'No Woman Left Behind': World Ovarian Cancer Day 2025 Theme & Significance

Every year on May 8, the world observes World Ovarian Cancer Day to spread awareness about ovarian cancer, the second most common type of gynaecological cancer. This year marks the 13th year of the global campaign, led by the World Ovarian Cancer Coalition, which partners with nearly 200 advocacy groups around the world.

'No Woman Left Behind': World Ovarian Cancer Day 2025 Theme & Significance

For 2025, the theme is “No Woman Left Behind”, focusing on the need for better awareness and early detection so that outcomes for women can improve. To support the cause, the coalition is asking people to join the conversation on social media using the hashtag #WOCD2025. They’ve also released a “Get Involved” guide to help communities raise their voice and educate others.

One of the greatest challenges with ovarian cancer is that many people are not aware of it until it's too late. In fact, a recent survey by the coalition across 22 low- and middle-income countries found that nearly 75% of women diagnosed with ovarian cancer had never even heard of the disease before their diagnosis. Because of this lack of awareness, the illness often goes undetected until it reaches an advanced stage, making treatment more difficult and the outcomes less positive.

Unlike breast or cervical cancer, there is no routine screening test for ovarian cancer. Doctors typically rely on ultrasounds and CA-125 blood tests only when they suspect ovarian cancer.

Another reason for late diagnosis is that the early signs are often vague or ignored. Here are some common symptoms:

- Constant bloating or feeling full

- Pain or discomfort in the lower abdomen

- Needing to pee more often

- Changes in appetite

- Irregular periods

Because these symptoms can seem minor or similar to other health issues, many women delay seeing a doctor until the problem worsens. Health experts stress the importance of paying attention to these warning signs. Ovarian cancer can be silent, but it is not invisible. With more awareness, women can recognise the early signs and seek help sooner.

This World Ovarian Cancer Day, the message is clear: no woman should face this disease without information or support. Better education, early detection, and equal access to care can help save lives.
