Which one of the following is not a property of cancerous cells, whereas the remaining three are?
They compete with normal cells for vital nutrients
They do not remain confined in the area of formation
They divide in an uncontrolled manner
They show contact inhibition
Normal cells show a property called contact inhibition by virtue of which contact with other cells inhibits their uncontrolled growth. Cancer cells appear to have lost this property. As a result, they divide in an uncontrolled manner. Additionally, malignant tumors compete with normal cells for vital nutrients and do not remain confined, spreading to other parts of the body (metastasis).
