The percentage of people with a certain cancer who still have no evidence of disease (cancer) at a certain period of time (usually 5 years) after treatment.
Five-year relative survival rate is the ratio of a cancer patient’s chances of surviving 5 years compared to that of an average cancer-free person of the same age and sex. It compares the number of people who are still alive 5 years after their cancer was found to the survival of others the same age who don’t have cancer. This helps correct for other causes of death and is a better way than survival rates alone to see the impact that cancer can have on survival.
Five-year survival rate is the percentage of people with a given type or stage of cancer who are alive 5 years or longer after diagnosis. It does not take into account actual causes of death, so some non-survivors might have died from causes other than cancer.
Survival rates cannot predict any one person’s outcome, which can be affected by many factors.
