Ovarian Cancer Events and Awareness Days: The Complete List for 2025

Time isn’t on our side when it comes to ovarian cancer. Every year, we lose too many lives to this disease, and that’s exactly why these ovarian cancer events and awareness days and campaigns matter. They’re not just dates on a calendar – they’re opportunities to educate, take action, and save lives.

Let’s cut through the noise and focus on what matters: the key dates and campaigns pushing ovarian cancer research and awareness forward in 2025. Whether you’re a patient, caregiver, or someone who wants to make a difference, here’s your roadmap for getting involved.

Ovarian Cancer Events and Awareness Days 2025:

World Cancer Day

Date: February 4, 2025

Official website: WorldCancerDay.org

Relevant hashtags: #WorldCancerDay, #UnitedByUnique

Established on February 4, 2000, at the World Cancer Summit Against Cancer for the New Millennium in Paris, World Cancer Day has become a powerful platform for change. The day is now led by the Union for International Cancer Control (UICC) to support the goals of the World Cancer Declaration, written in 2008.

The 2025 theme “United by Unique” hits close to home, especially considering our mission at Not These Ovaries. Every ovarian cancer journey is different, but we’re all fighting for the same thing: better treatments, earlier detection, and, ultimately, survival.

This year’s campaign puts people at the center, recognizing that cancer isn’t just a medical diagnosis; it’s a deeply personal battle that affects real lives, real families, and real futures. The United Nations observes this day globally, with hundreds of events targeting misinformation, raising awareness, and reducing stigma.

Time to Talk Day

Date: February 6, 2025

Official website: Rethink Mental Illness and Mind.org.uk

Relevant hashtags: #TimeToTalk

Launched by Mind and Rethink Mental Illness in partnership with Co-op, Time to Talk Day creates space for crucial conversations about mental health. Coming just after World Cancer Day, it provides a perfect opportunity to address the psychological impact of an ovarian cancer diagnosis.

The day emerged from understanding that mental health conversations can change — and save — lives. For those affected by ovarian cancer, whether as patients, survivors, or caregivers, this day reminds us that emotional well-being is just as crucial as physical health in the cancer journey.

Lynch Syndrome Awareness Day 

Date: March 22, 2025

Relevant hashtags: #LynchSyndromeAwareness, #LynchSyndrome

Lynch Syndrome is the world’s most common inherited cancer syndrome, affecting 1 in 370 people, yet most carriers remain unaware of their condition. This genetic mutation dramatically increases cancer risk before age 50, with lifetime cancer risks up to 80%. For ovarian cancer specifically, the risk ranges from 10-12%.

At Not These Ovaries, we recognize Lynch Syndrome’s significant role in ovarian cancer risk. This awareness day reinforces the urgent need for genetic testing and research funding, particularly for hereditary cancer syndromes that affect younger women. Understanding genetic risk factors like Lynch Syndrome can lead to earlier intervention and better survival rates.

Key actions include:

  • Genetic testing if you have a family history of related cancers
  • Regular screenings if diagnosed with Lynch Syndrome
  • Supporting research into prevention and early detection
  • Sharing knowledge about hereditary cancer risk

National Infertility Awareness Week

Date: April 20 to 26, 2025

Official website: InfertilityAwareness.org

Relevant hashtags: #NIAW2025, #InfertilityAwareness

Founded in 1989 by RESOLVE and federally recognized since 2010, National Infertility Awareness Week tackles myths and misinformation about family-building challenges. The movement’s signature orange color represents wellness, compassion, and emotional healing: qualities deeply resonant with the infertility journey.

For the ovarian cancer community, this week holds profound significance. Many patients, especially younger women with LGSOC, face fertility challenges due to cancer treatments. The intersection of cancer care and fertility preservation remains a critical but often overlooked conversation.

At Not These Ovaries, we support research that could lead to fertility-preserving treatments, particularly for younger patients who haven’t completed their family planning journey. This week reminds us that comprehensive cancer care must address survival and quality of life.

The movement aims to enhance public understanding, ensure access to specialists, and educate lawmakers about infertility’s impact. Through shared stories and community support, NIAW breaks down isolation barriers and empowers those facing fertility challenges, whether from medical conditions, cancer treatments, or other factors.

