Which statement best describes cancer cells?
• They grow as a single layer of cells.
• They cease to reproduce after 20-50 mitotic divisions.
• They reproduce only when needed to replace missing cells.
• They are not regulated by contact inhibition.

The lack of contact inhibition control in cancer cells is what allows them to continue to reproduce. In non-cancerous cells, contact inhibition triggers cells to stop dividing and to grow when they come in contact with other cells. This control is lost when cells undergo malignant transformation.
