Cell death: Malignant tumors have various types of death. Comedonecrosis is a cell death in the middle of the tumor (due to outgrowing its blood supply). Dengeration just means it has died, but in general due to senescence (just old age). Tumor necrosis is usually something seen in malignant tumors, while degeneration is usually associated with benign tumors.

How they act: Malignant tumors can grow locally and destroy other tissues but can also spread distantly. Benign tumors can grow locally and can cause symptoms if they enlarge but do not spread to distant organs. Hope this helps.
