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...

If your liver has already done the hard work of neutralizing a toxin or excess hormone — but your gut is quietly undoing all of that work before it can leave your body — you have an enzyme problem.

That enzyme is called beta-glucuronidase. And one of the most-researched natural compounds for addressing it is calcium D-glucarate.

In this post, we'll break down exactly what calcium D-glucarate is, how it works at the biochemical level, what the research shows across multiple cancer types, and where it fits inside a comprehensive integrative oncology protocol.

What Is Calcium D-Glucarate?

Calcium D-glucarate is the calcium salt of D-glucaric acid — a naturally occurring compound produced in small amounts by the human body and found abundantly in a variety of plant foods. The calcium is there for stability in supplement form. The active ingredient is the glucarate portion.

Glucaric a...

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 ...

The Evidence-Based Guide to Active Hexose Correlated Compound — How It Works, What Human Studies Show, and How to Use It Strategically With Cancer Treatment

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

If you’ve been diagnosed with cancer — or you’re supporting someone who has — you’ve probably heard about mushroom-based immune supplements. But not all mushroom extracts are created equal. AHCC (Active Hexose Correlated Compound) stands apart from the crowd, not because of marketing hype, but because of an unusually strong body of clinical research, including human trials published in peer-reviewed journals.

In this post, I’m going to walk you through exactly what AHCC is, where it comes from, how it differs from beta-glucan, what the laboratory and animal studies show, what human clinical studies have found, how it interacts with chemotherapy, rad...

How the Sunshine Hormone Reduces Cancer Risk, Activates Your Cancer-Fighting Immune System, and What Your Blood Test Number Actually Means

Introduction: The Overlooked Hormone That Fights Cancer

Vitamin D3 — widely known as the "sunshine vitamin" — is one of the most extensively researched nutrients in cancer science today. Yet despite decades of compelling evidence, vitamin D3 deficiency remains a global epidemic, with an estimated 1 billion people worldwide carrying insufficient levels. In the United States alone, studies suggest that up to 40% of adults are deficient.

What makes this alarming in the context of cancer is the growing body of peer-reviewed evidence showing that adequate vitamin D3 levels are associated with meaningfully lower cancer risk, better treatment outcomes, reduced cancer mortality, and a more robust...

A Peer-Reviewed Clinical Guide for Clinicians and Patients on Astaxanthin's Anticancer Mechanisms, Natural Sources, and Therapeutic Integration

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

Key Takeaways

• Astaxanthin (ASX) is a keto-carotenoid derived primarily from the microalga Haematococcus pluvialis and marine seafood, with antioxidant potency up to 100 times greater than vitamin E.
• Peer-reviewed research documents nine distinct anticancer mechanisms, including NF-κB suppression, Nrf2 activation, induction of apoptosis, STAT3 inhibition, and anti-metastatic activity.
• Preclinical evidence spans breast, colon, liver, prostate, lung, leukemia, melanoma, gastric, and oral cancers.
• Emerging 2024–2025 research identifies new mechanisms, including modulation of the gut microbiota and targeting of the USP39/β-catenin pathway in hepatocellular

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.

 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...
