Why Lavern's Law Exists: The Story Behind the Law
Lavern's Law — New York's discovery rule for medical malpractice — was named after Lavern Wilkinson, a 41-year-old Brooklyn woman who died in 2013 from a curable cancer.
Lavern visited a Brooklyn hospital in 2010 with chest pain. A chest X-ray revealed a mass, but the hospital never told her. Two years later, the cancer had spread to her liver, lymph nodes, and brain. By the time it was diagnosed, it was terminal. Lavern died on March 7, 2013, leaving behind a 15-year-old daughter with autism and a 19-year-old son.
Under New York's law at the time, the statute of limitations had expired because it ran from the date of the malpractice — not the date of discovery. Lavern didn't know she had been misdiagnosed until it was too late to sue.
The New York Legislature passed Lavern's Law to address this injustice. Under the amended CPLR 214-a, the statute of limitations in cases involving cancer may begin when the patient discovers (or reasonably should have discovered) the malpractice — rather than when it occurred.
Lavern's Law is particularly relevant to delayed breast cancer diagnosis cases, where the patient may not learn of the diagnostic error until months or years later.

How Breast Cancer Diagnosis Is Delayed
Breast cancer diagnosis involves multiple steps, and delays can occur at each stage:
1. Screening Mammography
A screening mammogram is an X-ray of the breast used to detect cancer in asymptomatic women. If the radiologist misses a tumor on a screening mammogram — or misclassifies it as benign — the diagnosis may be delayed by months or years.
2. Diagnostic Mammography
A diagnostic mammogram is performed when a patient has symptoms (such as a lump, pain, or nipple discharge) or when a screening mammogram shows an abnormality. Additional views and magnification are used. Errors here can delay diagnosis.
3. Ultrasound
Breast ultrasound is used to evaluate abnormalities found on mammography or physical examination. It can distinguish between solid masses (which may be cancer) and cysts (which are usually benign). Misinterpretation can lead to missed cancer.
4. MRI
Breast MRI is used for high-risk patients or to evaluate the extent of known cancer. It is more sensitive than mammography but also more prone to false positives. Misinterpretation can lead to errors.
5. Biopsy
A biopsy — removal of tissue for pathological examination — is the definitive test for breast cancer. Types include:
- Fine needle aspiration (FNA) — Uses a thin needle to extract cells
- Core needle biopsy — Uses a larger needle to extract a tissue core
- Surgical (excisional) biopsy — Removes the entire lump
Errors in biopsy technique, tissue processing, or pathology interpretation can lead to missed cancer.
6. Pathology
The pathologist examines the biopsy tissue under a microscope and determines whether cancer is present. This is the gold standard for diagnosis. Pathology errors — particularly false negatives — are among the most dangerous diagnostic errors in medicine.
Missed Mammograms: Radiology Errors
Mammography is the primary screening tool for breast cancer, but it is not perfect. Studies have shown that approximately 10-20% of breast cancers are missed on screening mammography. However, some of these misses constitute negligence when they involve:
1. Failure to Identify a Visible Mass
If a tumor is visible on the mammogram but the radiologist fails to identify it, this may be negligence. An independent radiologist can re-review the mammogram to determine whether the tumor should have been seen.
2. Misclassification of a Suspicious Finding
The BI-RADS (Breast Imaging Reporting and Data System) classification system is used to categorize mammographic findings:
- BI-RADS 0 — Incomplete; additional imaging needed
- BI-RADS 1 — Negative
- BI-RADS 2 — Benign finding
- BI-RADS 3 — Probably benign; short-interval follow-up
- BI-RADS 4 — Suspicious; biopsy should be considered
- BI-RADS 5 — Highly suggestive of malignancy; biopsy recommended
- BI-RADS 6 — Known biopsy-proven malignancy
If a radiologist classifies a BI-RADS 4 or 5 lesion as BI-RADS 2 or 3, the patient may not receive a biopsy, and the cancer may go undiagnosed.
