Delayed Diagnosis, False Positives, and Pathology Errors

At Lupetin & Unatin, we’ve spent decades fighting for patients whose cancer was missed until it was nearly too late. We’ve handled, settled, or tried to verdict cases involving misread biopsies and screening failures across PA. If a delayed diagnosis took away your best chance at a cure, Pennsylvania law may entitle you to compensation.

Do I Have a Medical Malpractice Case?

A cancer misdiagnosis is one of the most devastating forms of medical negligence, often turning a treatable condition into a terminal one. In cancer cases, malpractice occurs when a doctor’s failure to follow the Standard of Care results in a measurable delay in treatment or an incorrect, life-altering procedure. Whether it was a failure to screen, a misread biopsy, or a false positive that led to unnecessary surgery, Pennsylvania law provides a path for justice and our attorneys are ready to help you.

Four Requirements for a Medical Malpractice Claim

  • Duty of Care: A doctor-patient relationship existed during the screening or diagnostic process.
  • Breach of Standard: The provider ignored “red flag” symptoms or failed to order standard tests (like a mammogram or colonoscopy) that a competent peer would have.
  • Causation (Loss of Chance): In Pennsylvania, we prove that the delay caused an “Increased Risk of Harm,” meaning your chances of survival or a successful recovery were measurably reduced.
  • Damages: The error led to more invasive treatments, shortened life expectancy, lost wages, or wrongful death.

Cancer Misdiagnosis “Red Flags” Checklist

  • The “Watch and Wait” Error: You presented with a lump or persistent symptom, but the doctor dismissed it as a “cyst” or “infection” without ordering a biopsy or scan.
  • The Silent Test Result: You underwent a screening (like a PAP smear or PSA test), but were never notified of an abnormal finding that required follow-up.
  • The Pathology Mix-Up: You were told you had cancer and underwent aggressive treatment, only to later discover the biopsy slides were contaminated or mislabeled.
  • Rapid Progression: A cancer that was supposedly “nothing to worry about” six months ago is suddenly diagnosed as Stage 3 or Stage 4.

Commonly Occurring Cancer Misdiagnosis Errors

Delayed Diagnosis of Breast Cancer

Negligence typically occurs when a radiologist misinterprets a mammogram as “normal” despite visible calcifications, or when a physician fails to order a diagnostic ultrasound for a palpable lump. In Pennsylvania, we focus on proving that these oversights allowed the cancer to spread to the lymph nodes, requiring more aggressive chemotherapy or a mastectomy that could have been avoided with a timely Stage 1 diagnosis.

Colorectal Cancer & Screening Failures

Malpractice occurs when a primary care doctor fails to recommend a colonoscopy based on age or family history, or when a gastroenterologist fails to identify a suspicious polyp during the procedure. Our firm is dedicated to helping families who were lulled into a false sense of security by a “clear” report, only to be diagnosed with advanced colon cancer a year later because the initial screening was performed negligently.

Lung Cancer & Misread Imaging

Negligence arises when a radiologist fails to recommend a follow-up CT scan for an “incidental finding” or when a physician ignores a persistent cough in a non-smoker. In Pennsylvania, we use the “Increased Risk of Harm” standard to hold providers accountable for missing the narrow window where lung cancer can be surgically removed before it metastasizes to the brain or bones.

Skin Cancer & Melanoma Biopsy Errors

Malpractice typically involves a dermatologist failing to biopsy a changing mole or a pathologist misinterpreting a malignant melanoma as a benign “nevus.” Because melanoma spreads rapidly through the bloodstream, we investigate the diagnostic timeline to prove that the provider’s failure to recognize “red flag” characteristics (asymmetry, borders, color) directly led to a terminal prognosis.

Pathology Errors & False Positives

As seen in recent landmark Pennsylvania verdicts (such as the $35 million Isis Spencer case in 2026), pathology errors often involve contaminated biopsy slides or mislabeled specimens. Our firm focuses on cases where clinicians proceed with life-altering surgeries—like a hysterectomy or mastectomy—without reconciling conflicting test results or pursuing necessary verification steps.

Prostate Cancer & PSA Monitoring

Negligence occurs when a doctor fails to track a “PSA velocity” (the rate of change) or fails to refer a patient to a urologist for a biopsy when levels become suspicious. We hold providers accountable for ignoring established screening guidelines, ensuring that patients are not deprived of the opportunity for localized treatment that preserves their quality of life.

Pennsylvania Legal Rules & Deadlines

In Pennsylvania, you generally have two years from the date of the error to file a claim. However, cancer misdiagnosis cases are unique because the error is often discovered years later.

The Discovery Rule: The two-year “clock” may not start until the date you first “reasonably” realized that your cancer should have been caught earlier. If you were told your 2024 mammogram was “clear” but were diagnosed with Stage 3 cancer in 2026, your window for a claim likely begins at the 2026 diagnosis.

On February 18, 2026, the Pennsylvania Supreme Court issued an order confirming that expanded venue rules are now permanent.

Filing Advantage: We are no longer restricted to suing in the county where the misdiagnosis occurred. If the hospital system (such as UPMC or AHN) “regularly conducts business” in Pittsburgh, we can often file your case in Allegheny County. This is a major advantage for victims seeking a jury pool familiar with the high standards of major metropolitan medical centers.

Pennsylvania’s Medical Care Availability and Reduction of Error (MCARE) Act ensures that funds are available for significant cancer-related settlements. Under MCARE, doctors carry primary insurance, but the state-mandated fund provides an additional layer of “excess” coverage. For families facing the loss of a primary earner or immense future medical costs, MCARE provides the financial security necessary to cover a multi-million dollar verdict or settlement.

Within 60 days of filing a cancer misdiagnosis lawsuit, Pennsylvania law requires a Certificate of Merit. This is a formal statement from your attorney confirming that a qualified expert—such as a board-certified oncologist or pathologist—has reviewed your records and believes the care fell below professional standards. Our firm handles the complex task of securing these expert reviews to ensure your case is medically supported from the start.

Delayed diagnosis of colorectal cancer is not always an unavoidable tragedy. In many cases it is the direct result of a physician’s failure to screen appropriately, to recognize the warning signs, to follow up an abnormal test result, or to refer a patient for specialist evaluation. We know how to determine whether your right to reasonable medical care was violated.

Frequently Asked Questions

Yes, potentially. The question is not what stage the cancer was at the end, but what stage it could have been if the doctor had acted sooner. If a doctor missed your cancer when it was Stage 1 or 2, and that delay allowed it to reach Stage 4, you have a claim for “Increased Risk of Harm.” We use oncology experts to recreate the timeline of how the cancer grew during the period of negligence.

This is a serious form of medical malpractice. If a lab error or misread biopsy led you to undergo an unnecessary hysterectomy, mastectomy, or chemotherapy, you are entitled to damages for the physical trauma and emotional distress. Recent 2026 verdicts in Pennsylvania have awarded tens of millions of dollars in cases where doctors failed to reconcile conflicting pathology reports before performing irreversible surgery.

Yes. It is the doctor’s professional duty to recommend screenings (like colonoscopies or mammograms) based on standard medical guidelines and your specific risk factors. You are not expected to be a medical expert. If a doctor fails to offer a routine screening and you later develop advanced cancer that could have been prevented, they have breached the Standard of Care.

We work with “Causation” experts who use statistical data and medical literature to show how the delay affected your survival rate. For example, if a 6-month delay in diagnosing breast cancer reduced your 5-year survival probability from 95% to 60%, we pursue damages for that 35% “Loss of Chance.
