When they say cancer is a disorder of the growth of a cell...?

Question

do they mean, they divide uncontrollably or the cell keeps growing without dividing?

Answer 1

Divide uncontrollably. This is why cancer shows up in the form of tumours of cancerous cells.

When cancer metastasizes one or a group of the cells break off the main tumour and can start growing elsewhere in the body and this is what usually kills is because you end up haveing cancer all over the body.

Answer 2

Divide uncontrollably

Answer 3

Cancer cells have defects in the cell cycle regulaory functions, the cell cycle has checkpoints to monitor growth factors, development, check DNA and chromosomes for defects. Normal cells move meticulously through the cell cycle checkpoints and they develop normally with minimal defects. In addition it has been proven that cancerous cells will continue to develop without anchorage media in a culture. This is a trait we have adapted because of the need for the cellular exoskeleton. So, cancer cells will grow without being connected to the exoskeleton just by being connected to other cancer cells, another defect in the cell cycle.

Answer 4

they mean divides uncontrollaby it divides before the cell is ready to be divided and continues on it bypasses all the enzymes that try to stop it from happening
