Compensation Claim Due to Delayed Diagnosis or Wrongful Treatment in Cancer Treatment

What are late diagnosis or incorrect treatment in cancer therapy?

In cancer treatment, delayed diagnosis or incorrect treatment refers to harm to the patient due to a delay in diagnosis, incorrect staging of the disease, or failure to administer appropriate treatment in a timely manner, because the patient's complaints, examination findings, laboratory results, imaging records, biopsy or pathology reports are not evaluated correctly and in a timely manner.

In cancer treatment, time is of the essence. Failure to promptly assess a mass, suspicious lesion, bleeding, imaging abnormality, or pathology result can lead to disease progression, loss of surgical options, the need for more aggressive chemotherapy or radiotherapy, organ loss, decreased quality of life, or a shortened lifespan.

However, late detection of every cancer does not automatically mean medical malpractice. Some cancers can progress without symptoms, some tumors may not be detectable by imaging in the early stages, and some biopsies may initially contain limited samples. The key issue for legal liability is whether the necessary assessments, which a diligent physician or healthcare facility should have made under the same circumstances, were carried out.

For example, liability for compensation may arise if a patient is discharged with a "minor" diagnosis despite having long-standing bleeding, weight loss, persistent cough, breast lump, skin changes, difficulty swallowing, unexplained pain, or abnormal test results; if a suspicious finding in a radiology report is not followed up; if a biopsy is delayed; if a pathology report is misinterpreted; if treatment is unnecessarily delayed; or if an incorrect treatment protocol is applied.

The Obligation of Early Diagnosis and the Importance of Cancer Screenings

In cancer screening programs, the responsibility for early detection is a crucial area of ​​evaluation for both physicians and healthcare institutions. The Ministry of Health's cancer screening programs include regular screenings for breast, cervical, and colorectal cancers within specific age and risk groups; for example, cervical cancer screening involves HPV-DNA testing at regular intervals for women aged 30-65, while colorectal cancer screening programs target the 50-70 age group.

These screening programs demonstrate the medical importance of early cancer detection. The "early diagnosis saves lives" approach is not just a public health slogan; it also requires that suspicious findings be taken seriously in medical practice, risk groups be monitored, and necessary examinations be carried out in a timely manner. The fact that the Ministry of Health's KETEM (Cancer Early Detection and Screening Center) and screening programs include specific screening standards for breast, cervical, and colorectal cancers is a concrete indication of this obligation.

Of course, doctors are not expected to diagnose cancer in every patient. However, if there are clear warning signs, it can create legal problems if the doctor dismisses these findings as simple illnesses and completely rules out further investigation. For example, if blood in the stool is dismissed as hemorrhoids for a long time; if a mammogram/ultrasound or biopsy is not performed despite a breast mass; if a nodule on a chest X-ray is not followed up; or if a patient with HPV or smear abnormalities is not referred, then the claim of delayed diagnosis arises.

The Most Common Causes of Late Cancer Diagnosis

Late diagnosis of cancer can stem from various stages. The primary reason is that the patient's symptoms are not taken seriously enough. Symptoms such as unexplained weight loss, persistent fatigue, prolonged fever, persistent cough, bleeding, breast lumps, changes in bowel habits, skin lesions, difficulty swallowing, blood in the urine, or prolonged pain should be evaluated.

The second reason is insufficient testing. The physician should order laboratory tests, ultrasound, mammography, CT scan, MRI, endoscopy, colonoscopy, biopsy, or consultation with a relevant specialist, depending on the patient's age, risk factors, and symptoms. Sending a patient away with symptomatic treatment repeatedly without performing the necessary tests can lead to delayed diagnosis.

The third reason is errors in radiology or pathology reports. Imaging and pathology are crucial in cancer diagnosis. A chain of responsibility can be created if suspicious findings are seen in mammography, chest X-rays, CT scans, MRIs, PET-CT scans, or ultrasounds but not mentioned in the report; if the pathology result is falsely negative; if a biopsy sample is insufficient but a repeat sample is not taken; or if a suspicious statement in the report is not followed up by the clinical physician.

The fourth reason is a lack of system and organization. The patient's results may be ready but not communicated to them. The report may have been uploaded to the system but not seen by the doctor. The pathology result may indicate a suspicion of cancer, but the patient may not have been called in for a follow-up. In such cases, not only individual physician error but also organizational shortcomings of the hospital come into play.

Late Diagnosis of Cancer Due to Radiology Error

Radiology reports are crucial evidence in cancer diagnosis. Imaging methods such as mammography, ultrasound, CT scan, MRI, and PET-CT are used in the early detection of cancer. However, if a suspicious mass, nodule, lesion, lymph node, or metastasis present in the image is not included in the report, the patient may remain untreated for months or years due to a false sense of security.

