Survival rates refer to the percentage of individuals who continue to live after a specific period following a diagnosis or treatment for a disease. These rates are often used in medical research to assess the effectiveness of treatments and to provide patients with information about their prognosis. For example, survival rates for certain types of cancer, such as breast cancer or lung cancer, can vary significantly based on factors like stage at diagnosis and treatment options. Survival rates are typically expressed as one-year, five-year, or ten-year rates, indicating the proportion of patients who survive for that duration after diagnosis. These statistics help healthcare providers and patients make informed decisions about treatment plans and lifestyle changes. It's important to note that survival rates are based on past data and may not predict individual outcomes, as each person's situation is unique.
