Comparing VEGF/VEGFR subunit expressions among thyroid cancer and other cancer types, the result clearly showed that the mean log2 fluorescence intensity of VEGFC was 9.08 ± 0.71 in thyroid cancers and 6.66 ± 0.084 in other cancer types (5.33‐fold, P = 0.002). The gene discussed is VEGFA; the disease is thyroid cancer.
