NEW YORK, NY — As October marks Breast Cancer Awareness Month, the familiar sea of pink ribbons often dominates the public discourse. However, for the hundreds of thousands of people living with metastatic breast cancer (MBC)—also known as Stage 4—the conversation frequently feels incomplete. While early detection and survivorship stories are vital, the terminal reality of Stage 4 disease remains a shadowed crisis. On October 13, National Metastatic Breast Cancer Awareness Day, the global community will move beyond simple awareness to tangible action through the #LightUpMBC campaign.
More than 325 landmarks across 20 countries, 50 U.S. states, and 195 cities will bathe in the tricolor glow of teal, green, and pink—the official colors of MBC awareness. From the iconic silhouette of New York’s One World Trade Center to the majestic mist of Niagara Falls and the historic Ness Bridge in Scotland, these beacons of light serve as a stark reminder of the lives lost and the urgent need for research funding to ensure those currently fighting the disease have a future.
Understanding the Terminal Reality: What is MBC?
Metastatic breast cancer occurs when cancer cells spread from the primary site in the breast to distant organs, most commonly the bones, lungs, liver, or brain. It is a persistent misconception that once cancer has spread, it is a different disease; however, even when found in the lungs or brain, it remains breast cancer, and the treatment protocols are specific to its origin.
For patients, the diagnosis is life-altering. Some individuals receive a Stage 4 diagnosis at the outset, known as de novo metastatic disease, while others develop the condition months, years, or even decades after completing treatment for early-stage breast cancer.
The treatment path for MBC is an ongoing, lifelong marathon. Unlike early-stage cancer, where the goal is often "clearance," the goal for metastatic patients is to control the disease, extend life, and preserve quality of life. Even when medical scans show "no evidence of disease" (NED), it does not mean the patient is cured. It means the cancer is currently suppressed. Because cancer cells eventually develop resistance to systemic therapies, patients must continually cycle through different, often increasingly toxic, treatment regimens.
The Urgency of Research: By the Numbers
The statistics surrounding metastatic breast cancer are sobering. In the United States alone, an estimated 42,670 people are projected to die from breast cancer in 2026. This translates to roughly 117 deaths every single day.
Despite these figures, only a small fraction of overall breast cancer research funding is dedicated exclusively to metastatic disease. METAvivor Research and Support, the organization behind #LightUpMBC, seeks to correct this imbalance. By exclusively funding Stage 4 research, METAvivor ensures that every dollar raised goes toward projects that aim to transform MBC from a terminal condition into a chronic, manageable, and ultimately survivable disease.
The organization employs a rigorous scientific peer-review process, integrated with patient advocate input, to ensure that the research they fund is not only scientifically sound but also directly addresses the most pressing needs of the patient community.
A Chronology of a Movement: From One Landmark to the World
The genesis of #LightUpMBC is deeply rooted in personal loss and the desire for change. The campaign was founded by Laura Inahara, who was inspired by her late best friend, Jessica Moore.
- 2017: The movement began on a small scale when the Memorial Bridge in Portsmouth, New Hampshire, became the first landmark to illuminate in honor of those living with MBC. Jessica Moore’s dream was modest: she hoped to see her local landmark lit to represent her struggle and that of her peers.
- 2018–2020: Following Moore’s passing at the age of 36, Inahara transformed her grief into a global call to action. The campaign began to expand, garnering interest from cities across the U.S. and eventually internationally.
- 2021–2025: The introduction of #LightUpMBC Live—a digital broadcast—significantly expanded the reach of the campaign. By incorporating storytelling, scientific insights, and musical performances, the movement evolved from a visual display into a global educational event.
- 2026: Today, the campaign stands as a massive, synchronized international event. Having raised over $2.7 million for critical research to date, #LightUpMBC has become the single largest annual contributor to METAvivor’s research grants.
Official Voices: Perspectives from the Frontline
The #LightUpMBC movement is driven by those who understand the reality of the disease most intimately. Dr. Kelly Shanahan, Board President of METAvivor, has been living with a metastatic diagnosis since 2013.
"When I was diagnosed in 2013, I certainly didn’t think I’d still be here 13 years later," Dr. Shanahan remarked. "My hope and the hope of so many others lies in research. METAvivor-funded research is increasingly important these days because it targets the specific mechanisms of metastasis. #LightUpMBC is not just the biggest contributor to this research; it is the heartbeat of our community."
Laura Inahara, reflecting on the growth of the campaign, emphasized the enduring power of the movement: "Jessica hoped to illuminate one local landmark. Today, her legacy helps families around the world shine a light for the people they love. It has become a vehicle for teaching patients how to advocate for themselves and has provided the necessary capital to move the needle on life-extending therapies."
The 2026 #LightUpMBC Live Program: A Night of Solidarity
On October 13, at 8 p.m. ET (5 p.m. PT), the #LightUpMBC Live event will offer a window into the lives of those navigating Stage 4. Hosted by Tami Eagle Bowling—who has lived with MBC for 11 years—and Broadway performer and breast cancer survivor Kara Lindsay, the broadcast is designed to be both educational and deeply moving.
The program will feature:
- Patient Narratives: Live segments filmed from illuminated landmarks, giving voice to the patients and families directly affected by the disease.
- Scientific Briefings: Insights from researchers on the cutting edge of oncology, explaining how new treatments are being developed to combat therapy resistance.
- Artistic Tributes: Performances by luminaries such as two-time Tony Award winner Victoria Clark, Tony Award nominee Dorian Harewood, actress Christina Bianco, songwriter Cassandra Kubinski, and legendary voice artist Tony Daniels.
The event will be streamed for free on the METAvivor YouTube channel and METAvivor Facebook Live, with additional support from LiveOne.
Implications: Moving Toward a Survivable Future
The #LightUpMBC campaign carries profound implications for the future of oncology. By centering the conversation on Stage 4, it forces policymakers, pharmaceutical researchers, and the general public to confront the reality that "awareness" without focused funding leads to stagnation.
The success of the campaign highlights a shift in patient advocacy: the move from passive participation to active partnership. Patients are no longer just recipients of care; they are active, vocal participants in the scientific review process and the primary drivers of fundraising.
As the teal, green, and pink lights wash over cityscapes across the globe, the message remains clear: Metastatic breast cancer is a medical emergency that requires sustained, dedicated investment. With 100% of net proceeds from the campaign going directly to research, the "Light Up" movement is not merely a symbolic gesture—it is a literal investment in the next generation of life-extending medicine.
How to Participate
The public is encouraged to engage with the movement by:
- Visiting a Landmark: Those near participating cities are invited to visit the landmarks, capture photos, and share them on social media using the hashtags #LightUpMBC and #METAvivor.
- Tuning In: Watching #LightUpMBC Live on October 13 to hear firsthand accounts and the latest scientific developments.
- Contributing: Donations can be made directly through the official campaign website at www.lightupmbc.org, where a full map of participating landmarks is also available.
In a world where medical progress is often measured in years, #LightUpMBC serves as a reminder that for those with metastatic breast cancer, every day is a gift—and every light represents a hope for more of them.
