Why is it always stage 4 terminal cancer?

This meme jokes about the common experience of searching minor health symptoms on Google leading to extremely exaggerated, worst-case medical diagnoses, answering the titular question. The top text first presents two mild assessments of an illness: a mother says 'It's just a cold' and a doctor agrees 'Yeah it's just a cold'. The entry labeled 'Google:' is followed by the fully progressed symptom and global spread UI from the video game Plague Inc, showing total organ system failure and worldwide infection, implying that Google will diagnose a minor common cold as a catastrophic, life-threatening pandemic-level illness, aligning with the widespread experience of Google symptom searches leading users to believe they have severe, terminal conditions even for minor ailments.

This meme is sourced from the Reddit:Meme RSS feed. It remixes UI assets pulled from the popular strategy game Plague Inc, where players evolve a pathogen to infect the global population and cause mass harm. It taps into a widely shared internet trope mocking the alarmist results of searching health symptoms on Google, which often overrepresent rare severe conditions over common minor illnesses. It is a user-created edited meme combining original text jokes with pre-existing game assets.
