The Leukemia That Kept Vanishing With Every Infection
An 80-year-old woman with untreated acute myeloid leukemia watched her cancer retreat from her blood three separate times, each in step with a different serious infection — a mycobacterium, an aspergillus fungus, and an E. coli bloodstream infection. She received no chemotherapy, yet survived more than two years past the expected end-stage horizon. Her doctors published it as a documented case of repeated spontaneous remission, and pointed to the immune system, jolted awake by infection, as the likely engine. It is one of the rarest patterns in all of oncology — and the mechanism is real but only half-understood.

Establishes rarity: <100 adult cases ever; 46 by modern criteria; ~91% associated with febrile infection; median remission ~5 months. Corroborates both the rarity and the leading natural mechanism.
