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...

Understanding Copper's Dual Role in Our Bodies and Its Link to Cancer

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

The Benefits and Needs of Copper:

Copper is essential in the human body. Copper is a vital trace mineral necessary for survival. It plays a crucial role in forming red blood cells, maintaining nerve cells, and supporting the immune system. It also aids in the absorption of iron and the development of healthy connective tissue. However, like many things, balance is key.

Copper is essential for cardiovascular health, bone strength, and aiding antioxidant defenses. Copper is integral in various enzymatic reactions and energy production within mitochondria.

High Levels of Copper and Cancer Risk:

Excessive copper can lead to oxidative stress and DNA damage, potentially increasing the risk of cancer development. Copper plays a significant role in this process due to its involvement in redox reactions, which are chemical reactions tha...
