Conditional survival

Conditional survival refers to the likelihood of surviving for a certain period given that a person has already survived a specific amount of time after diagnosis or treatment. For example, if a patient has already survived two years, their probability of surviving the next year can be reassessed, often improving the overall outlook. It helps provide more accurate, personalized information over time, reflecting how survival chances change as time passes and health status evolves. This concept is useful for patients and doctors to make informed decisions based on progress rather than initial prognosis alone.
