We often use the word "cancer" as a metaphor for society's greatest ills, for deep-seated perils invisible to the naked eye. But what of cancer itself? If you know where to look, so-called "cancer clusters" are as pervasive and permeative in vulnerable populations as the tumors of poverty, classism, environmental injustice, racism, corruption, etc...The evils are cumulative, just like the toxins that are silently spreading into our watersheds, ecosystems, food chains, blood streams, and bloodlines. In this long-overdue biopsy, Arsenault blends investigative journalism, personal narrative, memoir, history, scientific research, and political commentary in a haunting diagnosis of our malignant future.
