Pretty much. They don't do much normal stuff beyong replication and releasing hormones that stimulate capillary growth to keep them fed.

Ok thank you. So the procedure protocols can be disrupted by environmental influences eg. radiation poisoning, and by genetic, inheritable weaknesses in coding checking procedures? Why don’t the surrounding cells say ‘hey, you’re going crazy, stop!’?

A cancerous cell might develop a mutation that would reduce the amount of a protein on it's surface that would normally be recognized by immune cells trying to kill cancerous cells.
No two cancers are exactly alike on a genetic level, even though may have the same medical label. Each is a unique collection of many mutations that lead to a cell population that can replicate, invade, evade immune detection, etc.

They do. Our immune system works very hard to suppress cancerous and pre-cancerous cells all over our body. The ones that become deadly tumours are the ones that by chance are able to fly under the radar of the immune system. Natural selection.
