Recently, the entire MAHA movement was rightfully up-in-arms when Oracle's Executive Chairman and Chief Technology Officer, Larry Ellison, pushed AI-generated cancer mRNA injections developed in 48 hours. The health freedom movement has grown tired of experimental gene therapies and seek safer, more natural approaches to cancer prevention and treatment. Dr. John Catanzaro, founder of Neo7Bioscience, has demonstrated the potential of precision-engineered peptides and small molecules for personalized cancer care. Dr. William Makis and many others advocate for the use of Ivermectin and Fenbendazole in cancer treatment, which has shown extreme promise. Another promising but often overlooked approach in Western Medicine is the use of mushrooms for cancer. In this article, I will summarize the biological mechanisms, epidemiological evidence, and clinical data supporting the use of mushrooms in cancer prevention and treatment.
Biological Mechanisms
Pathak et al reviewed the immunomodulatory effect of mushrooms and their bioactive compounds in cancer:
Immunomodulation: Mushroom bioactive compounds, such as lentinan, schizophyllan, and maitake-D fraction, stimulate the immune system by activating macrophages, dendritic cells, and natural killer (NK) cells, enhancing cytokine production (e.g., IL-2, IL-6, TNF-α) and increasing anti-tumor immune responses.
Cell Cycle Arrest: Polysaccharides and other phytochemicals in mushrooms can halt cancer cell division at key regulatory checkpoints, particularly the G0/G1 and G2/M phases, thereby preventing tumor proliferation.
Apoptosis Induction: Mushrooms trigger programmed cell death (apoptosis) in cancer cells via both the intrinsic (mitochondrial) and extrinsic (death receptor) pathways, leading to DNA fragmentation and caspase activation, effectively eliminating malignant cells.
Angiogenesis Inhibition: Certain mushrooms, such as Ganoderma lucidum and Phellinus linteus, block the formation of new blood vessels (angiogenesis) that tumors need for growth by downregulating VEGF (vascular endothelial growth factor) and inhibiting endothelial cell proliferation.
Oxidative Stress Regulation: Mushroom compounds like ergothioneine, glutathione, and polyphenols neutralize reactive oxygen species (ROS), reducing oxidative DNA damage that contributes to carcinogenesis.
Epidemiological Evidence
Ba et al conducted a systematic review and meta-analysis of observational studies examining the association between mushroom consumption and cancer risk, finding a significant inverse relationship:
Overall Cancer Risk Reduction: Higher mushroom consumption was associated with a 34% lower risk of total cancer (Pooled RR: 0.66; 95% CI: 0.55–0.78; n = 17 studies).
Breast Cancer Risk Reduction: The strongest association was found for breast cancer, with a 35% lower risk in the highest mushroom consumption group (Pooled RR: 0.65; 95% CI: 0.52–0.81; n = 10 studies).
Non-Breast Cancer Risk Reduction: A more modest reduction in other types of cancer was observed (Pooled RR: 0.80; 95% CI: 0.66–0.97; n = 13 studies).
Dose-Response Relationship: A nonlinear dose-response was detected (P = 0.001), showing a 45% lower risk at 18g/day mushroom intake compared to 0g/day.
Clinical Data
Narayanan et al conducted a systematic review of clinical studies examining the use of medicinal mushrooms in cancer treatment, finding evidence of potential benefits in survival, immune response, and quality of life:
Study Scope:
Reviewed 39 clinical studies conducted between 2010 and 2020.
Examined 12 different medicinal mushroom preparations across various cancer types.
Most frequently studied mushrooms: PSK (Polysaccharide-K) from Turkey Tail (Trametes versicolor) (10 studies), Shiitake mycelia extract (Lentinula edodes) (8 studies), Huaier granules (Trametes robiniophila Murr.) (5 studies), and AHCC (active hexose correlated compound, a proprietary Shiitake extract) (5 studies).
Other mushrooms examined: Reishi (Ganoderma lucidum), Maitake (Grifola frondosa), Phellinus linteus, Agaricus blazei, and Chaga (Inonotus obliquus).
