Perhaps a better one would be. If the tests come back negative, the doctor removes both lungs and then just to make sure it hasn't spread he amputates all the limbs. Can't be too careful and it is best to make sure you remove all possibilities of danger. We wouldn't want Brandon firing them for incompetence.
You have given one of many possible scenarios, which, by itself, does not define the situation. Hypothetically, if there are indications that you may have a disease, and the truth can only be determined by a surgery which can fix the disease on the spot if it finds it, but which, in itself, does harm, whether the disease is present or not, sometimes it will be prudent to do the test surgery and sometimes it will not. In general, as I have argued before, the problem can be analyzed like this:
1. What is the probability that the disease is present based on what is known before doing the exploratory surgery?
2. If the disease is present, how negative are the consequences?
3. What are the negative consequences of the exploratory surgery?
One can construct a million specific examples. In some cases it will be wise to do the surgical test, even though it has consequences, and in some cases it will not. One thing that is sure, however, is that the mere fact that the surgery does not find the disease, does not, taken in a vacuum, indicate that the test was not the best course of action given what was known before it was done.
