What is triple negative breast cancer (TNBC) Awareness month?

TNBC Awareness Month, also known as triple negative breast cancer month, takes place in March. It focuses on raising awareness and improving understanding of triple negative breast cancer (TNBC), supporting people affected by TNBC, and keeping attention on the need for continued progress in TNBC research, treatment options and outcomes.

TNBC awareness matters because TNBC is a distinct breast cancer subtype and behaves differently from other breast cancer types - which can affect diagnosis, treatment decisions, outcomes and lived experience. That’s why access to reliable, TNBC-specific information and support is essential.

TNBC Awareness Month’s core aims include:

  • Improve public understanding of TNBC: increasing understanding that TNBC is a distinct breast cancer subtype that requires specific information, support and treatment

  • Reduce misinformation and confusion: correcting myths and over-generalised advice that may not apply to TNBC

  • Support people affected by TNBC: helping those diagnosed find TNBC-specific information, signposting to support services and networks, and encouraging compassionate, informed support from friends, family and workplaces

  • Drive progress in research and treatment: Keeping attention on the need for continued TNBC research and raising awareness of clinical trial participation opportunities

  • Encourage action throughout March: Encouraging people to share accurate TNBC information and to take part in fundraising or make a donation for TNBC-focused charity work

What is TNBC Day?

TNBC Day is marked on 3 March each year and acts as a focal point within TNBC Awareness Month (March).

It’s a day when people share reliable TNBC information, amplify lived experience, and raise support for TNBC-specific education, support and research.

How can I take part in TNBC Awareness Month?

Even small actions during TNBC Awareness Month in March can help more people recognise TNBC, find reliable information, and feel supported. Here are practical ways to take part:

  • Share reliable TNBC information

    Share trustworthy TNBC information and resources from The UK Charity for TNBC and other credible organisations so people can find accurate TNBC-specific information quickly.

  • Share your TNBC story

    If TNBC has affected you, sharing your experience can help others. By sharing what diagnosis, treatment or support was like for you, you may help someone else with TNBC pick up useful tips, reassurance, or questions to raise with their clinical team.

  • Be there for someone affected by TNBC

    Practical support often matters more than the “perfect words”. Check in, listen, and offer specific help - for example, lifts to appointments, meals, childcare, or company during treatment.

  • Use social media to amplify the voice of TNBC

    Follow and share posts from The UK Charity for TNBC on Instagram, Facebook and Tiktok, or share your own story using the hashtag #TNBCAwarenessMonth and #TNBCDay.

  • Donate or participate in fundraising events

    Donations and fundraising help sustain TNBC-specific education and support, and help drive progress in TNBC research and treatment, helping to improve outcomes.
