How Chemotherapy Kills Cancer Cells 🔬 How to Save Yourself From Choking 😨

Chemotherapy works by targeting one of the defining features of cancer: rapid and unchecked cell division. Unlike healthy cells, which grow, divide, and die in a tightly regulated cycle, cancer cells mutate and multiply relentlessly. Chemotherapy drugs are systemic treatments—meaning they travel throughout the entire bloodstream—designed to interrupt this cycle and destroy malignant cells at specific stages of their growth. Choking is a life-threatening emergency that occurs when an object—usually food—blocks the trachea, cutting off oxygen to the lungs and brain. While we often rely on others to perform the Heimlich maneuver, knowing how to perform self-resuscitation can save your life if you are alone.
