I have myeloma and am starting a course of revlimid (lenalidomide) & dexamethazone. Haematologist wants to do a VEGF test. What is it for?

Progression of MM. Based on Some studies, serum levels of VEGF are elevated in MM and and also dependent on severity of MM. Measuring VEGF may be useful in assessing disease progression and assessing response to chemotherapy. VEGF stands for vascular endothelial growth factor are substances secreted by the body that stimulate tumor growth.
