A friend of mine's wife had breast cancer. She only had a month before she went for surgery.

I suggested she take 100k/day until surgery and for 30 days thereafter.

When she went for surgery the mass had shrunk 1 millimeter and encapsulated and was removed with no problem.

If there has been a bout with breast cancer or a family history of breast cancer, vitamin D levels should be kept around 85 ng/mL.