3. Failure to Compare with Prior Studies
The standard of care requires comparing current mammograms with prior mammograms to detect changes. A new mass, growing mass, or developing calcifications may indicate cancer. Failure to compare may be negligence.
4. Failure to Recommend Additional Imaging or Biopsy
If the mammogram shows an abnormality that requires additional imaging (such as spot compression views, ultrasound, or MRI) or biopsy, and the radiologist fails to recommend it, the diagnosis may be delayed.

Pathology Errors: Misread Biopsies
Pathology errors in breast cancer diagnosis can be devastating. A false negative — a biopsy that is reported as benign when cancer is actually present — gives false reassurance and allows cancer to grow untreated.
Types of Pathology Errors
- False negative — Missing cancer that is present on the biopsy
- False positive — Diagnosing cancer when it is not present (leading to unnecessary surgery, chemotherapy, and radiation)
- Misclassification — Identifying the wrong type of cancer (e.g., ductal vs. lobular carcinoma)
- Grading errors — Assessing the aggressiveness (grade) of the cancer incorrectly
- Margin assessment errors — Incorrectly reporting whether the surgical margins are clear
- Receptor testing errors — Misidentifying estrogen receptor (ER), progesterone receptor (PR), or HER2 status, which guides treatment
The Standard of Care for Breast Pathology
The standard of care requires:
- Adequate sampling — The biopsy must include sufficient tissue
- Proper processing — Fixation, embedding, sectioning, and staining
- Expert interpretation — The pathologist should have expertise in breast pathology
- Second opinion — For difficult or borderline cases, a second pathology opinion may be indicated
[Link to: /medical-malpractice/pathology-errors]
Failure to Follow Up on Abnormal Results
One of the most common and dangerous errors is the failure to follow up on abnormal results. This can occur when:
- The patient is not notified — Of an abnormal mammogram, biopsy, or lab result
- A referral is not made — To a surgeon or oncologist when indicated
- A biopsy is not scheduled — After an abnormal mammogram
- Results are lost — In the communication chain between radiology, pathology, and the treating physician
- The patient "falls through the cracks" — In a large healthcare system
The standard of care requires a systematic approach to tracking and following up on abnormal results. Failure to have or follow such a system may be negligence by both the individual provider and the institution.
Inadequate Physical Examination
The clinical breast examination (CBE) — a physical examination of the breasts by a physician — remains an important component of breast cancer screening. Failure to perform an adequate CBE — or failure to follow up on a palpable mass — can delay diagnosis.
The standard of care for a patient with a palpable breast mass includes:
- Diagnostic mammography (not just screening)
- Ultrasound — To evaluate the mass
- Biopsy — If the mass is suspicious, even if imaging is negative
- Referral to a surgeon — For evaluation
A common and dangerous error is attributing a palpable mass to a cyst or fibroadenoma without appropriate evaluation — including biopsy of any suspicious or persistent mass.
The Impact of Delayed Breast Cancer Diagnosis
Staging and Survival
Breast cancer survival is strongly correlated with stage at diagnosis:
| Stage | Description | 5-Year Survival Rate | |-------|-------------|---------------------| | Stage 0 | Ductal carcinoma in situ (DCIS) | ~100% | | Stage I | Small tumor, no lymph node involvement | ~99% | | Stage II | Larger tumor or limited lymph node involvement | ~86% | | Stage III | Larger tumor or extensive lymph node involvement | ~57% | | Stage IV | Metastatic (spread to distant organs) | ~29% |
A delay of months can allow cancer to progress from a highly curable early stage (Stage I) to a less curable advanced stage (Stage III or IV). This is why delayed diagnosis is so devastating — a delay of 6-12 months can be the difference between life and death.
