ELI5: How close are we to curing cancer as a fundamental illness?
gpt
You can read "The emperor of all maladies" to get an idea about the development in medical science re cancer. Out of 1000's of different types of cancer, we can fully cure 2-3 types; however, we are able to lengthen the life of pretty much any and every patient with cancer, so there is some progress. Out understanding about cancer is primitive, we cut it (surgery), burn it (radiation), or poison it (chemotherapy). All three treatments do harm to good sells along with cancer cells. In short, our most advanced medical treatment consists of killing cancer cells before we kill our patients; unfortunately, we often do kill our patients.
