Reader Rick Zhang used the website’s “Contact Me” on September 25, 2023 to inquire:
"Hello Professor Lin: I saw 2023.09.23 on [Health 2.0] Posted article [Vikin C and E accelerate tumor growth and transfer? Latest research reveals: May malignant lung cancer]. I only found in your website that vitamin C does not seem to have any effect on tumor treatment, and the US FDA has not approved this method at all. However, there is still a speech on the Internet for treating cancer with high-unit vitamin C. If it is just not done It's okay to use it, but if it accelerates the growth and transfer of tumors, isn't this harmful? Can you please be suspicious? Thank you! "The news about "vitamin C and E accelerates the growth and transfer of tumors" has been reported by mainstream media in the United States and Taiwan, and the reason is a research paper published on August 31, 2023. stimulate BACH1-dependent tumor angiogenesis. (Antioxidants stimulate BACH1-dependent tumor angiogenesis). There are 20 authors in this paper, and the communication author (that is, the leader of the research team) is Dr. Martin Bergo, the current vice president of the Karolinska Medical College in Sweden. When he was doing postdoctoral research at the University of California, San Francisco (UCSF) more than 20 years ago, I was an associate professor at UCSF.
As early as 2014, a six-person team led by him had already published Antioxidants accelerate lung cancer progression in mice. The article begins with the saying: "The concept of antioxidants that help fight cancer has become deeply rooted in the general population with the promotion of food supplements."
It is worth noting that this article has a accompanying comment, and the title is The Dark Side of Antioxidants. Its first paragraph is: "Antioxidants or compounds that prevent other molecules from oxidizing are widely sold as dietary supplements with various health claims. This is usually due to a characteristic of antioxidants, which is to reduce the risk of cancer. However, in recent years, many studies have mentioned this statement There is doubt because new evidence suggests that antioxidants may actually increase the risk of certain cancers. ”
In fact, I published two articles on the "Dark Side of Antioxidants" (also called "Antioxidant Paradox") shortly after I founded the website in 2016. Please see:
antioxidants cannot be taken in large quantities. Can anti-aging and disease-resistant?
However, there is no way to do it, and to this day, "antioxidants" are still "a widespread dietary supplement with various health claims."
No matter what, the "antioxidants" mentioned by Dr. Martin Bergo this article this year are not just vitamin C and E, but also N-acetylcysteine (simple NAC, Chinese N-acetylcysteine). However, the media has not reported that NAC may also accelerate tumor growth and transfer, which is clearly because it is not as famous as Vitamin C and E. What’s even more funny is that the media has reported that NAC can cure cancer. For example, the pancreatic cancer transferred to the peritoneum published by Yuanqi.com on 2018-1-26, and the cold medicine saved his life. (For more information, please see my posting of phlegm-relieving medicine for cancer treatment: Average?)
As for what reader Rick asked, "the theory of treating cancer with high-unit vitamin C is still circulating on the Internet", it is indeed a matter. There are several "famous doctors" in Taiwan that open advertising to recruit businesses, and I have also published articles to blame, such as:
2019: Vitamin C fights cancer? : In short, "cell molecular pharmacology" is just a bluffing name, and the alternative methods it advocates, including static injection of large doses of vitamin C, not only does not have any effect, but may have counterproductive effects.
2020: Can vitamin C fight Wuhan pneumonia/influenza and treat cancer? : There is not enough data to indicate the correlation between vitamin C status and the risk of suffering from a specific type of cancer. Currently, evidence on the treatment of cancer with static injection of vitamin C is limited to observational studies.
2021: Vitamin C treats cancer? Lipid quality? High dose static injection? : The Cancer Institute in the UK even said: "Some studies even believe that Vitamin C interferes with some anti-cancer drugs, and one study shows that it can even protect breast cancer cells from the drug tamoxifen."
2023: Vitamin's theory and nonsense: Although Vitamin D is a red chicken, Vitamin C has been in danger for nearly 40 years, and why is it still the number one in all water-soluble vitamin supplements. Especially in alternative cancer treatments, Vitamin C injection is really a money-loss tree for the black-hearted doctor.
Please note that Dr. Martin Bergo's two papers were studied using mouse and cell models, so the results cannot be directly applied to human cancer. More importantly, the antioxidants (including vitamin C and E) mentioned in the paper refer to large doses (from supplements) rather than micro doses (from food).
I published Vitamin: Definition in 2019. I found that there are categories that say the definition of vitamin is "the trace nutrients from food", but unfortunately, the vitamins sold on the market have turned against this definition.
