D-mannose, a simple sugar, has been studied for its potential anti-cancer actions. Below, we explore its mechanisms, effects on cancer treatments, and considerations for its use based on scientific research. Mannose cancer research is in the early stages and is limited to laboratory cancer cell studies, a few animal studies, and even fewer human studies.

The Warburg Cancer Effect and D-Mannose

The Warburg effect is a phenomenon in which cancer cells rely heavily on glycolysis (glucose) for energy production, even in the presence of oxygen. Research indicates that D-mannose can disrupt glycolysis, affecting the Warburg effect and reducing cancer cell proliferation. A study published in Nature Nature link shows how D-mannose interferes with glucose metabolism, impairing tumor growth.

My wife and I come from families with histories of cancer and dementia, and I was personally diagnosed with rheumatoid arthritis. As a teenager with acne, I took powerful antibiotics for years that contributed to loose stools. As I shifted my focus from traditional pharmacy to natural health and cancer support, I uncovered the crucial role of digestive health in tackling these health challenges. Since prioritizing my gut health, I’ve experienced a significant reduction in autoimmune aches and pains and tested negative for rheumatoid arthritis, transforming my overall well-being.

The gut microbiome, a vast ecosystem of trillions of microorganisms in our digestive tract, is emerging as a key player in cancer, health, and disease. Its influence extends beyond digestion, impacting immune function, mental health, and cancer prevention and treatment. Here's how this microscopic community can...

Melatonin in Cancer Protocols: Promise, Precaution, and the Latest Research

Researched and written by Keith Bishop, Integrative Cancer Educator, Clinical Nutritionist, Cancer Coach, and Retired Pharmacist

Melatonin, often called the "sleep hormone," is a naturally occurring compound produced by the pineal gland in the brain. While its primary role is to regulate the sleep-wake cycle, emerging research has revealed its potential as a potent anticancer agent. This blog explores melatonin's anticancer properties, additional health benefits, potential side effects, role in cancer treatment, recommended dosages, and possible drug interactions.

What is Melatonin?

Melatonin is a hormone that helps regulate circadian rhythms, ensuring a healthy sleep-wake cycle. It is also a potent antioxidant, capable of neutralizing free radicals and reducing oxidative stress, which are key contributors to cellular damage and aging.

Melatonin Anticancer Activity*

Research has shown that melatonin exhib...

Citrus fruits are celebrated for their health benefits, but did you know they might pose a hidden risk when combined with sun exposure? Recent studies have raised concerns about certain compounds in citrus fruits that could increase the risk of skin cancer. Here's what you need to know to stay safe while enjoying the sunshine.

The Cancer Culprit: Psoralens and Furocoumarins

Citrus fruits, such as oranges, lemons, limes, and grapefruits, contain naturally occurring compounds called psoralens and furocoumarins. These compounds are known as photocarcinogens, meaning they can interact with sun ultraviolet (UV) radiation to cause DNA damage in skin cells. This damage may increase the risk of developing skin cancers, including basal cell carcinoma (BCC)[i] [ii]  [iii], squamous cell carcinoma (SCC),[iv] and melanoma.[v] One population study found one serving per day of an increase in total citr...

Breaking Ground in Cancer Research: Ivermectin Cancer Potential Revealed!

Notice: This information is intended for educational purposes only and should not be used as a substitute for professional medical advice, diagnosis, or treatment. Always consult with your healthcare team before considering the integration of ivermectin or any other therapy into your health program to ensure it aligns with your specific medical needs and circumstances.

Ivermectin History

Ivermectin is a medication primarily used to treat parasitic infections. It was initially developed in the 1970s for veterinary use but was later approved for human use in the 1980s. In humans, ivermectin is prescribed for conditions such as strongyloidiasis (intestinal infection caused by threadworms) and onchocerciasis (river blindness). It is also used topically to treat head lice and skin conditions like rosacea.

Quercetin is a plant-derived flavonol found in many fruits, vegetables, and herbs. Known for its potent antioxidant, anti-inflammatory, antihistamine, and anticancer properties, it’s emerging as a key player in integrative oncology and immune modulation.

If you’re navigating cancer—whether newly diagnosed, in treatment, or in recovery—you’ve likely heard about antioxidants and immune support. But one compound stands out: quercetin, a flavonoid found in everyday foods like onions, apples, and broccoli. Emerging research suggests quercetin may help regulate inflammation, stabilize histamine levels, and even influence cancer-related pathways like apoptosis and angiogenesis. In this...

Boswellia serrata, or frankincense, has been used in traditional medicine for centuries. Recent studies have shown promising anticancer effects, making it a potential natural treatment for cancer.

Health Benefits of Boswellia

Boswellia offers a range of health benefits beyond its anticancer properties. Its potent anti-inflammatory effects make it helpful in treating conditions such as arthritis, inflammatory bowel disease (IBD), and asthma. Additionally, Boswellia can help reduce pain and improve respiratory health.[i]

Boswellia Anticancer  Ingredients and Mechanisms

Boswellia's anticancer properties are primarily attributed to its active compounds, boswellic acids. These compounds inhibit the production of leukotrienes, molecules that contribute to inflammation and t...

Cancer cells can remarkably manipulate their environment to support their growth and spread. One key component of this environment is collagen, a significant protein in the extracellular matrix (ECM). Collagen provides structural support and is crucial in cancer progression and metastasis.

I want to share my concerns since collagen peptide protein powders are popular. 

Collagen peptide proteins, derived from enzymatic hydrolysis of collagen, provide high doses of type I and III collagen. These collagens are particularly significant in cancer progression, as they contribute to the structural integrity and stiffness of the tumor microenvironment. Cancer cells can exploit these collagen-rich environments to enhance their adhesion, migration, and invasion capabilities, promoting tumor growth and metastasis. Studies have shown that cancer cells can utilize collagen peptides to create a protective extrace...

Learn about the anti-cancer benefits of Cannabigerolic acid (CBGa), a non-psychoactive cannabinoid found in the cannabis plant.

Written by Keith Bishop, Clinical Nutritionist, Cancer Coach, and Retired Pharmacist

The world of health and wellness is continually evolving, with new research and discoveries coming to light regularly. One such breakthrough is the potential anti-cancer benefits of Cannabigerolic acid (CBGa), a non-psychoactive cannabinoid found in the cannabis plant. This blog post explores the potential benefits of CBGa, its sources, and possible concerns and side effects, all backed by medical journal references.

Understanding CBGa

CBGa, often called the "mother of all cannabinoids," is the precursor from which other cannabinoids are made in the plant. It's sourced from the cannabis plant, specifically from young, immature plants. CBGa is non-psychoactive, meaning it won't cause the "high" associated with cannabis use. Its previous research has been hampered because t...
