Dumbest thing I've ever heard.
Doctors don't use calculus.
You sir are an idiot. Doctors that specialize in diseases know that bacteria mulitply at an exponential rate. Doctors who study epidemiology uses TONS of calculus.

Calculating Breast Cancer Survival Rates

Subject: Finding roots
How do I find the nth year survival:
Survival of a group of breast cancer patients is 100 at year 0, 100*X
at year 1, 100*X*X at year 2, 100*X*X*X at year three and so on to
year 10.
For instance for a n = 10 year survival of 40% the value of X = 0.912
Where X is percentage survival, assuming survival decreases constantly
on a yearly basis. I would like to know how to solve for X for any
10-year survival from 1 to 100% survival at 10 years.
n is the year from 1->10 years
Anything involving rates involves calculus
1) Neurologists who take EEGs (electro-encephalograms) are measuring
brain voltages at various points in the brain to detect how the
voltages surge around. There's normal wave motion, as well as all sorts
of types of epilepsy and other problems that can be detected by this
method. Unfortunately, the data, as they come out of the machine, are
pretty noisy. Various mathematical "filters" must be applied to see the
underlying wave phenomena. This is basically Fourier analysis on wave
forms that shows how the geometry of the complex, noisy forms is
composed of stong, underlying primitive waves.
"My wife is a physician, a neurologist working with patients with
epilepsy. Every day she runs EEGs on the patients, where you hook
electrodes to the heads and plot the (microscopic) voltage differences
between various parts of the brain. If there are irregularities (caused
by tumors, lesions, et cetera), there are irregularities in the
electrical signals. She needs to take sums or differences of the
voltages, and can apply various digital filters to the data to
eliminate noise, or to eliminate a known signal from the rest to see if
there are irregularities in what's left. The frequencies of the signals
are interesting, but they come in a horrible mix, so the filters
effectively do various mathematical transforms to the signals, such as
Fourier transforms and many others. It's basically digital signal
processing, but with 20 signals, all of which are related."
"What is nuclear medicine?
Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials, or radiopharmaceuticals, to examine organ function and structure. Nuclear medicine imaging is a combination of many different disciplines, including chemistry, physics, mathematics, computer technology, and medicine. This branch of radiology is often used to help diagnose and treat abnormalities very early in the progression of a disease, such as thyroid cancer."
Next time think before you speak.
