Final answer:
A cell that loses its normal properties and becomes endangered of turning into a cancer cell is called a pre-cancerous or dysplastic cell.
Step-by-step explanation:
A cell is called pre-cancerous or dysplastic when it loses its normal properties and is at risk of becoming a cancer cell. This process occurs when the control over the cell cycle is compromised, typically due to DNA damage. Cells may rapidly divide and often lose the ability to differentiate into the appropriate cell type for their location in the body. They can become endangered of becoming a cancer cell.
Damage to cellular DNA can be caused by exposure to hazards like radiation or toxic chemicals. If these pre-cancerous cells evade the immune system, they can begin to proliferate, potentially forming a mass of abnormal cells known as a tumor. When cells become cancerous, they form tumors that grow uncontrollably, taking up nutrients and space needed by healthy cells, and ultimately causing tissue and organ damage.
