The most misdiagnosed cancers in America are also some of the most deadly when detected late.
When it comes to treating almost any kind of cancer, early detection is crucial. The sooner you start getting treatment, the better your prognosis will be. Yet doctors frequently miss or misdiagnose certain kinds of cancer. Unfortunately, these are precisely the cancers in which a delay in treatment is often deadly.
These five cancers are among the most commonly misdiagnosed cancers in the U.S.
According to research conducted by the National Coalition on Health Care and Best Doctors, physicians in the U.S. believe that lymphoma is “the most misdiagnosed cancer,” Boston Magazine reported.
Lymphoma is cancer of the cells that make up the body’s immune system. Both Hodgkin lymphoma and non-Hodgkin lymphoma begin in the white blood cells known as lymphocytes. It’s also possible to develop lymphoma of the skin.
Even the enlarged lymph nodes that characterize lymphoma are a nonspecific symptom. Doctors often attribute these signs to the common cold or an infection.
2. Breast Cancer
Breast cancer is so commonly misdiagnosed that the delayed detection of breast cancer is “the most frequent reason for lawsuits against doctors,” the National Association of Science Writers reported.
As many as 31 percent of breast cancers are overdiagnosed, according to the New England Journal of Medicine. This means that doctors misdiagnose precancerous cells that won’t cause clinical problems or endanger the patient’s life as full-fledged cancer. Overdiagnosis causes healthy patients to undergo drastic cancer treatments for no reason.
On the other hand, mammograms miss about 16 percent of breast cancer cases, the Susan G. Komen organization reported. For these patients, the delay in detecting and treating breast cancer could be deadly.
Early stage breast cancer has a survival rate of nearly 100 percent. However, when breast cancer progresses to stage IV, just 22 percent of patients survive for five years or longer.
3. Colon Cancer
Another of the cancers doctors most commonly miss is colorectal cancer.
Doctors usually detect cancer of the colon, rectum, or bowel by performing a colonoscopy. This procedure, recommended for both men and women ages 50 and older, uses tubes and cameras to allow doctors to view the inside of the colon while the patient is sedated.
A colonoscopy is one screening test that doesn’t just identify cancer, but can actually prevent it. Most colon cancers begin as noncancerous tumors called polyps. During a colonoscopy, doctors can biopsy or even remove polyps, so they never get the chance to develop into cancer.
Any delay in diagnosing colon cancer is a serious situation. Survival rate drops from 92 percent at stage I to just 11 percent at stage IV.
4. Lung Cancer
Another type of cancer that is devastating when misdiagnosed is lung cancer. Among both men and women, lung cancer is the second most common cancer in America. Unfortunately, many patients don’t learn they have lung cancer until it’s too late.
Why not? For one thing, lung cancer often grows slowly. While that’s good in the sense that you can treat the cancer if caught early, it also makes the condition difficult to detect. Lung cancer presents few symptoms in the early stages.
Even the symptoms that patients do experience often get misdiagnosed as something else. Doctors may mistake shortness of breath for asthma or COPD. They confuse the chronic cough that lung cancer causes with pneumonia or bronchitis. If you’re coughing up blood, doctors might assume you have tuberculosis when you really have lung cancer.
The longer lung cancer goes undiagnosed, the worse the patient’s prognosis becomes. At stage 0, your survival rate is 60 to 80 percent, but that rate drops to only one percent when the cancer advances to stage IV.
5. Skin Cancers
Research has shown that melanoma – a rare but deadly form of skin cancer – is also among the most commonly misdiagnosed cancers in the U.S. At early stages, skin cancer may mimic a non-cancerous condition, like eczema. Doctors who dismiss suspicious skin marks and growths without further testing could allow cancer to progress to life-threatening stages.
Besides attributing cancer symptoms to benign causes, one of the biggest – and most surprising – reasons for cancer misdiagnosis is an error in the lab. Biopsies, the collection of body tissue samples for testing and analysis, are widely used in cancer detection. They’re also a lot more fallible than most people realize, especially when it comes to diagnosing skin cancers.
The people who work in laboratories analyzing these samples are called pathologists. While pathologists can specialize in interpreting a certain kind of cancer, many don’t. Those who do specialize in one kind of cancer may sometimes have to weigh in on samples that they’re not experts in.
When pathologists try to look for a kind of cancer they haven’t specialized in, “many mistakes” occur, ABC News reported. Skin cancer is among the types of cancer most prone to pathologist errors.
Dealing With a Delayed Cancer Diagnosis
When doctors misdiagnose cancer, they prevent patients from getting the treatment they need when they need it. This mistake allows treatable early-stage cancer to advance to late-stage or even terminal cancer.
As soon as you find out that you have cancer – no matter what stage it is – you should speak with a doctor you trust about your options. It’s often a good idea to seek a second opinion, even if you think your doctor is competent, because diagnostic errors are far too common.
Remember that any further delay could make your bad prognosis even worse. It’s important that you’re getting the care you need right now.
However, no matter how quickly you act, it doesn’t change the delay in getting your treatment in the first place or how much your condition has worsened as a result of that delay. If you believe that your doctor should have diagnosed your cancer earlier, then you should look into a missed cancer diagnosis lawsuit. A misdiagnosis attorney can help you find out what your doctor did wrong and make sure you get the compensation you need to afford the very best late-stage cancer care.
