These are pretty big differences ... It's the first time that vitamin D has been linked to breast cancer progression.
We have no idea whether correcting a vitamin D deficiency will in any way alter these outcomes
We were concerned to find that vitamin D deficiency was so common in women diagnosed with breast cancer and that very low vitamin D levels adversely affected patient outcome
These data indicate an association between vitamin D and breast cancer outcome, but we can't say at this time if it is causal.
This study found that vitamin D deficiency is very common among women with breast cancer, and it suggests that vitamin D deficiency is linked to poorer outcomes in these women
