It seems like a high-prevalence low-impact disease. Considering how much he self-scans it’s no surprise he found one of these. The cancers that he could get as a result are not particularly dangerous and lifespan is barely affected by it.

Seems interesting but not consequential.

Hilariously, his self-scans did not catch this.

It's also not cancer. AIG makes him more susceptible to certain cancers, but he does not have cancer yet.

And looking at what he's done compared to the symptoms, it's possible he's been inadvertently self-medicating his condition for a bit.

He's currently blaming his lifestyle before his "biohacking" for his condition.
