Misleading cancer books abound on Amazon

Researchers from the London School of Hygiene & Tropical Medicine, the University of Alberta’s Health Law Institute, and the University of Edinburgh’s Global Health Policy Unit searched for “cancer cure” on Amazon.com and reviewed the titles and descriptions of the top 1,000 English-language books from search results to determine whether the books provided cancer misinformation. Nearly half—494 books—were found to contain misleading cancer treatment or cure information. Of those:

• 97.3% of the misleading books were found to promote a treatment it claims can or has cured cancer
• 39.3% oversimplify cancer and cancer treatment
• 38.33% falsely justify ineffective treatments as science-based
• 34.2% attempt to discredit conventional cancer treatments
• 26.9% promote one treatment as curing all types of cancer and/or other diseases
• 26.7% present one treatment to cure all types of cancer
• 24.1% feature people with cancer, their families, or health practitioners finding new cancer cures and treatment options
• 16.6% claim cancer cures already exist but are hidden or banned because of financial interests from the pharmaceutical industry, legal battles with regulators or medical associations, and conspiracies to ruin reputations

The researchers concluded:

These results demonstrate that misleading cancer cure and treatment books are for sale, visible, and seemingly prevalent on Amazon.com. Nearly half of the “cancer cure” books for sale offered misleading and potentially harmful cancer treatment misinformation. Misleading books directly claimed to have efficacious cures for cancer, undermined scientifically supported treatments, misapplied scientific reasoning, oversimplified cancer and cancer treatments, and promoted conspiracy theories. Books offered information that may delay or encourage patients to opt out of best-standard treatments and create false hope.

Our study contributes to the increasing research documenting the presence, spread, and mechanisms of medical misinformation on Amazon. Notably, Amazon’s algorithm has been reported to amplify books with vaccine misinformation. In other cases, Amazon has been found to host products selling fake autism cures and promote COVID-19 misinformation. Amazon’s search results have been found to rank products with misinformation higher than sources debunking misinformation. Concerningly, misinformation in Amazon-hosted products may be amplified by fake product reviews, which are associated with a causal increase in product sales.

FDA warns consumers not to use potentially contaminated homeopathic nasal spray

 The U.S. Food and Drug Administration (FDA) is warning consumers and health care professionals not to use SnoreStop Nasal Spray, distributed by Green Pharmaceuticals Inc. of Camarillo, California. The product may have microbial contamination that can potentially lead to infection, which can be life-threatening in certain patient populations such as immune-compromised individuals. SnoreStop Nasal Spray, an unapproved product, was previously sold on the company’s website and other sites and marketed for children beginning at age 5 and adults with unproven claims it opens air passages and relieves congestion.

FDA inspected the Green Pharmaceuticals facility in April 2024 and uncovered laboratory test results that reported significant microbial contamination in SnoreStop Nasal Spray lot number 2460. FDA investigators found evidence some products in this lot had been repackaged and distributed to customers for use as single units and in kits. On August 8, 2024, Green Pharmaceutical destroyed the remaining SnoreStop Nasal Spray from lot 2460 and other products the company had on-hand. FDA recommended Green Pharmaceuticals recall their SnoreStop Nasal Spray product on Aug. 13 and Sept. 12, 2024. The agency repeated its recall recommendation multiple times during this time, but as of September 18, the company did not recall the product from the market.

FDA issued a warning letter to Green Pharmaceuticals on December16, 2022, for distributing unapproved drugs and lacking quality controls over the products they sell. Additionally, the company voluntarily recalled one lot of SnoreStop NasoSpray on June 9, 2022, after FDA testing found the product contained microbial contamination identified as Providencia rettgeri. SnoreStop NasoSpray was renamed SnoreStop Nasal Spray following this recall. [FDA warns consumers not to use SnoreStop Nasal Spray by Green Pharmaceuticals due to potential contamination. FDA Drug Safety Communication, Sept 18, 2024]

According to the FDA’s announcement, the company subsequently stopped selling nasal spray products on its website. When the webpage to order the product was active, it indicated it was a homeopathic preparation with seven ingredients, five of which were diluted 6X or one part per million, one diluted 4X, and one diluted 12X. A blog post that remains on the SnoreStop website describes the nasal spray as “the best quality natural nasal spray to reduce snoring.” The website still has a page for ordering SnoreStop for Pets, described as a “homeopathic anti-snoring oral spray” and “the only natural anti-snoring solution for your pet’s snoring.” The FDA’s announcement said nothing about SnoreStop for Pets even though it has the same ingredient list as the potentially contaminated nasal spray.

Acupuncture paper in JAMA Internal Medicine denounced

 Steven Novella, M.D., an associate professor of neurology at Yale School of Medicine, has described the paper “Acupuncture vs, Sham Acupuncture for Chronic Sciatica from Herniated Disk: A Randomized Clinical Trial,” as “scientifically worthless.” The paper was published October 14, 2024, in JAMA Internal Medicine. He noted:

. . .the study was not double-blinded, the sham treatment used was inappropriate, the measured outcome was subjective, acupuncture is of implausible value, and the study came out of China where such studies have a near 100% bias toward positive results.

An Editor’s Note in JAMA Internal Medicine asserted the acupuncture study was “methodologically rigorous” and acupuncture is “an effective, evidence-based, non-pharmacological treatment” for chronic sciatica. In contrast, Dr. Novella concluded: “Doctors, other clinical professionals, and medical scientists need to maintain the highest levels of skepticism toward any claims or treatments in medicine. Otherwise, we will slide into pseudoscience. History is very clear on this fact.”

Circuit court backs FDA’s authority to regulate adipose cell therapy as a drug

The 9th Circuit Court of Appeals has ruled that stromal vascular fraction (SVF)—a mixture of stem cells, other cells, and cell debris spun down from patients’ own fat cells—is a drug that can be regulated by the U.S. Food and Drug Administration (FDA), and is not exempt under the FDA’s “same surgical procedure” exception. In 2018, FDA sued the California Stem Cell Treatment Center and the related Cell Surgical Network over its SVF treatments. In 2022, a federal judge in California sided with the center, ruling that those treatments weren’t subject to regulation. But the FDA appealed and won. In a similar lawsuit brought by the FDA against Florida-based U.S. Stem Cell Clinic over its SVF treatments, the clinic lost its case in 2019 and its appeal was subsequently denied.