For example, a nodule might be seen on a lung CT scan but reported as "normal," and the patient might be diagnosed with advanced lung cancer a year later. A suspicious mass might not be detected on a mammogram, and breast cancer may have metastasized. A tumor might be missed on a brain MRI, and the patient may have suffered neurological losses. In such cases, old images should be re-examined. Not only the old report, but the image itself should be sent to the expert panel.

In cases of radiology errors, responsibility may not lie solely with the radiologist. The clinician who requested the report should also evaluate the patient's complaints and the report's findings. If the report contains phrases such as "follow-up recommended," "suspicious lesion," or "further investigation required," the physician must follow this recommendation. The clinician and the hospital may also be held responsible if the patient is not called for a follow-up or additional tests are not performed.

Pathology and Biopsy Errors

In cancer diagnosis, the pathology report is often the decisive document. A biopsy sample is examined in a pathology laboratory, and the report details the presence of cancer, its type, grade, hormone receptors, genetic/molecular characteristics, or other findings that determine treatment. Pathology errors can occur in the form of false negatives, incorrect cancer types, incomplete assessment affecting staging, or sample mix-ups.

If the biopsy sample is insufficient, a repeat biopsy may be necessary. However, if the patient is initially diagnosed with cancer after being declared "clear," the pathology report and clinical follow-up are reviewed together. This is because the pathology report may contain phrases such as "insufficient material," "clinical/radiological correlation recommended," "suspicious findings," or "a repeat biopsy would be appropriate.".

In cases of errors in pathology reports, the laboratory's authentication system, sample acceptance records, block and slide archives, immunohistochemistry results, second pathology opinion, and whether samples have been mixed up should be examined. Re-evaluating pathology material in cancer cases often changes the course of the case.

What is Treatment Error in Cancer Therapy?

In cancer, incorrect treatment is not limited to delayed diagnosis. Even after diagnosis, harm can occur due to incorrect staging, wrong surgical decisions, unnecessary surgeries, chemotherapy protocol errors, radiotherapy planning errors, drug dosage errors, incorrect application of targeted therapy, inability to manage side effects, or delayed initiation of treatment.

Cancer treatment is a multidisciplinary process. Oncology, surgery, radiology, pathology, radiation oncology, nuclear medicine, genetics, intensive care, and supportive care units may work together. Therefore, treatment decisions should be made considering the patient's cancer type, stage, age, general condition, comorbidities, pathological characteristics, and scientific guidelines.

For example, liability for compensation arises if a patient in a surgically treatable stage of the disease is unnecessarily delayed and the tumor progresses; if the chemotherapy dose is not adjusted according to the patient's kidney and liver function; if treatment continues unchanged despite reports of drug allergies or severe side effects; if the wrong area is irradiated during radiotherapy; or if the cancer stage is incorrectly determined, resulting in insufficient treatment.

Delayed Treatment and Loss of Treatment Opportunity

One of the most important concepts in cancer cases is "loss of chance for treatment." In some cases, diagnosis or treatment is delayed even when cancer is at a completely curable stage; the patient is diagnosed at a more advanced stage. This delay can affect the patient's chances of having surgery, receiving less severe treatment, their lifespan, or their quality of life.

Legally, not every delay is grounds for compensation. The delay must have medically altered the course of the disease. For example, a three-day delay may not affect the outcome in some types of cancer; however, months of lack of follow-up or biopsy delay could alter the stage of the disease. Therefore, the expert witness must evaluate the impact of the delay on the stage of the cancer, treatment options, and prognosis.

It may not always be possible to prove that a patient would have recovered if the opportunity for treatment was lost. However, if the possibility of a better lifespan, less invasive treatment, or organ-preserving treatment existed with early diagnosis or appropriate treatment, and this possibility was negligently eliminated, then compensation may be considered.

Informed Consent and Cancer Patient Education

Cancer patients should be clearly informed about their diagnosis, the stage of their disease, the treatments to be applied, the risks of the treatments, alternatives, the consequences of refusing treatment, and the course of the disease. The Patient Rights Regulation stipulates that patients have the right to request verbal or written information about their health condition, the medical procedures to be performed, their benefits and possible drawbacks, alternative methods, the consequences of refusing treatment, and the course of their disease.

Informed consent is particularly important in cancer treatment because surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapies, hormonal therapy, or palliative care can have serious side effects. The patient should be informed about the goal of the treatment, whether it is curative or disease-controlling, the expected benefits, side effects, likelihood of success, and alternative treatment options.

