Not to oversimplify the complexities of cancer or anything, but for some reason, Peter Hintjens’ (creator of zeromq) suspicions about the primary cause of his own cancer came to mind after reading this [1].
”As for not getting cancer… the probable cause in my case was a parasite called a liver fluke, which attaches to the bile duct and produces carcinogens. Nature is nice like that. The parasite comes from farmed fresh-water fish. The cancer I had is a major cause of death in SE Asia. I think it was cheap sushi that almost killed me.”
