Ralph Weichselbaum, who is today director of the Ludwig Center at Chicago, and Ludwig Board member Samuel Hellman suggested somewhat controversially in 1995 that metastatic cancer could occupy an intermediate state between curable, localized tumors and lethal, systemic disease. Twenty-three years later, Weichselbaum, Hellman and colleagues have confirmed their “oligometastasis” hypothesis with a molecular analysis of tumors from patients treated for colorectal cancer.
As Ludwig MIT’s director Bob Weinberg once said: “If you live long enough, you will get cancer.” But why is cancer the beast that stalks us all?

To understand this issue, we need to go way back in our evolutionary history.