Informed consent is not simply about having a form signed. It's not enough to tell the patient, "You will receive chemotherapy." The side effects of the medications, the risk of infection, hair loss, nausea, decreased blood counts, organ toxicity, effects on fertility, side effects of radiotherapy, the scope of the surgery, and possible complications must be explained to the patient in a way they can understand.

The Importance of Medical Records

In cancer cases involving delayed diagnosis or malpractice, medical records are fundamental to the case. The Patient Rights Regulation stipulates that patients can directly review and obtain copies of files and records related to their health status, either through their legal representative or attorney. The regulation also states that records can only be viewed by individuals directly involved in the patient's treatment.

The Constitutional Court has also emphasized that whether a medical intervention has been performed in accordance with medical rules can largely be determined by examining the records from the diagnosis and treatment process; and that the recording and reasonable retention of diagnostic and treatment data is the responsibility of the healthcare institution. According to the Constitutional Court, if the responsibility of the healthcare institution cannot be assessed due to the failure to provide information or documents that should be in the patient's file, this should not be interpreted against the patient.

Therefore, cancer records should include not only the patient's discharge summary report but also all examination notes, laboratory results, radiology images, pathology reports, biopsy block/slide information, consultation records, tumor board decisions, chemotherapy protocols, radiotherapy plans, surgical notes, and follow-up records.

Late Diagnosis or Incorrect Treatment of Cancer in a Private Hospital

If cancer is diagnosed late or treated incorrectly in a private hospital, private clinic, private imaging center, private laboratory, or private oncology center, private legal liability arises. A private hospital may be held responsible not only for the individual error of the physician but also for matters such as communicating test results to the patient, following up on reports, organizing pathology and radiology procedures, laboratory safety, oncology planning, and patient record keeping.

Since private healthcare services can often be considered consumer transactions, consumer law provisions may also come into play. The Ministry of Trade's current legislation page includes Law No. 6502 on Consumer Protection and its secondary legislation; claims for defective services, breach of contract, and compensation in cases involving services received for a fee from a private healthcare institution can be evaluated together on a case-by-case basis.

The private hospital's defense that "the patient did not follow up on the results" is not sufficient in every case. If the report indicates a suspicion of cancer, it should be investigated whether the patient was informed, whether a follow-up appointment was scheduled, whether a warning was written in the patient's file, and whether the relevant physician saw the report.

Late Diagnosis or Incorrect Treatment of Cancer at State Hospitals

If cancer is diagnosed late or treated incorrectly in a state hospital, city hospital, training and research hospital, or public university hospital, the legal recourse often falls under administrative law. Healthcare services in state hospitals are public services. If this service is poorly provided, delayed, or not provided at all, the administration is considered to have committed a service defect.

According to Article 13 of the Administrative Procedure Law No. 2577, individuals whose rights have been violated by administrative actions must apply to the relevant administration for the fulfillment of their rights within one year from the date they learned of the action, and in any case within five years from the date of the action, before filing a lawsuit; if the request is rejected or no response is given within thirty days, a lawsuit may be filed.

Therefore, if there is an allegation of delayed cancer diagnosis in a public hospital, a detailed application should be made to the relevant administration before filing a lawsuit. The application should clearly state the chronology of the event, at what stage the delay occurred, the nature of the damage, the amount of material and moral compensation requested, and the records required.

What types of compensation can be claimed?

Patients who suffer harm due to late diagnosis or incorrect treatment of cancer may claim financial and non-financial compensation if the conditions are met.

Compensation claims may include medical expenses, surgery costs, chemotherapy/radiotherapy costs, medication costs, private hospital expenses, examination and imaging costs, intensive care costs, rehabilitation costs, travel and accommodation costs, caregiver costs, temporary disability, permanent disability, loss of earnings, and disruption of economic future.

If a patient has had to undergo more intensive treatment due to a late diagnosis of cancer, these additional treatment costs and the resulting decrease in quality of life should be taken into account in the compensation calculation. If the patient has suffered organ loss, permanent functional loss, or loss of working capacity, disability and incapacity calculations should be made.

Compensation for emotional distress is claimed due to the fear experienced by the patient, anxiety about death, the arduous treatment process, organ loss, decreased quality of life, impact on family life, psychological trauma, and reduced chances of treatment. If the patient has passed away, their relatives may claim compensation for loss of support, funeral expenses, and compensation for emotional distress.

How is a late diagnosis of cancer proven?

In cases of delayed cancer diagnosis, proof is often established through retrospective review of past records. When did the patient first present with what symptoms? What tests were performed? What were the findings? What reports were issued? Were the suspicious findings in the reports followed up? When was the biopsy performed? When was the definitive diagnosis made? When did treatment begin? These questions must be analyzed hour by hour, day by day, and month by month.

