## Problem 255 — rank:41

**Title:** Dormant-cancer-cell reactivation

**Added binding assumptions (LaTeX):**

```latex
Condition relapse forecasts on being alive and relapse-free at the prediction time, and handle death as a competing event rather than silently removing it from follow-up. Specify the dormant-cell number distribution and post-awakening branching/growth law. An awakening hazard cannot be recovered from clinical detection times alone without a constrained detection-delay model. Compare total relapse effects separately from controlled effects on awakening at fixed subsequent growth.
