Sample text

A sufficient cause is a cause that is always followed by the disease, but the disease may have other causes as well: D E We have only few such examples, but a lack of iron or vitamin B in the diet (E) and anemia (D) could be such causes. A necessary and sufficient cause is illustrated by E→D and here examples are few, if any. An exception might be single-gene disorders where the disease almost always follows the presence of the “mutation” like for PKU, cystic fibrosis, or sickle cell disease. In fact, most of the causes we study seem to follow a pattern like this: E D Sometimes D follows E, but not always, and sometimes D is seen for people not exposed to E.

Our common sense concept of causation will tell us that given all these conditions are in place the light will be on when we press the switch. Although there is a sequence of causes, the sequence is deterministic. If the electrician we asked to repair the light said the light did not work because of bad luck we would call another electrician. In disease causation we do not have many examples of sequences of a deterministic link between the exposures and the disease. Whether there is a random element in disease causation or not is not known and may never be known because J.

We can tell the smoker that his average lifetime risk is 10% for getting lung cancer. If a smoker has a family history of lung cancer or if he is also exposed to air pollution or asbestos his risk is higher. Certain genetic factors will also put him at a higher risk, but the risk will still be far from 1. 4 Causes of Diseases 27 Many smokers will live long lives and die from other causes than lung cancer. This is well in concordance with the fact that smoking causes lung cancer but only conditionally with other component causes or that the induction and latency time period may be longer than for other causes that lead to death.