Evidence that can be used includes initial admission records, family physician records, emergency room records, outpatient examination notes, laboratory results, radiology images, radiology reports, pathology reports, biopsy records, surgical notes, chemotherapy protocols, radiotherapy plans, tumor board decisions, epicrises, prescriptions, referral documents, and patient correspondence.

Previous imaging records are particularly important. Even if the report is "normal," there may be visible signs of cancer in the image. Therefore, digital copies of MRI, CT scans, mammograms, ultrasounds, or X-rays should be made and submitted for expert review.

The Importance of Expert Reports

In cancer cases involving delayed diagnosis or incorrect treatment, expert reports determine the outcome of the case. The expert panel should include an oncologist, a specialist in the relevant surgical branch, a radiologist, a pathologist, and, depending on the nature of the case, specialists in radiation oncology, nuclear medicine, gastroenterology, pulmonary diseases, obstetrics and gynecology, dermatology, general surgery, or forensic medicine.

The expert witness must answer the following questions: Were there any findings suggesting cancer at the time of initial presentation? Which tests should the physician have ordered? Were there any errors in the imaging or pathology report? Was the biopsy or further tests delayed? Did the delay alter the stage of the disease? Would the treatment options have been different if the diagnosis had been made earlier? Was the treatment administered in accordance with current medical standards? Was there a causal link between the harm and the delayed/erroneous treatment?

Incomplete expert reports should be challenged. In particular, general statements such as "cancer may have had an aggressive course" or "the outcome might not have changed" are insufficient. The report needs to include concrete records, previous images, pathology material, the diagnosis-treatment timeline, and a detailed assessment of the impact of delay on the prognosis.

Can a criminal investigation be opened?

If cancer is diagnosed late or treated incorrectly, resulting in serious bodily harm or death, a criminal investigation may be initiated. Depending on the nature of the incident, the crimes of negligent injury or negligent homicide may be discussed. In investigations conducted due to medical procedures and practices of healthcare professionals, the Professional Responsibility Board process under Annex 18 of the Basic Law on Health Services No. 3359 may also be considered.

Criminal investigations and civil lawsuits serve different purposes. A criminal investigation examines the criminal liability of healthcare personnel. A civil lawsuit, on the other hand, aims to compensate the patient or their relatives for the material and moral damages they have suffered. However, forensic or expert reports in a criminal case can be important evidence in a civil lawsuit.

What should the patient or their relatives do?

If there is suspicion of delayed cancer diagnosis or incorrect treatment, the first thing to do is to gather all medical records. Not only the discharge summary, but also outpatient notes, test results, pathology reports, radiology images, biopsy material information, tumor board decisions, and treatment protocols should be requested in writing from the hospital.

The second step is to establish a chronology of events. When did the initial complaint begin? When was the first application made? Which tests were requested or not requested? When was the suspected case report issued? When was the patient called in for follow-up? When was the biopsy performed? When did treatment begin? This chronology forms the basis of the expert examination.

The third step is to correctly distinguish between private and public hospitals. In private hospitals, private law, consumer law, and malpractice liability come into play; in public hospitals, administrative appeals and full judicial proceedings become relevant.

The fourth step is to identify the damages. If the patient is alive, this includes medical expenses, disability, invalidity, care expenses, and emotional distress; if the patient has passed away, it includes loss of support, funeral expenses, and claims for moral damages by relatives.

Conclusion: Late diagnosis and incorrect treatment in cancer can lead to serious consequences

In cancer treatment, late diagnosis or incorrect treatment can directly affect a patient's lifespan, treatment options, organ function, working capacity, and quality of life. Not every late cancer diagnosis is a medical error; however, legal liability may arise if the patient's complaints and findings are ignored, necessary tests are not performed, there is a radiology or pathology error, a suspicious report is not followed up, a biopsy is delayed, or treatment is not started in a timely manner.

In such cases, success depends not only on the existence of a bad outcome, but also on demonstrating, with concrete evidence, at what stage the late diagnosis occurred, which medical standard was violated, how the harm was aggravated, and the causal link. Previous imaging records, pathology material, tumor board decisions, treatment protocols, and the timeline in the patient's file are of crucial importance.

A patient harmed by cancer can claim compensation for additional treatment costs, disability benefits, care expenses, loss of future economic prospects, and moral damages. If the patient has passed away, their relatives can claim compensation for loss of support and moral damages. Therefore, in cases where there is suspicion of delayed cancer diagnosis or erroneous treatment, medical records should be collected without delay, the case should be analyzed by specialist physicians and lawyers, and the appropriate legal course of action should be chosen, taking into account whether the treatment was provided in a private or public hospital.
