## The Doctors

The Doctors use mathematics constantly in their practice of
medicine. It ranges from modeling and proof to conversions and
basic arithmetic.

The most important aspect of mathematics that the doctors use
is modeling. Patients come to see the doctor with symptoms, variables.
Symptoms are not particular to one disease. So, for example, an
upset stomach does not mean that a person has ulcers. It is one
possibility, but not a constant. These symptoms then lead the
doctor to ask certain questions about the symptoms. Which might
lead the doctor to the answer or to call for tests or to more
questions. This process continues until the doctor is able to
logically work his way through the model and diagnose the patients
problem. The diagnosis leads to treatment and hopefully to a cure.
A doctor must be an expert at this or else he might treat the
patient incorrectly. This could lead to death and possible malpractice
lawsuits against the doctor.

Second, the doctor must be able to prove that the diagnosis
is correct to himself and to the patient. The doctor must be able
to logically show the patient that his diagnosis is correct. Most
patients will not allow costly and invsasive treatments to be
done just because the doctor wants to do the treatments. The doctor
must be able to prove to the patient that the diagnosis is correct
and that the treatment is required.

Finally, the doctor will also do routine arithmetic on a daily
basis. This could be as simple as converting grams to milligrams
for a prescription. This could also be a complex conversion where
the dosage of a medication is determined by weight. Here again,
mathematics comes into play.

So we have now seen that every one at the oncology offices
uses mathematics on a daily basis. Math is involved in every one's
life on a daily basis. So, the better a person is at math, the
better he/she can do her job.
