Why a single lactate dehydrogenase result tells you very little — and how a pattern of LDH tests across time can show you whether your cancer is advancing, retreating, or holding steady.

A Snapshot vs. a Movie

A single LDH result is a snapshot. It tells you where the number sits today — and very little else.

A series of LDH results is something else entirely. It's a movie. It tells you which direction the metabolic engine of your cancer is moving. It tells you whether your tumor burden is climbing, plateauing, or shrinking. It tells you whether your current treatment — conventional, integrative, or both — is actually working at the cellular ...

The Hidden Skin Cancer Risk of Citrus and Sun Exposure

What grapefruit, limes, and lemons do to your skin — and why I follow the Six-Hour Rule before sunshine

Citrus fruits are celebrated for their vitamin C, flavonoids, and antioxidant power. But...

How to shop strategically, reduce pesticide exposure, and wash your produce the right way — including the evidence-based baking soda method.

If you or someone you love is navigating a cancer diagnosis, the food choices you make every single day matter. Not just in terms of nutrition, but in terms of what may be riding along on your produce when it arrives at your plate.

Every year, the Environmental Working Group (EWG) analyzes data from the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) to identify which fruits and vegetables carry the highest — and lowest — levels of pesticide residues. Their findings are published as two iconic lists: the Dirty Dozen™ and the Clean 15™.

At Prevail Over Cancer, we follow the principle: Prevail. Assess. Don't Guess.™ That means making informed decisions grounded in real data — including the data on what's sprayed on your food.

This guide will walk you through both lists, explain why pesticide exposure matters in t...

Broccoli Sprouts and Cancer: The Complete Science of Sulforaphane

If you add only one food to your anticancer nutrition plan, the research points strongly to one answer: broccoli sprouts. These tiny, unassuming seedlings — available at most grocery stores or easy to grow at home — contain concentrations of the most well-studied anticancer phytochemical on Earth.

That compound is sulforaphane (SFN) — an isothiocyanate derived from cruciferous vegetables that has now been investigated in over 3,000 published studies. And unlike many "superfoods" hyped on social media, sulforaphane's mechanisms are deeply understood at the molecular level, spanning cancer prevention, cancer stem cell targeting, chemotherapy enhancement, radiation sensitization, and immunotherapy support.

This research blog compiles everything the current science tells us about broccoli sprouts and cancer — including how sulforaphane works, how to maximize the amount you produce and absorb, and how it interacts with ...

Why Should We Consider Short-Term Fasting During Chemotherapy Treatments?

Short-term fasting (STF) has shown promise in enhancing the efficacy of cancer treatments while protecting healthy cells from toxicity. Studies suggest that STF can slow tumor growth and improve the quality of life for cancer patients.

Short-term fasting (STF) has shown promising effects on cancer cells in the human body, according to several medical journal references. Here are some key findings:

1. Differential Stress Resistance (DSR): STF protects healthy cells from the toxic effects of chemotherapy while making cancer cells more vulnerable to treatment. This is because healthy cells can enter a maintenance and repair mode during fasting, while cancer cells, which rely heavily on glucose, struggle to adapt.
2. Enhanced Chemotherapy Efficacy: Preclinica

Understanding fungal DNA in cancer tumors, terrain imbalances, antifungal foods, and how metabolism shapes fungal behavior in the body.

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and Founder of Prevail Over Cancer and the Prevail Protocol. 

 Why Fungi Are Being Found in Human Tumors

Large sequencing studies have confirmed that low-abundance fungal DNA and fungal cells appear across multiple cancer types — including breast, lung, GI, melanoma, and gynecologic tumors. These findings do not indicate infection and do not establish fungi as carcinogens. Instead, they highlight fungi as ecological participants within the tumor microenvironment.

• The Cell pan‑cancer analysis identified cancer‑type-specific fungal signatures, often co-occurring with distinct bacterial communities and immune phenotypes.
• A second Cell study confirmed the presence of fungi in GI and lung tumors and demonstrated associations with immune infiltration...

How pumpkin seeds support anticancer nutrition, key nutrients, research findings, and practical guidance. 

Research and written by Keith Bishop, Cancer Coach, Clinical Nutritionist, Retired Pharmacist, and Founder of Prevail Over Cancer™ and the Prevail Protocol™

Pumpkin seeds—often treated as a simple snack—are quietly becoming one of the most compelling foods in anticancer nutrition. Rich in bioactive compounds, antioxidants, lignans, and unique proteins, these seeds have demonstrated promising effects in laboratory studies and population research. Below is a comprehensive, evidence-based look at what we know so far.

Anticancer Actions of Pumpkin Seeds

Pumpkin Seed Apoptosis-Inducing Activity

Pumpkin seed protein fractions have been shown to induce apoptosis (programmed cell death) in cancer cells, including liver (HepG2) and triple-negative breast cancer (MDA-MB-231) cell lines.[i]

Antioxidant & Anti-Inflammatory Effects

Pumpkin seeds contain phenolic compounds, tocopherol...

The Anticancer Actions of IV Vitamin C: Mechanisms, Dosing, Safety Labs, and Integration with Oncology Care

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, and Founder of Prevail Over Cancer™, and the Prevail Protocol™

High-dose intravenous vitamin C (IVC) has reemerged as a promising adjunctive therapy in integrative oncology. Modern research highlights its unique pharmacology, potential anticancer mechanisms, and its ability to support patients undergoing chemotherapy, radiation, and immunotherapy. This guide breaks down the science, dosing considerations, safety labs, and clinical integration—supported by peer-reviewed medical literature.

What Makes IV Vitamin C Different From Oral Vitamin C?

Oral vitamin C absorption is tightly limited by intestinal transporters, which cap blood levels even at high doses. In contrast, IV administration bypasses intestinal absorption and produces blood concentrations 100–500× higher than those required for a...

Foods, supplements, and lifestyle habits that support your immune system’s interferon natural defense.

Researched and written by Keith Bishop, Integrative Cancer Educator, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and Founder of Prevail Over Cancer.

What Is Interferon?

Interferons are natural proteins your body makes to help fight infections and abnormal cells—including cancer. They act like messengers, telling your immune system to wake up, attack, and clean up. There are three main types:

• Type I (IFN-α and IFN-β): These help stop cancer cells from growing and spreading.
• Type II (IFN-γ): This type activates immune cells to recognize and destroy cancer cells.
• Type III (IFN-λ): Mostly helps protect surfaces like your skin and gut, with growing interest in cancer research.

Interferons are so powerful that some cancer treatments use them directly or try to boost their effects.[i]

Foods That May Help Your Body Make More Interferon

Cancer Cells Thrive on Glucose and L-Glutamine: Insights from Dr. Thomas Seyfried

Dr. Thomas Seyfried, PhD, has extensively researched how cancer cells depend on glucose and L-glutamine for their growth and proliferation. Cancer cells exhibit altered metabolism, relying heavily on glucose (the Warburg effect) and L-glutamine (an amino acid) to fuel their rapid division and growth. By disrupting these metabolic pathways, we can effectively starve cancer cells and inhibit their growth.
