人的手掌腳掌是不是不太容易有痣？

Sep 23rd 2013, 07:24

痣的全名為「黑色素細胞母斑」
除少數的痣是天生就有的，隨著年齡漸增，痣也會愈來愈多！有很多朋友會問，長痣是不是因為醬油、咖啡喝多了，或是太陽曬多了，還是身體器官健康出現了警訊？其實，長痣和這些都沒有什麼關係，主要是體質的問題。
黑色素痣主要是因為皮膚內有痣細胞增生，並且產生黑色素所致。存在皮膚的層面，可能在真皮層、或真皮層與表皮層的交界處。

另外，白種人膚色白皙較怕曬，臉、後背及小腿等易曬傷部位，出現皮膚癌變機率較高；台灣人膚色中等偏黑，黑色素瘤較易出現在手腳，日曬部位反倒不高，因此，手掌腳掌上的黑痣較需留意，癌變機率相對高。
