16 為甚麼心臟不會生癌？
/ O/ f6 n  U: E1 h. P8 a5.39.217.77:8898胃、肝、大腸、睪丸都會生癌，但為甚麼沒聽過有心臟癌呢？原因在於心臟以外的細胞都具有增殖機能，即使受了傷，只要過一段時間就能痊癒，這是因為細胞增殖使傷口癒合，然而心臟的細胞並不會增殖。癌細胞會持續增殖，接著破壞周圍的組織，就是因為心臟細胞不會增殖的關係，所以癌細胞是無法侵襲心臟。公仔箱論壇: c. P! g  g  [6 j* l

in fact, the heart is made of muscle, so it can develop cancer too, normally is the cardiac muscle itself, if it's benign, it's called myxoma; if it's malignant, it's called angisarcoma
