Higher plasma vascular endothelial growth factor levels correlate with menopause, overexpression of p53, and recurrence of breast cancer.

Purpose Vascular endothelial growth factor (VEGF) is an important factor involved in angiogenesis. Many studies have reported that the expression of VEGF in breast cancer is an unfavorable prognostic factor. However, there are few studies that have analyzed blood VEGF levels because most used serum VEGF, generally thought to originate from platelets. We measured plasma VEGF levels, which evaluate the level of tumor-derived VEGF, in various breast diseases.
