For many decades, scientists have been studying the effect of thyroid hormones in promoting cancer proliferation. Confusion and contradictions often arise in “cancer & thyroid” research reviews because the relationship between cancer and thyroid hormones is very complex. For example, a recent review of science since the 1940s attempted to reclassify research findings under poorly defined generalizations of “hypothyroidism,” “euthyroidism” or “hyperthyroidism” and variable “high T3” or “low T4” conditions (Krashin et al, 2019). Such reviews can muddy the science more than clarify it. Fortunately, Aleck Hercbergs and Paul J. Davis and colleagues have been at the forefront of research …
