Analysis examines a subject by evaluating one of its aspects-- weighing evidence and possible causal linkages. It resembles other forms of paragraph development, especially classification and division. The object of analysis, however, is to get to the center of how something works. The following paragraph considers the link between cancer, poverty, and stress.
One possible explanation for these statistics on cancer can
be found in the high levels of stress associated with poverty.
Studies have found that stress can dampen the immune system, the
body's first line of defense against cancer, and experiments with
animals have shown that a stressful environment can enhance the
growth of a variety of tumors. The link between poverty, stress,
and cancer mortality in humans has not been proven, but studies
have shown a link between stress and other illnesses.
