    The "5-year survival rate" means that, when someone has had cancer and has been treated for it and hasn't displayed any more signs of cancer for 5 years, he is considered to be "cured" of cancer.

    You're talking about median survival time. Most oncologists use metrics like these since they're easier for the patient to understand than the full statistical model.

    In general, median survival time is a worthless metric. It removes all the co-variables that matter such as age, changes in lifestyle (a patient that is active and healthy is more likely to survive cancer).

    Now what does "median survival time" actually mean? It means the time it takes for 50% of the patients with a given cancer to die.

    Median survival time gets talked about when discussing treatments, but of course every cancer is different and every patient is different, you can have a treatment that doesn't improve median survival time for a group of patients while still having it improve the survival time by 100 years for another patient.

    So really, with cancer statistics, what we're talking about is complete guesswork. You might as well flip a coin 10 times and claim you'll live how many times it lands on heads.

    That is the statistics lie. If you survive 5 years, the treatment is successful. If you die one day after 5 years of cancer, the treatment still counts as successful. 

    I would not try modern treatments.

    @Frank is actually right. You can still live a long time with cancer depending on the reason and how fast it grows. A modern treatment lowers your lifetime in most cases.

    A 5 year survival rategives the proportion of people alive 5 years after diagnosis. This proportion live more than 5 years.

    In some cases the 5 year survival rate is very low and people are unlikely to survive that long.

    In other cases it is very high and peopke are likely to survive well beyond 5 years.

    The reason 5 years is used as a benchmark is that simply due to age (80% are over 50) many patients develop and other health issues beyond this time that affect survival and skew the results.

    The five year survival rate is a way of evaluating cancers. You take the percentage of diagnosed people who either have no recurrence, are fine, or are dead. It's just a fixed point for statistics.

    Most people live longer. Had my cancer in 2002.

    No.  You've misinterpreted the information.  Data is collected for five years and a percentage is calculated.  The survival rate is simply the percentage of thousands of people with a particular type of cancer who are still alive after 5 years.  Some are in complete remission, some still have cancer, some may be cancer free but get cancer again.  Some are alive for many years or decades. There are different rates for different types and stages of cancer. It is not a prediction of the odds for any one individual but a general trend.

    Shithead...people EXAMINE the "5 year survival rate" as the SUCCESS or FAILURE of their CANCER TREATMENT/ is not whether or not 5 years is the SURVIVAL RATE. You can have cancer as a CHILD and live to 100.
