The effect of selected food phytochemicals on breast cancer metastasis based on in vivo capture of circulating tumor cells.

The number of circulating tumor cells (CTCs) in a mouse tumor model fed with different dietary factors was first evaluated by in vivo CTC capture at different time points of cancer progression. The results showed that the number of CTCs reflected the degree of cancer progression. A new assessment method of dietary factor effects on cancer metastasis was established.
