It's to do with which cellular processes have been turned on and off and what their effects are. Any cellular process that allows for accelerated unlimited replication, invasion, tissue destruction, metastatic spread etc. will generally lead to a malignant tumour.
And where you have abnormal cells which haven't acquired any of those features of malignancy, then that's a benign tumour.

At a cellular level there are heaps and heaps of different molecules and messengers that can be switched on or off to give those effects just in the cell cycle alone to control replication.
