A patient is Australia has reportedly been administered chemotherapy for six months — before the doctors found out she did not have cancer, believe it or not. What sounds like a patient’s worst nightmare happens more often than the medical system is willing to admit.
In the case of the woman in Australia, she previously had a tumor removed three years prior. When she came back for a review, her surgeon did a CT scan and diagnosed her with stage 4 liver cancer. The problem? Her oncologist never did any tests to confirm this diagnosis and went ahead with chemotherapy, reported ABC News Australia.
When the “cancer” did not react to chemotherapy, the doctors finally performed the needed tests only to find out that the tumors were benign, and the woman did not have cancer after all. Perhaps they had feared that the cancer would return; at any rate, a woman was given one of the most dangerous and side effect-ridden treatments the medical industry can muster without just cause.
And as fate would have it, it’s not only the returning cancers that get misdiagnosed. Recent reviews have shown that a large percentage of all cancers are misdiagnosed completely, largely due to tests that cause overdiagnosis.

1.3 Million Women Were Overdiagnosed with Breast Cancer
Screening mammography is arguably the tool responsible for the largest number of overdiagnosis of cancer. A data review study from The New England Journal of Medicine estimated that 1.3 million women in the U.S., over the age of 40, were overdiagnosed with breast cancer in the last 30 years. In 2008, 70,000 women were overdiagnosed, meaning the tumors that were detected would never lead to clinical symptoms and were likely to be harmless. A total of 31% of all breast cancer diagnoses that year were due to overdiagnosis.
50-90% of Thyroid Cancers are Overdiagnosed
The World Health Organization (WHO) recently reported that International Agency for Research on Cancer (IARC) found out the growing thyroid cancer epidemic is due to overdiagnosis of the disease. The thyroid tumors discovered in as many as 90% of all patients in high-income countries are likely to never lead to any symptoms during their lifetime.
“The majority of the overdiagnosed thyroid cancer cases undergo total thyroidectomy and frequently other harmful treatments, like neck lymph node dissection and radiotherapy, without proven benefits in terms of improved survival,” said Dr. Silvia Franceschi, one of the authors of the article “Cancer Incidence in Five Continents.”

The majority of the overdiagnoses happen in the Republic of Korea, up to 90%. In the U.S. the estimated number of overdiagnoses is between 70-80%. Similar numbers were observed in Australia, France, and Italy. In the Nordic countries, and England and Scotland, about 50% are overdiagnosed.
“Countries such as the USA, Italy, and France have been most severely affected by overdiagnosis of thyroid cancer since the 1980s, after the introduction of ultrasonography,” said Dr. Salvatore Vaccarella, the IARC staff scientist.
Overdiagnosis in Other Cancers
The List of Patients Who Fell Victim to Misdiagnosis and Overdiagnosis Grows Each Year
Misdiagnosis is when a pathologist finds benign cells but classifies them as cancerous. An overdiagnosis is when a screening finds a tumor that would not be found by other tests, is likely to not have caused any symptoms, or be harmful during the person’s lifetime.
Both hurt the patient because they have to go through unnecessary toxic treatments and surgeries they never needed.
“If someone makes a mistake we don’t always fire them. If we did that we wouldn’t have any staff,” said Dr. Charles Pain, executive director of medical services at Top End Health Service (TEHS), which oversees the hospitals the women were treated at.
