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...

A Comprehensive Review of the anti-cancer actions of iodine.

Researched and written by Keith Bishop, clinical nutritionist, cancer coach, and retired pharmacist.

Iodine, an essential trace element, has garnered significant attention for its potential anticancer properties. This blog post delves into iodine's anticancer activity, its mechanisms, other health benefits, cancers at higher risk due to deficiency, interactions with medications, top food sources, potential side effects of excess iodine, testing methods, and supplement sources.

Anticancer Activity of Iodine

Research has shown that iodine exhibits significant anticancer effects, particularly in breast cancer. Molecular iodine has been found to diminish proliferation and invasive potential and activate the immune response in mammary cancer xenografts. Iodine induces apoptosis (programmed cell death) and inhibits angiogenesis (formation of new blo...
