Grapefruits Cause Breast Cancer?

The New York Times investigates the claim that GRAPEFRUITS can INCREASE breast cancer risk—what the heck? More from Anahad O’Connor:
The British Journal of Cancer that found an increased risk of breast cancer among postmenopausal women who ate large amounts of grapefruit. In the group of women, more than 46,000 over all, those who ate about a half a grapefruit every other day had a 30 percent higher risk of breast cancer than those who ate none, even after other risk factors were taken into account…

…That analysis used data from the Nurses’ Health Study, which followed more than 77,000 women 30 to 55 over many years. The scientists looked at intake of both grapefruit and grapefruit juice and found no rise in breast cancer risk, either among women over all or among postmenopausal women.
I don’t know, but I have a hard time believing any fruit or vegetable causes cancer—what about you?

UPDATE: Here's what Dr. Fuhrman had to say:
This is not new. I have been advising women on not to consume too many grapefruits, not more than 2 weekly for the last year or so just to play it safe. The issue is a compound in grapefruit that interferes with the breakdown of estrogen. Whereas green vegetables aid in the breakdown of estrogen for easy excretion of excess by the body.

yeeeeeeeah...fruit causing cancer? don't think so...i mean really...

these women were older (therefore more likely to get breast cancer)...and who knows how many yrs they had been on birth control pills (known to increase risk) or any other medicine that's been proven to increase the risk of getting that type of cancer...c'mon...

fruit?? and grapefruit, especially...that's just crazy talk

Dr. Fuhrman has limited his grapefruit recommendations. So, perhaps, there is reason for caution.

What is Dr. F.'s response to this particular study?
