Washington Cancer Misdiagnosis Attorney
Injury Law Group NW represents people across Washington whose cancer was missed, mislabeled, or found too late because a doctor, hospital, or lab fell short of the accepted standard of care, with clients throughout King County, the Eastside, Seattle, and the greater Puget Sound region. Our work in this area centers on patients and families who learned that a diagnosis could have been made months or years earlier, and who now face a harder treatment path than they should have.
A Washington cancer misdiagnosis attorney has to untangle a problem that most injury cases do not have: the harm is not a single event. It is a delay, and the damage is measured by what that delay allowed the disease to do. A tumor that was visible on an earlier scan, a biopsy read incorrectly, a lump dismissed without follow-up imaging, an abnormal lab value never acted on. In each, the legal question is the same. If the cancer had been identified when it should have been, would the outcome have been meaningfully better?
That question is rarely answered in a clinic or a settlement letter. It is answered with the medical records, the original imaging and pathology slides, and testimony from specialists who can explain what a timely diagnosis would have changed.
How a Delayed Cancer Diagnosis Becomes a Malpractice Claim
Doctors are not liable simply because a cancer was found late. Cancer is sometimes genuinely hard to detect, and symptoms can look like something benign. A Washington medical malpractice claim requires proof that the provider failed to act as a reasonably careful practitioner in the same specialty would have, and that this failure caused harm. Both pieces matter, and the second one is where many cancer cases are won or lost.
In practice, these cases tend to unfold in a recognizable order. Someone reports symptoms or has a screening result that deserves a closer look. The provider orders too little testing, misreads what comes back, or fails to communicate an abnormal finding. Weeks or months pass. When the cancer is finally identified, it has often advanced a stage or spread. The patient then starts treatment that is more aggressive, less likely to succeed, or both.
The claim is built backward from that moment. Our attorneys gather the full chart, identify the point at which a reasonable provider would have acted, and then work with qualified medical experts to compare the real trajectory with the one that earlier diagnosis would have produced. Stage at diagnosis, tumor type, treatment options that were lost, and survival odds all become evidence.
Where Cancer Misdiagnosis Claims Come From
- Misread imaging: Radiologists reviewing mammograms, chest X-rays, CT scans, and MRIs can overlook a mass or nodule that was present and visible, or describe it in a report so vaguely that no follow-up is triggered.
- Pathology and lab errors: A biopsy slide read as benign when it was malignant, a specimen mixed up with another patient’s, or a test never run at all can send a patient home reassured when they should be in treatment.
- Dismissed symptoms: Persistent pain, unexplained weight loss, abnormal bleeding, or a lump that is attributed to stress, age, or a minor condition without a workup that would have ruled out cancer.
- Failure to follow up on abnormal results: Test results that come back flagged but are never relayed to the patient or acted on by the ordering physician, often because of poor handoffs between a primary care office and a specialist.
- Missed screening recommendations: Colonoscopy, mammogram, Pap, and other age- or risk-based screenings that a provider should have recommended, especially for patients with a family history or known risk factors.
- Wrong cancer type or stage: A diagnosis that identifies a cancer but misclassifies it, leading to the wrong treatment plan, unnecessary surgery, or chemotherapy that does not match the actual disease.
- Emergency department and urgent care misses: Rushed evaluations where warning signs of a serious condition are not escalated to a specialist or advanced imaging.
Why Choose Injury Law Group NW for a Cancer Misdiagnosis Claim
Injury Law Group NW is a personal injury firm that serves clients throughout King County, the Eastside, Seattle, and across Washington. Our attorneys spent decades defending insurance companies before changing sides, and that history matters in medical malpractice, where hospital systems and their insurers defend aggressively and value claims with practiced precision. Free, confidential consultations are available, and we take injury cases on a contingency fee basis, so you owe no attorney fee unless we recover money for you.
Troy Hunter, our founding partner, spent 16 years in insurance defense litigation, mostly as a partner at Floyd, Pflueger & Ringer, defending insurers and corporate clients against personal injury and wrongful death claims. David D. Mordekhov spent two decades at Gardner Trabolsi & Mordekhov trying wrongful death, catastrophic injury, and product liability cases to judges and juries. Both are rated AV Preeminent by Martindale-Hubbell. David has been selected to the Super Lawyers list and teaches trial and deposition skills as faculty at the National Institute for Trial Advocacy. Troy also serves as a dispute mediator. Associate attorneys Warren Barreiro and Hannah Shergold are part of the team, and the firm is a member of the Washington State Association for Justice. Our attorneys have argued at every level of the Washington court system, from district court to the Washington Supreme Court.
We know how a malpractice insurer evaluates a delayed-diagnosis claim: which records they pull first, how they argue that the outcome would have been the same regardless, and when they are preparing to settle versus preparing to fight. We prepare every claim as though it will be tried, because insurers pay more fairly when they believe the lawyer across the table will go to court.
Our results reflect that approach. We recovered more than $1 million for parents whose newborn died after a hospital failed to adequately test for Group B Strep, a case that also led the hospital to change its procedures. Every case is different, and past results do not guarantee a future outcome. Clients consistently describe our team as responsive, communicative, and honest, and our case managers return calls and texts promptly. David Mordekhov is fluent in Russian and Warren Barreiro speaks Spanish. If illness makes travel difficult, we will meet you at home or at the hospital. Our motto is “We give hope. We get results.”
What to Do If You Think Your Cancer Was Missed
Start by getting the care you need. If a new diagnosis has just been made, your first priority is a treatment plan with an oncology team you trust, and nothing about a legal claim should slow that down. Many patients seek a second opinion at a different hospital system, which also has the practical benefit of producing an independent read of earlier imaging or pathology.
