"Sugar in western diets increases risk for breast cancer tumors and metastasis"
"The high amounts of dietary sugar in the typical Western diet may increase the risk of breast cancer and metastasis to the lungs, according to a study at The University of Texas MD Anderson Cancer Center. "

What's this got to do with Omega 3 and 6 is probably your first thought.
A pathway increased by sugar is the expression of an enzyme called LOX12, which is an enzyme that is one of the key pathways by which plant based Omega 6 linoleic acid and the longer chain arachidonic acid are converted to downstream oxidized products that are highly bio-active including 12HETE, which has roles in controlling cell growth and invasion.

The pathways are multiple and complex, and much remains to be determined, but several oxidized products of Omega 6s are associated with increased risks of cancer by multiple mechanisms.
So here it appears we have a cross amplification of relevant pathways by excess sugar and Omega 6s in the diet.
I see Lani has also posted the story. http://her2support.org/vbulletin/showthread.php?t=64352
This emphases how interlinked things are and that approaches need to be holistic.
