In cancer, VEGF‐B promotes tumour progression and metastasis.[7, 8, 9] A VEGF‐B α1 helix derivative was able to interact with both VEGFR1 and VEGFR2 implicating the region‘s potential role in angiogenesis and tumour growth.[10] Recently, VEGF‐B has been proposed as a possible biomarker in breast cancer diagnosis.[11]. This evidence concerns the gene VEGFB and breast cancer.
