Lecture 8

Traditionally, doctors treat cancers by attacking individual cells. By identifying separate forms cancer cells without molecule test or gene sequencing, however, we can’t understand how the whole cancer system works. Thus the effect of this method is very limited.

Lecture 9

Mammography is the most common way to detect breast cancer. However, with the increase of breast density, it would be harder to find cancer through X-ray. Dr. Deborah Rhodes has developed a new tool for tumor detection, which is three times as effective as traditional mammograms. What’s more, it is cheaper than other technology. But her research was rejected for by journals, because it is so cheap that the producers of traditional mammograms won’t be happy to see it. Furthermore, there are also some political forces keeping it from the market. (91 words)
