Do over one in five breast cancers detected by mammography alone really spontaneously regress?
It figures. Last Wednesday, right before the four-day Thanksgiving holiday weekend, as I was far more interested in preparing to have family over the next day than in what was going on in the medical news or the blogs, the results of a most fascinating study hit the news. In Medscape, the title of the news report was Mammography Study Suggests Some...
The (Not-So-)Beautiful (Un)Truth about the Gerson protocol and cancer quackery
Note added by editor: The complete movie is now available on YouTube: Although this blog is about medicine, specifically the scientific basis of medicine and threats to the scientific basis of medicine regardless of the source, several of us also have an interest in other forms of pseudoscience and threats to other branches of science. One branch of science that is, not...
High dose vitamin C and cancer: Has Linus Pauling been vindicated?
Treating cancer with high-doses of vitamin C is a zombie idea that began with Linus Pauling, and has failed to die ever since. But has new research vindicated this idea? No. No in any meaningful way. This work is the very definition of a long run for a short slide.
Early detection of cancer, part 2: Breast cancer and MRI
Note: If you haven’t already, you should read PART 1 of this two-part series. It defines several terms that I will be using in this post, and I don’t plan on explaining them again, given that they were explained in detail in Part 1. Of course, if you’re a medical professional and already know what lead time bias, length bias, and stage...
The early detection of cancer and improved survival: More complicated than most people think
“Early detection of cancer saves lives.” How many times have you heard this statement or something resembling it? It’s a common assumption (indeed, a seemingly common sense assumption) that detecting cancer early is always a good thing. Why wouldn’t it always be a good thing, after all? For many cancers, such as breast cancer and colon cancer, there’s little doubt tha early...
Ultrasound Screening: Misleading the Public
There is a new industry offering preventive health screening services direct to the public. A few years ago it was common to see ads for whole body CT scan screening at free-standing CT centers. That fad sort of faded away after numerous organizations pointed out that there was considerable radiation involved and the dangers outweighed any potential benefits. Now what I most commonly...
Oprah’s buddy Dr. Christiane Northrup and breast thermography: The opportunistic promotion of quackery
Dr. Christiane Northrup came to fame as Oprah Winfrey's resident women's health expert. Unfortunately, she's using that fame to promote the unproven breast cancer screening modality thermography during Breast Cancer Awareness Month.
False balance in an NBC news story on whole body MRI scans
Over the weekend, NBC News aired a story on whole body MRI scans. Although it did include the usual cautions about false positives and the harm they cause, the caution was diluted by the story's focus a rare case of a woman who had a brain tumor detected. Overall, it was false balance that reminded me of vaccine/autism stories 20 years ago.
Health misinformation now has powerful allies
Misinformation and conspiracy theories about health had long been a growing problem before the pandemic, but it took COVID-19 to get the government and researchers to take it seriously. Now, a new report in The Washington Post adds to previous reporting from multiple sources describing how allies of misinformation—and not just health misinformation—are striking back under the guise of defending "free speech."
Quoth quacks, “The medical consensus has changed before, making my quackery science!”
Brave maverick doctors (i.e., quacks) have long tried to portray themselves as "innovators" challenging an ossified medical consensus for the good of patients. This tradition continues among COVID-19 quacks, in particular the Frontline COVID-19 Critical Care Alliance and its founders.
