Can Artificial Intelligence Make Doctors Better?
Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.
Rishi Rawat teaches AI at the University of Southern California's (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast.
Rawat provides information about cancer cells to a computer. He says this data helps the machine learn.
"...You can put the data into them and they will learn the patterns and the pattern recognition that's important to making decisions."
David Agus is another USC researcher. He believes that "machines are not going to take 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."
Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells.
That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns, or structures, and learn how the cells are organized.
The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes.
"All of a sudden, we have the computing power to really do it in real time...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."
Agus adds that the process could be done "for almost no cost in the developing world." He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
The University of Southern California researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

make a difference 有影响；有关系
There's nothing I can say or do that's gonna make a difference here.
I want to do something, you know, make a difference.
人工智能技术可能很快会成为对医生们有用的工具 。它或许能帮助医生以前所未有的方式更好地了解和治疗乳腺癌等疾病 。
拉瓦特（Rishi Rawat）在南加州大学临床科学中心教授人工智能技术（AI），他还是研究人工智能和机器学习如何更容易诊断乳房癌变的科学团队的一员 。
大卫·阿古斯（David Agus）是南加州大学另一位研究员 。他认为，“机器无法取代医生 。”
一旦确诊的恶性肿瘤被切除，患者还必须接受能降低癌症复发风险的治疗 。治疗方案取决于癌症类型 。目前，研究人员会切取一块薄片组织，放在一块玻璃上，然后将其染色，以便更好地观察细胞 。
这一过程可能需要数天，甚至更长时间 。科学家们表示，人工智能的作用不仅仅只限于统计细胞 。通过机器学习，它可以识别复杂的图像或结构，并了解细胞是如何组成的 。
“我们突然间具备了能够做出实时诊断的计算能力 。我们本来难以实现这一成就，因为几年前我们不具备这种计算能力，而现在一切都变了 。”
阿古斯补充说，这个过程“在发展中国家几乎不需要任何成本” 。他说，拥有大量患者的信息对于机器有效地完成其医学工作来说非常重要 。
南加州大学的研究人员目前只研究乳腺癌 。但医生们预测，人工智能终有一日能对各种类型的癌症产生影响 。
