What are the odds of surviving breast cancer?
The overall 5-year relative survival rate for breast cancer is 90%. This means 90 out of 100 women are alive 5 years after they’ve been diagnosed with breast cancer. The 10-year breast cancer relative survival rate is 84% (84 out of 100 women are alive after 10 years).