Most studied cancer types: gastric cancer (11 studies), breast cancer (8 studies), and prostate cancer (5 studies), with additional studies on colorectal, pancreatic, and esophageal cancers.
Survival Benefits:
Huaier granules improved overall survival (OS) and disease-free survival (DFS) in 2 studies on hepatocellular carcinoma (HCC) and 1 study on breast cancer.
PSK, a beta-glucan from Turkey Tail, improved survival outcomes in 4 gastric cancer studies when used as an adjuvant therapy.
Immune System Modulation:
11 studies reported positive immune responses, including increased natural killer (NK) cell activity, T cell function, and cytokine regulation.
These effects were particularly noted with PSK, Huaier granules, and Shiitake mycelia extract.
Quality of Life (QoL) Improvements:
14 studies found that mushroom supplementation led to reduced symptom burden, improved energy levels, and better overall well-being.
Benefits were particularly seen in patients undergoing chemotherapy.
Adverse Effects:
Some studies reported mild side effects (Grade 2 or lower), including nausea, vomiting, diarrhea, and muscle pain.
Study Limitations:
Many studies had small sample sizes and lacked randomized controlled trial (RCT) designs.
Only 1 study was conducted in the U.S., while most were in Japan (20 studies), China (9 studies), Taiwan (2 studies), Brazil (2 studies), South Korea (2 studies), and 1 each in Norway, Iraq, and Thailand.
More large-scale, high-quality clinical trials are needed to confirm efficacy and safety for routine use in cancer treatment.
Mechanistically, epidemiologically, and clinically, mushrooms show immense potential in both the prevention and treatment of cancer. Large-scale, high-quality clinical trials should be initiated to further assess the efficacy of mushrooms for cancer treatment. In the meantime, incorporating more mushrooms into your diet is a well-supported and proactive step that may help reduce cancer risk.

Cancer is caused by toxins and EMF radiation and there are already ways to deal with that.
When it comes to toxins, they need to be removed from the body via lymphatic cells, aka white blood cells, that are distributed throughout the body via the lymph system, which can get clogged and stop operating properly. 714X was invented by Gaston Naessens. This product is a powerful immune system modulator that cured 750 out of 1,000 cancer patients! This remedy is safe, without negative side effects. It’s manufactured in Canada and sold in eighty countries. It has also been used to cure AIDS and multiple sclerosis. Naessens explains how it revitalizes the immune system so the body can heal itself. The product is injected into a lower lymph node once a day for 21 days to unclog the lymph system which is as extensive as the circulatory system. Once the lymph is working, tumors, shrink and disappear.
For more information read, "The Persecution and Trial of Gaston Naessens" by Christopher Bird. Or check these links:

I found Bird’s book incredibly informative and eye-opening. The Canadian Medical Protective Association lied in the trial hoping to keep 714X off the market. Despite their lies, Naessens’ supporters showed up from around the world to testify on his behalf. The book also exposes how the medical industry places profit ahead of health. Most importantly it provides details of how 714X works, be sure to read the appendices.
On the other hand, when it comes to EMF radiation, the old theory that only ionizing radiation causes cancer has been debunked. The distinguished authors of an extensive peer reviewed meta analysis of over 1000 studies strongly emphasize that cell phones must be considered a class I carcinogen which means that cell phones are known to definitely cause cancer.
Here’s the article: https://ehjournal.biomedcentral.com/articles/10.1186/s12940-022-00900-9
Additionally, 256 EMF scientists from 44 nations signed a letter demanding that government agencies protect humans and all life from the terribly damaging effects of EMF’s which come mostly from cellphones due to their close proximity to the body.
Here’s the letter: https://emfscientist.org/
As we all know, cellphones are incredibly convenient and useful, but they are useless when you are dead. I only use mine for emergencies but keep it on Airplane mode or turned off 99.9% of the time.
As for WiFi which is also a problem, I use ethernet cables instead of WiFi.
Unfortunately greed has been working overtime to keep people sick so profits can be made. Despite that, our health in our greatest wealth.
Definitely eat mushrooms daily. All kinds. A great mushroom mix combination powder is available from Dr Fuhrman.