Next, request your complete medical records, not just visit summaries. You want the actual imaging studies and radiology reports, pathology reports, lab results, referral notes, and any messages or portal communications. Original slides and images can be requested and independently reviewed, which is often where a missed finding becomes obvious. Keep a simple timeline of when symptoms began, what you reported, who you saw, and what you were told. Dates matter, and memory fades quickly during treatment.
Do not sign a release or accept an explanation from the hospital’s risk management office without speaking to a lawyer. Do not give a recorded statement to any insurer. And pay attention to deadlines. Washington generally requires a malpractice action to be started within three years of the negligent act or omission, or within one year of when you discovered, or reasonably should have discovered, that the care caused your injury, whichever expires later. Cancer cases often turn on that discovery rule, because patients do not know about a missed finding until a later diagnosis. The statute also contains an outer time limit, and the Washington Supreme Court has addressed its constitutionality, so that limit should be confirmed with an attorney rather than assumed. A narrow exception can extend the deadline when a provider committed fraud or intentionally concealed what happened.
If the care came from a public hospital or a government-run clinic, a different process applies. Claims against the state require a formal claim form presented to the Office of Risk Management, and claims against a county, city, or other local entity must be presented to that entity’s designated claims agent. In both situations, a lawsuit cannot be filed until 60 calendar days have passed after the claim is presented, and the limitations period is paused during that window. Missing this step can end a valid case, so it is worth raising early.
Cases in this area are usually filed in King County Superior Court, a general jurisdiction trial court that sits in Seattle and in Kent. Cancer misdiagnosis claims involve serious injury and large damages, so they belong in superior court rather than the district courts, which handle claims up to a set dollar limit. A federal court in Seattle may become involved in unusual circumstances, such as certain claims involving federal facilities.
Proving That the Delay Changed the Outcome
This is the heart of a delayed cancer diagnosis case, and it is where careful preparation separates a strong claim from a weak one. Defense lawyers often concede that a mistake happened and then argue it made no difference: the cancer was aggressive anyway, or treatment would have been the same. Rebutting that requires specific medical evidence.
Oncologists and other specialists can testify about how the cancer behaves at different stages, what treatments are available earlier but not later, and how survival and recurrence rates differ. In some cases the proof is straightforward, such as a tumor that was localized and curable when first visible and metastatic when finally found. In others, the evidence involves growth rate modeling and imaging comparisons. Washington applies pure comparative fault, so if a patient missed appointments or ignored a recommended test, that may reduce the recovery proportionally but does not bar it.
Damages can include the cost of additional and more intensive treatment, lost income and earning capacity, and the pain, fear, and disruption that came with a harder illness. When a patient dies, Washington allows the personal representative to bring a wrongful death claim for the benefit of the spouse, registered domestic partner, and children, or, if none exist, parents or siblings. The estate may also pursue the survival claim for the decedent’s own losses. The three-year period for a wrongful death claim runs from the date of death.
Questions About Cancer Misdiagnosis Claims in Washington
What counts as cancer misdiagnosis versus a delayed diagnosis?
Misdiagnosis usually means a provider concluded you had something other than cancer, or identified the wrong type of cancer. Delayed diagnosis means the cancer was eventually found but later than a reasonably careful provider would have found it. Washington law treats both as potential medical negligence, and many cases involve elements of each.
How long do I have to file a cancer misdiagnosis lawsuit in Washington?
Generally three years from the negligent act or omission, or one year from when you discovered or reasonably should have discovered that the care caused your injury, whichever is later. Claims against public entities require a prior claim and a 60-day waiting period. Because these rules interact, speak with a lawyer as soon as you suspect a problem.
Can I bring a claim if my cancer was already advanced when it was finally found?
Possibly. The question is whether earlier diagnosis would have improved your outcome, even if the cancer was serious regardless. Lost treatment options, reduced survival odds, and a harder course of therapy can all support a claim.
Do I need a medical expert for this type of case?
Yes. Proving the standard of care and causation requires qualified medical testimony. We work with experts in radiology, pathology, oncology, and other relevant specialties to evaluate what happened before we commit to a claim.
What if the misdiagnosis happened at a hospital but I was treated by several doctors?
Responsibility may be shared among individual physicians, the hospital, a radiology group, or a lab. Identifying every responsible party matters, because each may carry separate insurance, and naming only one can leave recovery on the table.
What if a family member died after a missed cancer diagnosis?
Washington allows a wrongful death claim through the personal representative of the estate, for the benefit of the surviving spouse or registered domestic partner and children, or parents or siblings if there are none. The estate can also seek the economic losses, and in some circumstances the decedent’s own suffering. The deadline generally runs three years from the date of death.
Will my health insurance cover treatment while my claim is pending?
Your health insurance should continue to cover treatment, and you should not delay care to wait on a claim. Insurers may later seek reimbursement from any recovery, so we track those liens and work to keep them from consuming your settlement.
Can I sue if my doctor ordered a test and the lab lost or mishandled it?
Yes, a lab error can support a claim against the lab, and the ordering physician may also be responsible for failing to notice that results never arrived. Missing results are a common thread in delayed-diagnosis cases.
What if I waited to seek a second opinion and lost time?
Washington reduces recovery by the percentage of fault assigned to the patient but does not bar it. A patient who relied on a doctor’s reassurance is generally in a different position than one who ignored clear instructions, and the facts of what you were told matter.
How long does a cancer misdiagnosis case usually take?
These cases take longer than most injury claims because of the expert review, record gathering, and depositions involved. Many take well over a year, and cases that go to trial take longer. We keep clients informed at each stage so there are no surprises.
Is it worth pursuing a claim if I am already recovering well?
It can be. Even a good outcome may have required extra surgery, longer treatment, or lost income that earlier diagnosis would have avoided. A consultation can help you judge whether the losses justify a claim.
