I was just reading my Mamm mag this afternoon and saw a research brief that was interesting. For those that do not get Mamm I have added the brief.
"Progress in preventing bone metastases. Advanced breast cancer often
spreads to the bones, and now scientists at the University of Michigan might know why. They discovered over-production of a certain type of protein, called nuclear factor-kappa B, in breast cancer cells.
The protein is believed to play a role in stimulating tumor growth, especially in bone, and it could become a potential target for treating breast cancer and preventing bone metastasis, scientiset say."
