What we know
Onsite Mammography operates as a specialized healthcare provider, offering diagnostic imaging services directly to patients and corporate clients. Given the nature of their medical services, the company maintains highly sensitive personal information, including comprehensive health records, diagnostic imaging results, and associated billing details. In 2025, the company officially reported a data security incident to the South Carolina Attorney General, indicating that unauthorized access to their systems may have occurred. If you recently received a data breach notification letter from Onsite Mammography, it confirms that your personal or protected health information was involved in this incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered to you.

After the Onsite Mammography incident: what to do and your options
- What should I do after getting the Onsite Mammography data breach notice?
- Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.
- Did Onsite Mammography offer free credit monitoring?
- Look for an enrollment code in your Onsite Mammography notice. Companies that offer free credit monitoring after a breach usually include it there, with a deadline to activate. Signing up doesn't waive any legal rights you may have.
- Can I sue Onsite Mammography over the data breach?
- It depends on what was exposed, the law in South Carolina and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
- Do I need a Onsite Mammography data breach lawyer or attorney?
- Whether the company's systems were encrypted by ransomware or data was simply taken, the legal question is the same: did it protect your information the way the law requires? An attorney can review your notice for free, and these cases are usually handled on contingency.
- Is there a Onsite Mammography data breach class action lawsuit?
- Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow. This page doesn't confirm that a lawsuit has been filed against Onsite Mammography. You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
- Is the Onsite Mammography data breach letter legit or a scam?
- A notice from Onsite Mammography in the mail matches the breach Onsite Mammography reported to the South Carolina Attorney General on April 22, 2025. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Onsite Mammography through a phone number or website you find yourself.
- How much could a Onsite Mammography data breach settlement or claim be worth?
- There is no set amount, and no Onsite Mammography settlement is confirmed here. In past data breach settlements, payments depended on what data was exposed and on documented losses — fraud, out-of-pocket costs and time spent dealing with the breach. Keep receipts and records; they're what damages claims are built on.
