Several key processes underline many diseases, including: - Inflammation: The body's response to injury or infection, which can become chronic if unresolved. - Cell Death: Either through necrosis (unplanned cell death due to injury) or apoptosis (programmed cell death). - Immune Response: The body's defense mechanism that can sometimes lead to autoimmune disorders. - Neoplasia: Uncontrolled cell growth leading to tumors, which can be benign or malignant (cancerous).
