Ivermectin repurposing

COVID-19 antivax quacks are now “repurposing” ivermectin for cancer

A year ago, I noticed that COVID-19 quacks were touting the "repurposing" of ivermectin to treat cancer. Now, familiar COVID-19 antivaxxers—cough, cough, FLCCC—have turbocharged this quackery.

Last week, I discussed Dr. William Makis' false claims of "turbo cancers" due to COVID-19 vaccines. Now it's hydroxychloroquine-promoting epidemiologist Harvey Risch's turn.

Colonoscopy: More Misinformation from Mercola

Joseph Mercola, D.O., runs the website mercola.com which is full of misinformation, advocates all kinds of questionable alternative treatments including homeopathy, and discourages vaccination and other aspects of conventional medicine. Like Dr. Oz and Andrew Weil, he is more dangerous than easily recognizable quacks in that he combines some good medical information with egregious misinformation, and readers who know he is right...

Recent Developments and Recurring Dilemmas in Cancer Screening: Colon, Lung, Thyroid

A new stool DNA test was recently approved by the FDA for colon cancer screening. My first reaction was “Yay! I hope it’s good enough to replace all those unpleasant, expensive screening colonoscopies.” But of course, things are never that simple. I wanted to explain the new test for our readers; but before I could start writing, some other issues in cancer...

Colonoscopy and Other Colorectal Cancer Screening Options: An Update

When I wrote about colonoscopy in 2010, colonoscopy was thought to be the best screening test for colorectal cancer because it could visualize the entire colon and could remove adenomas that were precursors of cancer. But only fecal occult blood testing (FOBT) and sigmoidoscopy had been proven to decrease colorectal cancer incidence and mortality (by 16% and 28%, respectively). Observational evidence suggested...

Chris Wark didn't beat cancer

Yes, Chris beat cancer, but it wasn’t quackery that cured him

Chris Wark is a young man who was diagnosed with stage 3 colon cancer in 2003 at age 26. He underwent appropriate surgery for his cancer but declined adjuvant chemotherapy in favor of quackery. Now promotes his testimonial, in which he tries to convince people that it was the quackery, rather than the surgery, that cured him. He even claims that surgery...

Virtual Colonoscopy Can Be Hazardous to Your Health

The US Preventive Services Task Force (USPSTF) recommends that everyone aged 50-75 be screened for colon cancer with any one of three options: colonoscopy every 10 years, flexible sigmoidoscopy every 5 years, or fecal occult blood testing (FOBT) every year. Conventional colonoscopy is considered the “gold standard” since it allows for direct detection and biopsy of early cancers and removal of precancerous...

Mike Adams on Dr. Mehmet Oz’s colon polyps: “Spontaneous” disease?

Given that it’s a holiday and I debated whether or not I even wanted to post anything today, I think I’ll keep things light and uncharacteristically brief today. After all, not every post can be like last week’s epic on Avastin or the week before’s epic on peer review. That’s a lot of work, and it is a holiday, after all. Besides,...

Questioning Colonoscopy

Everybody knows that colonoscopy is the best test to screen for colorectal cancer and that colonoscopies save lives. Everybody may be wrong. Colonoscopy is increasingly viewed as the gold standard for colorectal cancer screening, but its reputation is not based on solid evidence. In reality,  it is not yet known for certain whether colonoscopy can help reduce the number of deaths from...
