How fast do lung cancer cells reproduce and how fast do non cancerous cells reproduce?

As a general rule, non-cancerous cells divide faster than malignant cells, but they stop dividing when they contact other cells (known as contact inhibition). Malignant cells, on the other hand, never stop dividing and eventually break away from the original tumor site and spread (metastasize) to other organs in the body.
