disruption of normal cell function due to harmful stimuli
Cell damage, also known as cellular damage or cell injury, refers to the disruption of normal cell structure and function due to various harmful stimuli. This can be caused by factors such as physical trauma, toxins, infections, or oxidative stress. When cells are damaged, they may either repair themselves, undergo programmed cell death (apoptosis), or die through uncontrolled processes (necrosis), potentially leading to tissue dysfunction and disease.
