The cancer cells can be controlled with chemotherapy so the first one is definitely wrong. And I do not believe that they contain stem cells. The last one is right because the reason cells become cancerous is because their growth inhibitors are broken or switched off, so they do not know when to stop growing and it becomes a problem for the body.

Proteins act as what in cells to control reactions
Damm [24]

The answer is; catalyst

These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.
