The United States Food and Drug Administration () sent warning letters to 14 fraudulent cancer cure companies. Apricot kernels, herbs and other ingredients are the focus of Maggie Fox’s NBC News coverage of the actions.  

A cancer diagnosis of an individual, family member or friend is challenging and can cause extreme distress; people diagnosed with cancer may be desperate to try anything and vulnerable to these companies’ claims to “cure” or “treat” cancer. The companies making these inaccurate are a danger and represent an injustice to the people they claim to help.  

FALSE CLAIM:  “If a person eats 6-12 apricot kernels per day, they will never have to worry about cancer.”

This false claim is advertised on one of the companies’ websites. Cancer patients and their families may be vulnerable and more willing to put skepticism aside if they hear or read that something can cure cancer. But these companies go further than that. According to a blog post written by the ’s Donald Ashley, JD and Douglas Stearn, JD, “These companies use slick ads, videos, and other sophisticated marketing techniques, including testimonials about miraculous outcomes. Often a single product was promoted as a treatment or cure for multiple diseases in humans and animals (2).”

However, these products have not been tested. Claims that they cure or treat cancer are fake, and they are potentially dangerous. As Maggie Fox writes, “…’Everything Herbs’ was advertising apricot kernels, which contain deadly cyanide. Apricot seeds were the basis for amygdalin (laetrile), an unproven but popular “alternative” cancer therapy sold online and in overseas clinics since the 1970s, despite much evidence it is worthless.”

The issued warning letters to 14 companies regarding their fraudulent claims about their products: AIE Pharmaceuticals, Inc.; Amazing Sour Sop, Inc.; BioStar Technology International, LLC; Caudill Seed & Warehouse Inc.;; Everything Herbs; Hawk Dok Natural Salve, LLC; Healing Within Products & Services, Inc.; LifeVantage Corporation; Nature’s Treasure, Inc.; Oxygen Health Systems, LLC; Sunstone, Inc.; The Vibrant Health Store, LLC (dba Dr. Christopher’s Herbs); and The Vitamin C Foundation (3).

What does this mean for me?

The is responsible for “Protecting the public health by assuring the safety, effectiveness, quality, and security of human and veterinary drugs, vaccines and other biological products, and medical devices.” Drug companies seeking approval to sell a new drug are required to test it in many ways, from early experiments done a laboratory to seeing if the drug is safe and effective for use in humans.

Additionally, clinical guidelines have not been written for any of these products. As defined by the Institute of Medicine, clinical guidelines are “…systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances (4).” These guidelines are made after enough high-quality research studies are completed that support the use of the products in question. For example, many researchers and physicians from different academic institutions would have agree that eating 6-12 apricot kernels a day would prevent cancer for the guidelines to incorporate this practice.

Being diagnosed with cancer or experiencing a loved one going through cancer is difficult, and it is inappropriate, illegal and unethical for companies to promote products that have not been proven to be safe or effective. But because companies like these exist, cancer patients and their loved ones should be sure to confirm that the products or treatments they hear and read about are critically examined by trusted resources, such as the and a person’s own health care providers.

Dietary Supplements

National Comprehensive Cancer Network (NCCN) guidelines on survivorship include the following recommendations on dietary supplement use:

  • Taking dietary supplements is not recommended for most cancer survivors unless a patient has a known nutritional deficit, an inadequate diet or other indication (for example, ).
  • Little data exist to support the use of vitamins or other dietary supplements for cancer prevention, control or recurrence.
  • Taking vitamin supplements does not replace the need for a healthy diet. Patients should try to get nutrients from the foods they eat and the beverages they drink.
  • Providers should ask about supplement use at regular intervals, about a patient’s reasons for using supplements and the ingredients in those supplements.
  • Survivors of certain cancers are at risk of vitamin deficiencies based on cancer treatment (e.g., gastric cancer patients who have had a gastrectomy may be at risk of vitamin B12 and iron deficiencies).
  • NCCN recommends calcium and vitamin D supplements for people who have been prescribed denosumab or a bisphosphonate to treat bone or .
  • Patients taking multiple supplements and those in need of nutritional support should be referred to a registered dietitian or nutritionist, preferably one who is trained in supporting oncology patients.
