Based on data from 2015 to 2021, the five-year relative mortality rate is 8.3%.
That means 91.7% of people with female breast cancer are alive five years after diagnosis.
The mortality rate for male breast cancer is higher, at 16%.
What Is Survival Rate?
But it ispresented in many different ways.
In 2019 this number dropped below 20 for the first time.
The usual way to screen for breast cancer is a mammogram.
A mammogram machine takes a picture of the breast tissue using X-rays.