World Ovarian Cancer Day

Date: May 8, 2025

Official website: World Ovarian Cancer Coalition 

Relevant hashtags: #WOCD2025 #WorldOvarianCancerDay #OvarianCancerDay

First launched in 2013 by a global coalition of ovarian cancer advocacy organizations, May 8th has become our most powerful platform for unified action. The initiative began with a clear mission: create a single, powerful voice for ovarian cancer awareness and action worldwide.

Since its inception, World Ovarian Cancer Day has grown from a grassroots movement to a global phenomenon. Organizations, medical professionals, and communities worldwide unite on this day to share critical information about symptoms, push for better research funding, and support those affected by ovarian cancer.

Ovarian Cancer Awareness Month and Gynecological Cancer Awareness Month

Date: September 2025

Official partnerships: Multiple cancer organizations worldwide 

Relevant hashtags: #OvarianCancerMonth #GynCancerMonth

September amplifies our year-round mission to transform ovarian cancer outcomes. This month-long spotlight comes at a crucial time: gynecologic cancers account for 19% of annual cancer cases in women, with ovarian cancer remaining the deadliest among them. The month serves as an extended platform for change, bringing together medical professionals, researchers, advocates, and communities worldwide.

Throughout Ovarian Cancer Awareness Month and Gynecological Cancer Awareness Month in September, healthcare institutions and advocacy groups unite to advance early detection strategies and push for increased research funding. 

The focus extends beyond medical breakthroughs to address the full spectrum of patient needs, from innovative treatment options to comprehensive support programs. It’s a time when policymakers, healthcare providers, and the public come together to tackle both the medical and systemic challenges facing ovarian cancer patients.

At its core, this awareness month drives home an urgent message: we can improve ovarian cancer survival rates through coordinated action, sustained research, and unwavering advocacy. Whether you’re a patient, survivor, caregiver, or supporter, September offers countless ways to join the fight against gynecologic cancers.

Low-Grade Serous Ovarian Cancer Awareness Day (September 9, 2025)

Date: September 9, 2025

Official website: LGSOC Awareness Day

Relevant hashtags: #LGSOCDay, #LGSOCAwarenessDay 

Positioned strategically during Ovarian Cancer Awareness Month, LGSOC Day spotlights a rare but significant subtype that affects younger women: LGSOC, or low-grade serous ovarian cancer. The recent LGSOC Patient Impact Survey revealed a troubling three-year average time to accurate LGSOC diagnosis. That’s three years too many.

LGSOC represents less than 10% of ovarian cancers but presents unique challenges:

  • Typically affects women in their 40s or younger
  • Responds differently to standard treatments
  • Requires specialized research attention
  • Often misdiagnosed due to its rarity

At Not These Ovaries, we’re committing significant resources to LGSOC research because younger women can’t wait years for a diagnosis or settle for treatments that weren’t designed for their cancer type. 

This September 9th, on LGSOC Day, join us in driving real change: share LGSOC symptoms with your network, support dedicated research funding, or connect with others affected by this rare cancer. Every action brings us closer to better detection methods and targeted treatments for LGSOC patients.

World Gynecologic Oncology Day 

Date: September 20, 2025

Official website: WorldGODay.org 

Relevant hashtags: #WorldGODay, #GOAgainstStigma, #NoStigmaInGO, #GOForPrevention, #GynecologicCancer

Founded in 2019 by ENGAGe (European Network of Gynaecological Cancer Advocacy Groups) and ESGO (European Society of Gynaecological Oncology), World GO Day tackles the stigma and silence surrounding gynecologic cancers.

What began as a European initiative has exploded into a global movement, with dozens of organizations hosting hundreds of events worldwide. The day focuses on breaking down barriers to awareness, encouraging early detection, and promoting better understanding of gynecologic cancers.

National Women’s Health and Fitness Day 

Date: September 24, 2025 (Last Wednesday in September)

Relevant hashtags: #WomensHealthFitnessDay

The largest women’s health event of its kind, National Women’s Health & Fitness Day, brings together 80,000 to 100,000 women nationwide. From senior centers to hospitals, parks to health clubs, women of all fitness levels gather to encourage and support each other’s wellness journeys.

