It’s estimated that there are 35,000 people in the UK living with secondary breast cancer.

Most people diagnosed with breast cancer will not get secondaries, but some do:

  • Roughly five in every 100 people with breast cancer already have secondaries when their cancer is first diagnosed
  • It is roughly estimated that a further 35 out of every 100 people with primary breast cancer will develop secondary breast cancer within 10 years of their first breast cancer diagnosis

Some people with primary breast cancer are less likely to develop secondary breast cancer than others.

If you have primary breast cancer and would like to know more about your chance of developing secondary breast cancer, ask your treatment team.
