The culture of biomedicine is the norms of the social and medical aspects of how we are treating patients. This is important because the culture of medicine is constantly changing and goes through stages. For example, medicalization in the early half of the 20th century focused on advertisement of diseases that were predominant during that time frame. For example, antibiotics were popular near the era of World War II and were highly advertised. As medicalization turned into biomedicalization, the focused turned to promoting drugs to simply make the body work better. One example would be advertising daily vitamins, and claiming that they will help you live longer.
I think that dichotomy simply came from the fact that things, especially in western society, are considered cut and dry one thing or another. For example, people tend to view wealth as being rich or poor, or hunger and hungry or not hungry. Western society seems to go for the truth and the truth rarely involves an intermediate choice. I think that dichotomy is a little ridiculous simply because it seems very narrow minded to think as something being one thing or another. In some instances, there is an intermediate between two things, such as a middle class which is ‘medium wealth’.
Dichotomy is excepted as true and logical because western society tends to search for the definite truth through the answers of science. Inconclusive evidence or intermediate answers are rarely seen in modern science therefore western society sees answers as being one way or another. This is the way western society views healthy individuals; either someone is healthy, or they are not healthy. It is rarely interpreted to where someone has cancer in one area of their body, but people still view them as healthy because the rest of their body is cancer free. Therefore, if someone has cancer they are simply considered ‘ill’.
