From Glucose and Ketones to Genetics and Toxins—Why Testing Beats Guessing in Cancer Prevention and Metabolic Therapy

Written and researched by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and founder of Prevail Over Cancer

What if the most dangerous cancer risks aren’t visible on a scan or felt in the body—but quietly building in your blood, urine, and genes?

In cancer care, guessing is gambling. Symptoms can be vague, and even “clean” imaging doesn’t mean the terrain is safe. That’s why lab testing isn’t just helpful—it’s essential. From glucose and ketones to hormone metabolites and heavy metals, these biomarkers reveal the biochemical landscape cancer cells exploit—and the ones we can disrupt.

Whether you're navigating active treatment, remission, or prevention, here’s a breakdown of the tests I recommend most often for clients—and why they matter.

The following tests are part of what I help clients with and are not a comprehensive list. It is essenti...

1. Introduction

• Brief overview of the topic
• Importance of understanding the impact of toxic metals on cancer risk

1. Toxic Metals and Their Carcinogenic Effects

• Definition of toxic metals
• Common toxic metals associated with cancer risk: Lead (Pb), Chromium (Cr), Arsenic (As), Cadmium (Cd), Nickel (Ni), Mercury (Hg)
• Mechanisms of carcinogenicity

• Hair Test: Long-term exposure detection
• Urine Test: Recent exposure detection
• Blood Test: Current exposure detection
• Procedure and interpretation of results
• ZRT – blood and urine test
• Mo
