Can Artificial Intelligence Make Doctors Better?
This is a class room

for artificial intelligence, or AI.


Its teacher, Rishi Rawat is feeding the computer more samples

of cancer cells.


"So, they're like a computer brain,

and you can put the data into them

and they will learn the patterns

that's important for making decisions."


Decisions by doctors

to determine the best treatment

for their patients.


"Machines are not gonna take over the place of doctors.


Computers will not treat patients,

but they will help make certain decisions

and look for things

that the human brain can't recognize these patterns

by itself."


For examples,

once a cancerous tumor is removed

from a patient

with breast cancer,

the doctors still have to treat the patient

to reduce the risk of recurrence.


The type of treatment depends

on the type of cancer

and whether the tumor is driven by estrogen.


"So, what the pathologist has to do

is to count what percentage of the cells here are brown,

versus what percentage are not."


This process could take days or even longer.


The computer can do something

better than just count cells.


AI can recognize complicated patterns

on how the cells are arranged,

with the hope,

in the near future

of making a quick and more reliable diagnosis

that is free of human error.


"Are they disordered?


Are they in a regular spacing?


What's going on exactly

with the arrangement of the cells

in the tissue."


Scientists say

the time is ripe

for the marriage

between computer science and cancer research.


"All of a sudden,

we have the computing power

to really do it

in real time.


We have the ability of scanning a slide

to high enough resolution

so that the computer can see every little feature of the cancer.


So it's a convergence of technology.


We couldn't have done this.


We didn't have the computing power

to do this several years ago.

But now, it's all changed."


The research now is on breast cancer,

but doctors predict

artificial intelligence will eventually be used

to help treat patients

with all forms of cancer.
