Also known as:
- TNBC
- ER/PR negative
- HER2 negative breast cancer
What is triple negative breast cancer?
TNBC is a relatively aggressive breast cancer that is not affected by hormones in the same way as more common forms of breast cancer. It is also more common in younger patients and those with African ancestry.
How rare is TNBC?
It occurs in around 13 people per 100,000 but it only makes up around 20% of all breast cancers, so it is considered to be rare.
Who does TNBC affect?
It mainly affects women but can occur in men. It is more common under the age of 40 and in women of African ancestry.
Why is RareCan interested in TNBC?
RareCan is working to accelerate research by making it easier for researchers to connect with people with triple negative breast cancer. You can help us do this by becoming a RareCan member and sharing information with us about your diagnosis. We will then get in touch with you about any research opportunities that might be suitable for you.
