My kid could get a bad X-ray and I could get a call from the doctor saying I have something growing in my bum and that would change my perspective on everything instantaneously, on what is and what is not important.

Hanks is underscoring how quickly everyday priorities can be reordered by a sudden health crisis—either a child’s alarming diagnosis or his own. The deliberately blunt, even comic phrasing (“something growing in my bum”) heightens the shock value and emphasizes the body’s power to puncture ego, ambition, and trivial concerns. The quote frames perspective as fragile and contingent: what seems urgent or meaningful in ordinary life can be instantly eclipsed by mortality and responsibility. In that sense, it functions as a memento mori filtered through modern, conversational candor—an argument for humility and for valuing relationships and well-being over status, work anxieties, or public noise.
