Adjuvant Temperature Effects in Cancer Therapy
J. B. Block, C. G. Zubrod · 1973
Temperature-based cancer therapy research from 1973 demonstrates how energy applications can alter cellular processes and tumor behavior.
Plain English Summary
This 1973 review by Block examined how temperature changes (both heating and cooling) could be used alongside traditional cancer treatments to improve outcomes. The research explored hyperthermia (heating) and hypothermia (cooling) as adjuvant therapies, investigating how temperature affects tumor regression and cell cycle processes in cancer treatment.
Why This Matters
While this study predates modern EMF research by decades, it established crucial groundwork for understanding how energy-based therapies affect cellular processes in cancer treatment. The science demonstrates that external energy applications can significantly alter biological systems at the cellular level. What makes this relevant today is that radiofrequency and microwave EMF exposures also deposit energy into tissues, creating localized heating effects. The reality is that if controlled temperature changes can influence cell cycles and tumor behavior as therapeutic tools, then uncontrolled heating from wireless devices raises legitimate questions about biological effects. You don't have to accept that all energy exposures are harmless just because some are used therapeutically. The evidence shows we need rigorous safety standards for all forms of energy that interact with living tissue.

It is defensible to ask, given the large body of data needed to evaluate heat or cold as a potential adjunct to cancer therapy, whether the clinical data to date encourage obtaining such experimental information with the permutations of cytotoxic agent, temperature, normal tissue, and tumor tissue. The clinical and animal studies using a 'temperature gradient' approach are listed in table 3. While heat therapy may become of clinical importance in selected patients with accessible or superficial tumors, the approach remains trivial when one considers the more prevalent problem of disseminated cancer. Techniques and models are at hand to test the approach for systemic cancer with the view that existing temperature gradients may be manipulated toward therapeutic gain. Cold may play its greatest role in manipulating with safety temperature gradients between such disseminated tumors and normal tissues and provide thereby an expanded therapeutic ratio for the toxic effects of anticancer agents on normal tissue as compared with cancers.
