WebTumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don't work properly, cells can grow out of control, which can lead to cancer. A tumor suppressor gene is like the brake pedal on a car. WebThis can cause cells that should be resting to divide and grow out of control, which can lead to cancer. 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.
