What is tetralogy of Fallot? Tetralogy of Fallot (TOF) is a serious, congenital heart defect, affecting about two in 10,000 babies. In TOF, the abnormal connections prevent enough oxygen-poor (blue) blood from flowing to the lungs as it should. As a result, a person with TOF has a lower-than-normal amount of oxygen in the blood and typically, surgical correction is necessary.

Smoking can cause cancer and then block your body from fighting it: Poisons in cigarette smoke can weaken the bodyâs immune system, making it harder to kill cancer cells. When this happens, cancer cells keep growing without being stopped. Poisons in tobacco smoke can damage or change a cell's DNA. DNA is the cell's instruction manual that controls a cell's normal growth and function. When DNA is damaged, a cell can begin growing out of control and create a cancer tumor. Doctors have known for years that smoking causes most lung cancers.
