Answer:

They are not regulated by contact inhibition.

Explanation:

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.
