One in eight women will be diagnosed with breast cancer in her lifetime. Over 16,700 women in New York are diagnosed with breast cancer annually, and about 2,500 women die from breast cancer in New York annually. Early detection saves lives – breast cancer caught at the localized stage, before it spreads beyond the breast, has a 99% five-year survival rate. But when a radiologist misreads a mammogram, a patient may lose precious time.
A delayed diagnosis often pushes cancer to advanced stages with a worsened prognosis, while a false positive can send someone into an operating room for procedures they never needed. This article explains how a misread mammogram can lead to a breast cancer diagnosis gone wrong and what legal options exist under New York law.
Key Takeaways
- Yes, a misread mammogram can lead to a breast cancer misdiagnosis in New York – either through a false negative that delays diagnosis or a false positive that triggers unnecessary treatment.
- Common errors include missed tumors, incorrect BI-RADS scoring, and failure to recommend additional tests, all of which can constitute medical negligence.
- New York patients harmed by a missed breast cancer diagnosis may pursue medical malpractice claims for medical expenses, lost wages, pain and suffering, and emotional distress.
- The statute of limitations for medical malpractice in New York is 2.5 years from the negligent act, though cancer misdiagnosis cases may qualify for limited extensions.
- Below, we walk through how mammograms work, how they are misread, what the legal standards require, and what steps you should take next.
- At The Pagan Law Firm, we carefully evaluate whether a breast cancer misdiagnosis or delayed diagnosis may be linked to a medical error. We work with qualified medical professionals to review imaging, reports, and treatment timelines to determine what went wrong and whether legal action may be appropriate under New York law.

Understanding Mammograms and Their Role in Breast Cancer Diagnosis
A mammogram is a low-dose X-ray used to screen for or diagnose breast cancer. Screening mammograms are routine tests for asymptomatic patients – the American Cancer Society gives women the option to begin annual mammograms at 40 and recommends annual screening starting at 45, while older women and those with risk factors like family history may follow adjusted schedules. Diagnostic mammograms are ordered when a patient reports a breast lump, pain, nipple discharge, or other symptoms.
New York law requires many insurers to cover breast cancer screening and diagnostic imaging – including for high-risk patients – without cost-sharing, though this protection does not extend to self-funded employer plans. No one test can catch everything. Dense breast tissue, overlapping structures, and very small tumors can challenge even experienced readers. That is why doctors often recommend multiple tests and comparison with prior mammograms to improve accuracy.

How Mammograms Can Be Misread or Misinterpreted
Human error remains a leading factor in cancer misdiagnosis related to mammograms. Misinterpretation of mammograms can lead to failure to diagnose cancer, even when images are technically adequate. Radiologists may overlook subtle findings – faint microcalcifications, small asymmetries, or slow-growing masses that require careful comparison with prior imaging.
Dense breast tissue can make it harder to identify abnormalities, increasing the risk of both false negatives and false positives. New York requires providers to notify patients when breast tissue is heterogeneously or extremely dense. Cognitive biases can contribute to reader error in mammography – for instance, a radiologist may anchor on a benign-looking feature and miss a nearby suspicious area. Add miscommunication between radiologists and referring physicians, and the chance of a missed finding grows.
Common Radiological Errors That May Lead to Breast Cancer Misdiagnosis
Not every reading disagreement equals malpractice, but certain recurring errors are strongly associated with breast cancer misdiagnosis:
- False negatives: A false negative occurs when a mammogram fails to detect cancer. Screening mammograms miss about 1 in 8 breast cancers overall, leaving some patients without timely treatment.
- False positives: False positives can lead to unnecessary biopsies and treatments, and can result in significant emotional distress for patients and family members.
- Overdiagnosis: Estimates vary widely, but recent research suggests roughly 15% of screen-detected breast cancers may be overdiagnosed, leading to unnecessary treatments and surgeries – including chemotherapy and radiation a patient never required.
- Inflammatory breast cancer: Because its symptoms can mimic infection, inflammatory breast cancer is frequently misdiagnosed in its early stages, with some studies reporting misdiagnosis rates as high as 40-60%.
- BI-RADS misclassification: Assigning a BI-RADS 3 (“probably benign”) when features warrant BI-RADS 4 delays biopsy and allows cancer to progress.