Additional Consequences
- More aggressive treatment — Later-stage cancer requires more aggressive surgery, chemotherapy, and radiation
- Loss of breast — A lumpectomy that would have been possible at an early stage may need to be a mastectomy at a later stage
- Chemotherapy — That could have been avoided with earlier diagnosis
- Metastasis — Cancer spreading to bones, liver, lungs, or brain
- Death — From metastatic disease
Proving Causation in Breast Cancer Cases
In a delayed breast cancer diagnosis case, the plaintiff must prove that the delay caused additional harm. This requires:
The "Loss of Chance" Doctrine
New York recognizes the loss of chance doctrine, which allows recovery when the physician's negligence reduced the patient's chance of survival — even if the prognosis was already poor.
For example, if a 6-month delay reduced the patient's chance of survival from 60% to 30%, the patient may recover damages for the lost chance — the 30% reduction in survival probability.

Expert Testimony
Breast cancer cases require testimony from:
- A radiologist — On the standard of care for mammography
- A pathologist — On the standard of care for biopsy interpretation
- A breast surgeon — On the impact of delay on treatment options
- An oncologist — On the impact of delay on survival
- A biostatistician — On the reduction in survival probability
Key Evidence
- Mammograms and imaging — Can be re-reviewed by an independent radiologist
- Pathology slides — Can be re-reviewed by an independent pathologist
- Medical records — Documenting the evaluation, communication, and follow-up
- EMR audit trail — Showing who accessed or modified records
Lavern's Law: The Discovery Rule
Under Lavern's Law (CPLR 214-a, as amended), the statute of limitations for medical malpractice involving cancer may begin when the patient discovers (or reasonably should have discovered) the malpractice.
This is critical for delayed breast cancer diagnosis cases, where the patient may not learn that:
- A mammogram was misread
- A biopsy was misinterpreted
- An abnormal result was not communicated
...until months or years after the malpractice occurred.
Important Limitations
Lavern's Law is not unlimited. There are outer time limits that apply, and the discovery must be of both the injury and its negligent cause. An experienced attorney is essential to determine whether your claim is timely.
The Loss of Chance Doctrine
The loss of chance doctrine is particularly important in breast cancer cases, where the patient may have had a good prognosis with timely diagnosis but a poor prognosis after the delay.
How It Works
If the physician's negligence reduced the patient's chance of survival from 75% to 40%, the patient can recover damages proportional to the lost chance — the 35% reduction in survival probability.
Mathematical Analysis
New York courts use expert testimony and biostatistical analysis to calculate the reduction in survival probability. This requires:
- Survival data — For the cancer type and stage at the time of the missed diagnosis
- Survival data — For the cancer type and stage at the time of actual diagnosis
- The difference — Represents the lost chance
Statute of Limitations
Under CPLR 214-a, the statute of limitations is 2.5 years from the date of the malpractice. Under Lavern's Law, the clock may start when the patient discovered (or should have discovered) the malpractice — particularly important in cancer cases.
Frequently Asked Questions
Can I sue for delayed breast cancer diagnosis?
Yes. If a radiologist, pathologist, or physician failed to diagnose your breast cancer — by misreading a mammogram, misinterpreting a biopsy, or failing to follow up on abnormal results — and the delay caused additional harm, you may have a malpractice claim.
What is Lavern's Law?
Lavern's Law is New York's discovery rule for medical malpractice. It allows the statute of limitations to begin when the patient discovers (or should have discovered) the malpractice — rather than when it occurred. This is particularly important in cancer cases where the patient may not learn of the error for months or years.
What is the loss of chance doctrine?
The loss of chance doctrine allows recovery when a physician's negligence reduced the patient's chance of survival — even if the prognosis was already poor. The patient recovers damages proportional to the reduction in survival probability.
Can my mammogram be re-reviewed?
Yes. Your attorney can obtain your mammogram images and have them re-reviewed by an independent radiologist to determine whether cancer should have been detected.
Can my pathology slides be re-reviewed?
Yes. Your attorney can request that pathology slides be preserved and produced for independent review by a qualified pathologist. This is one of the most important steps in a delayed breast cancer diagnosis case.
How long do I have to file a claim?
Under CPLR 214-a, the deadline is generally 2.5 years from the date of the malpractice. Under Lavern's Law, the clock may start when you discovered (or should have discovered) the malpractice.
