I. Overview:
World Neuroendocrine Cancer Day, also known as NET Cancer Day, is observed annually on November 10 to raise global awareness about neuroendocrine tumors (NETs), a rare and misdiagnosed cancer. It is led by the International Neuroendocrine Cancer Alliance (INCA) and unites patient groups, clinicians, researchers, and advocates around the world to improve diagnosis, treatment, and care.
II. Significance of the Theme
This year attention was on theme “Easily missed: Take a closer look at neuroendocrine cancer” .
III. What are Neuroendocrine Tumors (NETs)?
NETs are cancers originating in neuroendocrine cells, which have traits of both nerve cells and hormone-secreting cells. They can occur in various organs, such as the pancreas, intestines, lungs, and more. NETs often grow slowly and may not cause symptoms until advanced, which complicates early detection.
IV. Quick Facts about NET Cancer
NET Cancer Day is held on November 10 each year.
The zebra is used as the community symbol, the idea that a “zebra” (rare disease) should be considered, not just the common diagnosis.
Around 46% of patients are diagnosed at advanced stages by the time their NET is correctly identified.
NETs are more common than cancers like brain, ovarian, or cervical cancer in some metrics.
Many NET patients spend years with misdiagnoses (sometimes 5–7 years), before the correct diagnosis is made.
V. A Brief History of NET Cancer Day
2010: The first WNCAD was launched on November 10. The inaugural theme was “The Early Detection of NET Cancers.”
2011-20: The observance continued annually under the NET community’s awareness campaigns (often using hashtags like #LetsTalkAboutNETs) and promoted through patient groups.
2021-22: Themes such as “Know the symptoms. Push for diagnosis.” were used to advocate earlier diagnosis.
2023-25: Continues under the theme “Easily Missed: Take a Closer Look at Neuroendocrine Cancer”, reinforcing awareness, earlier diagnosis, and shared responsibility.
VI. How to Observe NET Cancer day?
Use the zebra ribbon or imagery to show support and raise awareness
Share educational content about symptoms, diagnostics, and patient stories
Encourage healthcare providers to keep NETs in differential diagnoses when symptoms persist
Advocate for better funding, research infrastructure, and access to specialized care
Participate in webinars, virtual events, or awareness campaigns under #NETCancerDay, #LetsTalkAboutNETs
Collaborate with NET patient organizations to amplify local and global activities