- Technical errors: Improper positioning of the patient can cause technical errors, and documentation mistakes or failure to recommend follow-up imaging compound the problem.
Breast cancer misdiagnosis can lead to unnecessary treatments and surgeries – or to no treatment at all when cancer is present.
A note on sourcing: the overdiagnosis and inflammatory breast cancer figures both come from ranges in the literature rather than single agreed-upon numbers, so if Pagan’s review process wants pinpoint citations rather than ranges, it’s worth flagging that to them directly, since the underlying research itself doesn’t converge on one number for either.
Standard of Care for Radiologists in New York
The standard of care requires that a reasonably prudent radiologist in New York interpret a mammogram with appropriate skill and diligence. This includes systematic review of all breast quadrants, comparison with prior mammograms when available, accurate BI-RADS scoring, and clear follow-up recommendations. Diagnostic errors, including missed or delayed breast cancer detection, remain a leading cause of malpractice claims in radiology, and healthcare professionals who fail to meet accepted standards when reading imaging may be held accountable under New York malpractice law.
When a Misread Mammogram Becomes Medical Negligence
Not every adverse outcome is medical malpractice. The law asks whether the provider’s conduct fell below the accepted standard. New York medical malpractice claims require four elements:
- Duty of care – a radiologist-patient relationship existed.
- Breach – the radiologist fails to interpret the mammogram as a competent peer would.
- Proximate causation – the breach directly caused harm (e.g., a tumor visible in 2021 goes unreported, leading to a Stage III diagnosis in 2023).
- Damages – the patient suffered measurable losses.
Expert testimony from qualified medical professionals is essential to determine whether the mammogram was misread. An honest diagnostic disagreement within accepted practice may not be negligence, but when a radiologist misreads obvious findings, liability follows.
Consequences of a Delayed or Missed Breast Cancer Diagnosis
A missed diagnosis can halt timely treatment of cancer, and delayed treatment causes cancer to progress to an advanced stage. Patients who should have had a lumpectomy may instead face mastectomy, multi-agent chemotherapy, and radiation – a delayed diagnosis often requires more aggressive treatments.
Survival rates drop sharply once breast cancer spreads beyond the breast and nearby lymph nodes, and progression can lead to metastasis and even death. Emotional and psychological trauma can arise from delayed diagnosis, affecting the patient’s quality of life and straining relationships with a loved one and family members.
Financial burdens can severely impact patients due to escalating medical bills. Breast cancer treatment costs range from $10,000 to $200,000, depending on the stage and the cancer treatment required.
Who May Be Liable in a Misread Mammogram Case?
Multiple parties may share responsibility in breast cancer cases involving a misread mammogram:
- Radiologists who fail to detect or report suspicious findings on imaging.
- Hospitals and imaging centers – including facilities across New York from Manhattan to Staten Island – that employ negligent staff or maintain poor quality-control protocols.
- Referring physicians – when a doctor fails to order a mammogram when indicated, ignores abnormal test results, or fails to inform the patient.
- Third-party teleradiology providers and, rarely, equipment manufacturers whose technical failures contribute to errors.
Evidence Used in Breast Cancer Misdiagnosis Claims
Successful medical malpractice cases depend on strong evidence:
- Original mammogram images and radiology reports showing how findings were interpreted
- Medical records documenting symptoms, clinical exams, and the treatment timeline
- Pathology reports from biopsies establishing the type, grade, and stage of breast cancer
- A second opinion from an independent breast specialist reviewing all prior imaging
- Expert testimony from board-certified radiologists and oncologists explaining how the standard of care was breached

Legal Options for Patients in New York After a Misread Mammogram
Patients in New York who are harmed by a misread mammogram may have grounds to file a medical malpractice lawsuit if the error resulted from a failure to meet the accepted standard of care and caused additional harm. If successful, they may recover compensation for medical expenses related to delayed diagnosis or unnecessary treatment, including the costs of surgery, chemotherapy, radiation therapy, follow-up care, and reasonably anticipated future medical needs.
Patients may also seek compensation for lost wages, reduced earning capacity, and employment benefits lost because of the delayed or incorrect diagnosis. In addition, New York law allows recovery for non-economic damages such as pain and suffering, emotional distress, and loss of enjoyment of life. The amount of compensation depends on the specific facts of each case, including the extent of the patient’s injuries and resulting losses.
