Cancer cells have a binary identity - one originating from outside immune cells like macrophages, making them non-self. Cancer cells have accumulated so many mutations that their group identity wants to live exceptionally and irregularly, transferred from outside. The main point is that cancer cells depend on inadequate energy, which increases mutations. Malignancy occurs with increasing mutations due to low energy. Benign conditions are possible with high energy and low mutations. Cancer cells are selfish, parasitic, irregular, immortal and immature due to their transferred mutated group identity from outside. Normal DNA sequences cannot be transcribed or expressed due to inadequate energy.
