About hereditary breast cancer

1 in every 14 females in Hong Kong will have breast cancer in their lifetime.1
About 5% to 10% of breast cancers are hereditary.2
If you have a breast cancer gene mutation, your chance of getting breast cancer is 10 times higher than the general population.3

About hereditary ovarian cancer

About 10% to 15% of ovarian cancers are hereditary.2
If you have an ovarian cancer gene mutation, your chance of getting ovarian cancer is 50 times higher than the general population. 3

If you have tested positive for a breast and ovarian cancer gene mutation, it does not mean you definitely will have breast and ovarian cancer. However, your chance of getting breast and ovarian cancer will be higher than the general population.

What can you do if you belong to the high-risk population?

  • Start breast and ovarian cancer screening tests as soon as possible
  • Screen for breast and ovarian cancer more frequently
  • Closely watch out for any breast and ovarian cancer symptoms
  • Learn about options that reduce breast and ovarian cancer risk

Early detection genetic variation and prevention can reduce the risk of breast cancer by 90%, and risk of ovarian cancer by 85%.
