Disease progression refers to the process by which a disease develops and worsens over time. It can involve various stages, starting from initial symptoms to more severe manifestations. Understanding this progression helps healthcare professionals predict outcomes and tailor treatments for conditions like cancer, diabetes, or Alzheimer's disease. Factors influencing disease progression include the type of disease, individual health, and environmental influences. For instance, lifestyle choices such as diet and exercise can impact the speed at which a disease advances. Monitoring these factors is crucial for effective management and improving patient quality of life.