For those affected by ovarian cancer, this day takes on special significance. Physical activity and overall wellness are crucial in cancer prevention, treatment, and recovery. At Not These Ovaries, we recognize that a woman’s health journey doesn’t pause with a cancer diagnosis – it becomes even more critical.

Local health facilities nationwide offer free screenings, fitness classes, and health education on this day. It’s an ideal opportunity to raise awareness about ovarian cancer symptoms while promoting overall women’s health. Whether you’re a survivor, patient, or advocate, this day reminds us that physical wellness is vital to the cancer journey.

Hereditary Cancer Awareness Week (September 29 – October 5, 2025)

Date: September 29 to October 5, 2025 

Official partnerships: FORCE

Relevant hashtags: #HereditaryCancerWeek #PrevivorDay #1FORCECommunity

This crucial awareness week emerged from a unanimous Congressional resolution (H. Res. 1522) establishing National Hereditary Breast and Ovarian Cancer Week. A few years ago, FORCE expanded the initiative to include all hereditary cancers, recognizing the broad impact of genetic risk factors.

The statistics are sobering: up to 10% of all diagnosed cancers are linked to inherited genetic mutations, yet 75% of people have never heard of BRCA mutations, and 84% remain unaware of Lynch syndrome. For ovarian cancer specifically, genetic mutations play a significant role: knowledge that could save lives through early detection and preventive measures.

This week honors everyone affected by hereditary cancer risk: survivors, previvors (individuals with genetic predisposition who haven’t developed cancer), those with BRCA1, BRCA2, ATM, BRIP1, CHEK2, PALB2, PTEN, RAD51C, RAD51D mutations, and their families.

The week includes National Previvor Day on October 2, recognizing those who take proactive steps to manage their genetic cancer risk. As Sue Friedman, FORCE Founder and Executive Director, emphasizes: “As many as 90% of the millions of people who have a genetic mutation that causes or predisposes them to cancer are unaware of their risk.”

This awareness week aligns perfectly with our mission at Not These Ovaries to drive urgent action in ovarian cancer research and prevention. Understanding genetic risk factors can lead to earlier interventions and better outcomes, which is crucial for aggressive cancers like ovarian cancer, where early detection saves lives.

World Menopause Day

Date: October 18, 2025 

Official partnerships: International Menopause Society (IMS) and global health organizations 

Relevant hashtags: #WorldMenopauseDay, #MenopauseAwareness, #BreakTheSilence, #HealthyMidlife, #MenopauseSupport, #MenopausePledge

World Menopause Day serves as a crucial platform for addressing a health transition that intersects significantly with ovarian cancer awareness and treatment. Established by the International Menopause Society, this day promotes an understanding of menopause and its health implications for women aged 45-55.

For the ovarian cancer community, this day holds special significance. Many patients experience premature surgery-induced menopause due to cancer treatments, particularly younger women with rare subtypes like LGSOC. 

At Not These Ovaries, we recognize that understanding menopause is crucial for our community, whether it occurs naturally or as a result of life-saving treatments.

The day drives global action through educational programs, awareness campaigns, and community events. Making menopause part of the larger conversation about women’s health helps break down stigma and encourages earlier reporting of symptoms: critical for both menopause and ovarian cancer detection. Through this campaign, you can support women’s health awareness and advocate for better research into how cancer treatments affect menopause experiences.

Getting Involved on Ovarian Cancer Events and Awareness Days

These awareness days and campaigns represent more than dates on a calendar; they’re opportunities to drive real change in ovarian cancer outcomes. Whether you’re sharing symptoms that could lead to earlier detection, supporting research for understudied subtypes, or connecting with others affected by ovarian cancer, every action matters. The science exists to improve survival rates. Now, it’s up to us to fund it, share it, and put it into action.

Choose a campaign that speaks to you, mark your calendar, and join the movement. Together, we can transform ovarian cancer from a silent threat into a treatable, beatable disease.
