The statement that best describes cancer cells is,

_________________________

they are not regulated by contact inhibition".

Cancer is a fatal disease which includes the uncontrollable increase of cancer cells.

These cancerous cells reproduce at abnormal rates.

There are various kinds of cancer like breast cancer, ovarian cancer, skin cancer and so on.

That would be D.

Cancer cells are not regulated by contact inhibition.

They do not stop dividing when a single layer of cells is made and form clumps of cells(tumors). They divide(mitotically) several times and have lost control of their cell cycle.
