I'm aware of that. I also noted that they mention multiple cancers are not unlikely over time (I'm unable to access the article at this time so I can't quote directly), and they specifically pick the $5M figure as a value that they are uncertain about. I'm suggesting that $5M is probably a reasonable figure to remove any uncertainty.
