oncology data breach letter, notice, or notification mailing means your personal information was accessed or exposed without authorization. Companies are only required to send these notices when a confirmed breach occurred affecting your data specifically.
Is there a deadline to act after receiving my Golden State Radiation Oncology notification letter?
Yes. California and federal law impose statutes of limitations on data breach claims. Once a class action lawsuit is filed by another attorney, the window to be a named plaintiff typically closes quickly. Submitting a free case review now ensures you are positioned before those windows pass. There is no cost and no obligation to find out if you qualify.
How much does it cost to pursue a claim?
Nothing upfront. Representation is 100% contingency-based — a fee is only collected if your case results in compensation. If there is no recovery, you owe nothing at any stage.
