    because cancer cells are genetically different from all of the other cells of the body
    because cancer cells are more resistant to toxins than normal cells
    because cancer cells started as normal body cells that then lost control of cell division, so they are very hard to distinguish from healthy body cells
    None of the answers is correct.
