What I Learned Using AI When My Brother Got Sick

A software developer used AI to interpret his brother's medical records, blood work and scan reports after doctors diagnosed stage 4 lung cancer that had spread to the brain, asking how likely each possibility was rather than for a diagnosis. AI repeatedly surfaced sarcoidosis, a condition that runs in his family and can mimic cancer on PET scans. Multiple biopsies later confirmed neurosarcoidosis, and the brain lesions shrank by about 75 percent after treatment.
