Survivor since 2012
Although I never look at the statistics, I do know that the survival rate has gone up significantly over the last 5-10 years. There are many forms of treatment that can extend the life of a cancer patient.
Also, the survival rate depends on SO many factors. Age, type (lobular, invasive, etc)., stage, oncotype, hormone receptors (present or absent), and a number of other things.
If you want honest and accurate answers your doctor is the best resource. Some of them may be reluctant to give prognoses. If that's the case and you really want the statistics, my suggestion is that you be persistent. If your doc won't tell you, get another opinion.
Best of luck to you!
