Vitamin D does not seem to affect the level of 5-AR, but it increases aromatase in bone cancer, ovarian cancer, and prostate cancer cells, and decreases aromatase in breast cancer cells and fat cells. No effect on aromatase in healthy ovarian cells. This could be why D is so protective against breast cancer but doesn't seem to affect prostate cancer risk at all. The aromatase elevation could cancel out D's anti-cancer effects.
