Cancer is a broad term for a variety of diseases which can affect nearly every part of the body. It obvious to say early detection is crucial for improving survival rates and quality of life. However, some cancers remain difficult to diagnose, either because of their subtle symptoms, the lack of effective screening tools, or how they mimic other less serious conditions.
I was considering this because of this article on the BBC about cancer of the bile duct as I had a very similar case to investigate in which my client had suffered symptoms but was not diagnosed early enough to have lifesaving treatment. This type of cancer is rare but listed below are the more common cancers which can be difficult to detect in their early stages due to how they develop, their location or their non-specific symptoms
These cancers often don’t present with obvious signs until they are in advanced stages.
Pancreatic Cancer
One of the most notoriously hard cancers to diagnose, pancreatic cancer often does not cause symptoms until it has already spread. The pancreas is located deep within the abdomen, and its tumours may not show up on physical exams or be detected by standard imaging tests in the early stages. Symptoms like abdominal pain, jaundice, and weight loss may appear late in the disease progression and can be easily attributed to other, less serious conditions.
Ovarian Cancer
Ovarian cancer is often called the "silent killer" because its early symptoms are vague and often resemble those of common gastrointestinal issues, such as bloating, indigestion, and abdominal discomfort. These symptoms are frequently overlooked or misdiagnosed, leading to delays in detection. By the time ovarian cancer is diagnosed, it is often in an advanced stage, making treatment more difficult and less effective.
Lung Cancer
Despite smoking being a major risk factor, lung cancer can also occur in non-smokers, and its symptoms—persistent cough, chest pain, and shortness of breath—are common to several other respiratory conditions. Because of this overlap, lung cancer is often not suspected or diagnosed early. Additionally, the absence of an effective screening method for people who don’t have clear risk factors can delay diagnosis.
Colorectal Cancer
This can be difficult to diagnose, especially in younger patients or those without a family history of the disease. Symptoms like changes in bowel habits, blood in the stool, or abdominal pain can be attributed to benign conditions like haemorrhoids or irritable bowel syndrome. As a result, these symptoms may be ignored or misdiagnosed, delaying crucial treatment.
These cancers are difficult to diagnose for several reasons
- Nonspecific Symptoms: Many cancers present with symptoms that are vague or similar to those of other, less serious diseases. For example, fatigue, weight loss, and digestive issues could indicate a range of conditions, not just cancer.
- Lack of Screening Tests: While there are well-established screening methods for cancers like breast (mammography) and cervical (Pap smears) cancer, other cancers do not have such routine screening options. However, there is no standard screening for pancreatic or ovarian cancer, meaning these cancers are often detected only after symptoms have already appeared.
- Asymptomatic Early Stages: Many cancers grow slowly or don’t cause noticeable symptoms in their early stages. This lack of early signs can lead to missed opportunities for early diagnosis when treatment might be more effective.
- Imaging Limitations: Some cancers, such as pancreatic cancer, can be difficult to detect on imaging tests. The lack of specific or highly sensitive diagnostic tools means that cancers may not be visible in routine scans until they are more advanced.
Clinical negligence claims arise when a healthcare provider’s failure to diagnose cancer in a timely manner leads to harm or worsened outcomes for the patient. When doctors overlook critical symptoms, fail to order appropriate tests, or misinterpret test results, it can result in delayed diagnoses. The following scenarios may lead to clinical negligence claims:
- Failure to Investigate Symptoms Thoroughly: If a patient presents with persistent or unusual symptoms that suggest cancer, but the healthcare provider fails to conduct the necessary tests or referrals, this may constitute negligence. For example, if a patient with unexplained weight loss and abdominal pain is not referred for imaging or a biopsy, and a cancer is missed, it may be grounds for a claim.
- Misinterpretation of Test Results: Errors in reading diagnostic tests—such as blood tests, CT scans, or MRIs—can delay diagnosis and result in the cancer progressing to an advanced stage. If these misinterpretations cause harm, patients may have grounds for a negligence claim.
- Failure to Follow Up on Abnormal Results: When a test reveals abnormal results but the healthcare provider does not take the next steps to confirm the diagnosis, the cancer can go undiagnosed for months or even years. This failure to follow up can lead to worsened health outcomes, giving rise to a potential negligence claim.
- Delayed Referrals to Specialists: If a general practitioner or primary care doctor fails to refer a patient to a specialist—such as an oncologist—when appropriate symptoms are present, it can lead to delays in diagnosis and treatment. A failure to refer to specialists could be considered a breach of duty if it causes harm to the patient.
Diagnosing cancer early is crucial to improving patient outcomes, but some cancers remain difficult to detect. When these cancers are not diagnosed in time due to negligence, patients may suffer worse prognoses and reduced treatment options. In such cases, a clinical negligence claim may arise if it can be shown that the healthcare provider’s actions, or lack thereof, caused significant harm to the patient. It is essential for both patients and healthcare providers to be vigilant and proactive in recognizing symptoms and ensuring timely diagnoses, particularly for hard-to-diagnose cancers.
