(3) As a contradictory Process, practice has created a human world but also a heteromorphism world.

(4) Innocuousness tumor group have no manifest bleeding and necrosis. Cells have no heteromorphism and less caryocinesia.

(5) Malignancy tumor group are abundance of cellulars and haemorrhage, necrosis, heteromorphism are manifest.
