I happened to run in to a Doctor buddy of mine this past weekend who shared with me some interesting info about Lavender Oil. There is a compound in Lavender Oil, Perillyl Alcohol, that acts as chemotherapy on around 80% of breast cancers. Rumor has it that some ladies use the Lavender Oil topically to the breast to prevent breast cancers.
Another preventive measure is to take enough Vitamin D to get your 25-(OH)-D blood level to somewhere between 60 and 100 ng/ml. By some it is estimated that a woman who does NOT have this "Vitamin D level" is at a 5 times higher risk for breast cancer.
And, remember, fibrocystic breasts are most likely Iodine deficient breasts!
