NEW YORK, NY — As the world enters the second week of Breast Cancer Awareness Month, a global movement is preparing to shift the spotlight from general awareness to the stark reality of the disease’s most lethal form. On October 13, 2026, designated as National Metastatic Breast Cancer (MBC) Awareness Day, more than 325 landmarks across the globe will be illuminated in the symbolic colors of teal, green, and pink. This coordinated display, known as the #LightUpMBC campaign, aims to honor those lost to the disease, support the hundreds of thousands living with it, and raise vital funds for research that remains the only hope for a cure.
The campaign, organized by METAvivor Research and Support, represents a critical intervention in the traditional "pink" narrative of October. While early detection and survivorship are frequently celebrated, the #LightUpMBC initiative highlights the often-overlooked community of patients for whom there is no "finishing treatment."
Main Facts: A Global Beacon for Stage 4 Research
The 2026 #LightUpMBC campaign is set to be the largest in the organization’s history. Spanning all 50 U.S. states and reaching into 20 countries and 195 cities, the initiative uses architectural lighting to transform public spaces into platforms for advocacy. Participating landmarks include iconic structures such as One World Trade Center in New York City, the Willis Tower in Chicago, Philadelphia City Hall, and the Memorial Bridge in Portsmouth, New Hampshire—the site where the movement first began in 2017.
Internationally, the campaign has gained significant momentum. This year, the Ness Bridge in Inverness, Scotland, the Mactan-Cebu International Airport in the Philippines, and Niagara Falls on the Canada-U.S. border will join the roster. These landmarks will glow in a specific tri-color palette: teal represents healing and spirituality, green symbolizes the hope of renewal and life, and pink signifies that the cancer originated in the breast.
The centerpiece of the day’s activities is "#LightUpMBC Live," a virtual broadcast scheduled for 8 p.m. ET / 5 p.m. PT. Hosted by MBC advocate Tami Eagle Bowling and Broadway performer Kara Lindsay, the program will feature a blend of patient testimonials, scientific updates from leading oncologists, and performances by world-class artists. Crucially, 100% of the net proceeds from the campaign and the livestream are directed toward METAvivor’s research grants, which exclusively fund Stage 4 metastatic breast cancer studies.
Chronology: From a Single Bridge to a Global Phenomenon
The origins of #LightUpMBC are rooted in a personal story of friendship and loss. The campaign was founded by Laura Inahara in memory of her best friend, Jessica Moore. Moore was diagnosed with metastatic breast cancer at the age of 32 and passed away just four years later in 2017.
In her final months, Moore expressed a wish to see a local landmark lit up in the MBC awareness colors to help people understand that "awareness" without research funding was not enough for those in her position. In 2017, Inahara successfully petitioned the Memorial Bridge in Portsmouth, New Hampshire, to light up for the cause. What began as a singular, localized tribute quickly resonated with the MBC community, which had long felt marginalized by the mainstream "pink ribbon" movement.
By 2019, the initiative had expanded to dozens of landmarks across the United States. Recognizing the need for a unified voice, the campaign partnered with METAvivor, a non-profit established in 2009 by patients who were frustrated that only a small fraction of breast cancer research funding was directed toward the metastatic stage.
The COVID-19 pandemic in 2020 served as a catalyst for the campaign’s digital evolution. With public gatherings restricted, the organizers launched "#LightUpMBC Live," a virtual event that allowed patients and supporters from around the world to connect. This transition transformed the campaign from a series of physical lightings into a global media event. To date, the initiative has raised over $2.7 million for MBC research, funding multiple grants that explore everything from immunotherapy to targeted molecular treatments.
Supporting Data: The Biological and Statistical Reality of MBC
To understand the urgency of #LightUpMBC, one must look at the clinical reality of the disease. Metastatic Breast Cancer, also known as Stage 4, occurs when cancer cells break away from the primary tumor in the breast and travel through the lymphatic system or bloodstream to settle in distant organs. The most common sites of metastasis are the bones, liver, lungs, and brain.
The Mortality Gap
According to data from the National Cancer Institute’s SEER program, an estimated 42,670 people in the United States are expected to die from breast cancer in 2026. This equates to approximately 117 deaths every single day. Virtually all of these deaths are the result of metastatic disease. Despite these staggering numbers, historical data suggests that only about 2% to 5% of overall breast cancer research funding is dedicated specifically to the metastatic stage.