At The Pagan Law Firm, our breast cancer misdiagnosis lawyers offer a free consultation and handle cases on a contingency fee basis, meaning clients generally do not pay attorneys’ fees unless compensation is recovered. A confidential case evaluation can help determine whether you may have a viable breast cancer misdiagnosis claim.
Statute of Limitations and Time Sensitivity in New York
New York imposes strict deadlines for filing medical malpractice lawsuits. In most cases, a claim must be filed within 2 years and 6 months (30 months) of the alleged malpractice or from the end of continuous treatment for the same condition. In cases involving the failure to diagnose cancer or a malignant tumor, Lavern’s Law provides a limited discovery rule. Under this law, a lawsuit may be filed within 2 years and 6 months from the date the patient knew or reasonably should have known of the alleged malpractice, but no later than 7 years after the alleged malpractice occurred.
If the claim involves a public hospital or another public health care entity, additional procedural requirements may apply, including serving a Notice of Claim within 90 days. Missing these deadlines can prevent you from pursuing compensation. Speaking with an experienced New York medical malpractice attorney as soon as possible can help preserve evidence and protect your legal rights.
What to Do If You Suspect Your Mammogram Was Misread
Discovering that you were diagnosed with breast cancer after a recent “normal” mammogram, or learning that you underwent unnecessary treatment following an incorrect cancer diagnosis, can be overwhelming. Although not every missed or incorrect diagnosis results from medical negligence, taking the following steps can help protect both your health and your legal rights.
- Request complete medical records. Obtain copies of your mammogram images, radiology reports, pathology reports, biopsy records (if applicable), and physician office notes in both digital and printed form.
- Seek a second opinion. An independent breast specialist or breast radiologist can review your prior imaging and medical records to determine whether suspicious findings may have been overlooked or misinterpreted.
- Document everything. Keep a detailed timeline of your symptoms, appointments, diagnostic tests, treatments, and communications with your healthcare providers.
- Consult a New York breast cancer misdiagnosis lawyer. At Pagan Law Firm, we offer a free case evaluation to determine whether medical negligence may have occurred and to explain your legal options.

Frequently Asked Questions
Does a bad outcome automatically mean my mammogram was misread?
No. A poor outcome does not, by itself, mean that a mammogram was misread or that medical malpractice occurred. Some breast cancers are aggressive, difficult to detect on imaging, or may develop between routine screenings despite appropriate care. Determining whether a radiologist failed to meet the accepted standard of care typically requires a detailed review of the original imaging, radiology reports, and related medical records by qualified medical experts. A medical malpractice attorney can help coordinate this type of review during an initial consultation.
Can I bring a claim if I was falsely told I had breast cancer?
Possibly. Patients who undergo unnecessary surgery, chemotherapy, radiation therapy, or other medical interventions after an incorrect cancer diagnosis may have grounds for a medical malpractice claim if the misdiagnosis resulted from a departure from the accepted standard of care. Potential damages may include medical expenses, lost income, physical complications, and emotional distress related to the incorrect diagnosis and treatment.
What if I signed consent forms for my breast cancer treatment – can I still sue?
Yes, in some cases. Informed consent forms explain known risks of a procedure but generally do not protect healthcare providers from liability for negligence in diagnosing or recommending treatment. If treatment was based on a negligently interpreted mammogram or other diagnostic error, signing a consent form does not necessarily prevent a medical malpractice claim. Medical records and consent documents should be reviewed carefully by an attorney to assess the situation.
How long does a breast cancer misdiagnosis lawsuit usually take in New York?
These cases are complex and often take 18 months to several years to resolve, depending on factors such as medical complexity, expert analysis, court scheduling, and whether the case settles before trial. Early stages typically involve obtaining medical records, expert review, and filing the complaint, followed by discovery, depositions, and settlement discussions. Early action can help preserve evidence and ensure compliance with filing deadlines.
Will I need to testify in court if I file a misread mammogram claim?
Many breast cancer misdiagnosis cases settle before trial. However, if a lawsuit is filed, you will likely need to participate in a deposition and may be required to testify if the case proceeds to trial. Your attorney will prepare you thoroughly for each stage of the process and explain what to expect during sworn testimony.
