Senescence is the biological process of , characterized by a gradual decline in the functional capabilities of cells and whole organisms. It acts as a double-edged sword: while it prevents the growth of damaged or cancerous cells, the long-term accumulation of these "zombie cells" drives chronic inflammation and age-related diseases. The Two Levels of Senescence
Senescent cells are identified by specific physical and chemical changes: Senescence