Diagnosis and Treatment
The path to an MBC diagnosis varies. Some patients are "de novo," meaning they are diagnosed at Stage 4 from the very beginning. For others, the cancer returns as metastatic disease months, years, or even decades after they were told they were "cancer-free" or "cured" following treatment for early-stage (Stage 1-3) disease.
For those living with MBC, treatment is a lifelong commitment. There is currently no cure, and the goal of therapy is to manage the disease as a chronic condition. However, cancer is a moving target; it often develops resistance to specific drugs, forcing patients to cycle through different lines of treatment—chemotherapy, hormonal therapy, and targeted biologics—until they run out of options.
The Role of METAvivor
METAvivor fills a unique niche in the philanthropic landscape. Unlike many larger organizations that focus on prevention or early detection, METAvivor is the only U.S. organization that exclusively funds Stage 4 research. Their selection process is unique as well: research projects are reviewed by a panel that includes both scientific peers and patient advocates, ensuring that the funded research is both scientifically rigorous and patient-centric.
Official Responses: Voices from the Front Lines
The leadership of METAvivor and the creators of #LightUpMBC emphasize that the campaign is about more than just aesthetics; it is about survival.
Dr. Kelly Shanahan, the Board President of METAvivor and a former OB-GYN who has been living with MBC since 2013, highlights the transformative power of research. “When I was diagnosed with metastatic breast cancer in 2013, I certainly didn’t think I’d still be here 13 years later,” Dr. Shanahan said. “My hope and the hope of so many others lies in research, and METAvivor-funded research is increasingly important these days. #LightUpMBC is the biggest contributor to this research, and is also a way to bring us together as a community.”
Laura Inahara, the campaign’s founder, sees the 2026 event as the fulfillment of a legacy. “Jessica hoped to illuminate one local landmark. Today, her legacy helps families around the world shine a light for the people they love, teach patients with MBC how to advocate for themselves and has now raised over $2.7 million for critical MBC research,” Inahara stated.
Tami Eagle Bowling, the campaign director and a host of the live broadcast, has lived with MBC for 11 years. For her, the "Live" event is a way to bridge the gap between the clinical and the personal. The 2026 broadcast will feature performances from high-profile supporters, including two-time Tony Award winner Victoria Clark and Tony Award nominee Dorian Harewood, illustrating the broad cultural support for the cause.
Implications: Changing the Future of Breast Cancer
The #LightUpMBC campaign has profound implications for how society views and treats breast cancer. By forcing a confrontation with the terminal reality of the disease, the campaign challenges the "pinkwashing" often associated with October.
Shifting the Narrative
For decades, the focus of Breast Cancer Awareness Month has been on "the cure" as a destination reached through early detection. However, for the MBC community, this narrative can be isolating and inaccurate, as it implies that those with Stage 4 disease somehow failed to detect their cancer early enough. #LightUpMBC reclaims the month for those who will never be "done" with treatment, fostering a more inclusive and honest dialogue about the disease’s impact.
From Terminal to Chronic
The ultimate goal of the research funded by this campaign is to transform MBC from a terminal diagnosis into a manageable, chronic condition. With the advent of genomic sequencing and personalized medicine, researchers are finding ways to extend the lives of MBC patients significantly. Initiatives like #LightUpMBC provide the financial engine necessary to drive these breakthroughs.
A Call to Global Action
As October 13 approaches, the public is encouraged to do more than just watch the lights. The campaign organizers are urging people to take photos of illuminated landmarks and share them on social media using the hashtags #LightUpMBC and #METAvivor. This digital "wave" of teal, green, and pink serves to educate the public on the difference between early-stage and metastatic disease.
The 2026 #LightUpMBC campaign stands as a testament to the power of patient-led advocacy. What began as a single bridge in New Hampshire has become a global lighthouse of hope, signaling to the 42,670 people who will die this year—and the hundreds of thousands living in the shadow of that statistic—that they have not been forgotten. As the world’s most famous skylines change color on October 13, the message is clear: awareness is the start, but research is the finish line.
