Found it. Of course, this is just one study, but the results are pretty stout, so interesting none the less:
"We hypothesized that inadequate Mg levels, perhaps relative to Ca levels (e.g. a high Ca/Mg ratio) are associated with greater prostate cancer risk. ........................
Results: Serum Mg levels were significantly lower, while the Ca/Mg ratio was significantly higher, among high-grade cases vs. controls (p = 0.04, p = 0.01, respectively)
. Elevated Mg was significantly associated with a lower risk of high-grade prostate cancer (OR = 0.26
(0.09, 0.85)). An elevated Ca/Mg ratio was also associated with an increased risk of high-grade prostate cancer (OR = 2.81
(1.24, 6.36) adjusted for serum Ca and Mg). In contrast, blood Ca levels were not significantly associated with prostate cancer or PIN.Mg, Ca, or Ca/Mg levels were not associated with low-grade cancer, PIN, PSA levels, prostate volume, or BPH treatment.Conclusion: Low blood Mg levels and a high Ca/Mg ratio were significantly associated with high-grade prostate cancer.
These findings suggest Mg affects prostate cancer risk perhaps through interacting with Ca. "https://pubmed.ncbi.nlm.nih.gov/21541018/
