What Can Cancer Cells Develop Into (2023)

1. How cancer starts, grows and spreads

  • Our bodies are made up of trillions of cells grouped to form tissues and organs. Genes inside the nucleus of each cell tell it when to grow, work, divide and die. Normally, our cells follow these instructions and we stay healthy. But when there is a change in our DNA or damage to it, a gene can mutate. Mutated genes don't work properly because the instructions in their DNA get mixed up. This can cause cells that should be resting to divide and grow out of control, which can lead to cancer.

  • The fundamental abnormality resulting in the development of cancer is the continual unregulated proliferation of cancer cells. Rather than responding appropriately to the signals that control normal cell behavior, cancer cells grow and divide in an uncontrolled manner, invading normal tissues and organs and eventually spreading throughout the body. The generalized loss of growth control exhibited by cancer cells is the net result of accumulated abnormalities in multiple cell regulatory systems and is reflected in several aspects of cell behavior that distinguish cancer cells from their normal counterparts.

  • At its heart, cancer is the result of uncontrolled cell growth. Our bodies are composed of trillions of cells, all working together. In cancer, one of those cells stops paying attention to the normal signals that tell cells to grow, stop growing or even to die. Cancer cells still share many of the same needs and properties of normal cells but they become independent of the controls that make our body function smoothly. The process by which a normal cell changes into one that behaves so abnormally can take a long time and is often triggered by outside influences.1  The next few sections describe the differences between normal and cancer cells and outline the steps leading to the creation of a cancer cell from a normal cell.
