STOMACH CANCER AWARENESS DAY
NOVEMBER 30TH, 2026

The Power of Periwinkle™ is a global, volunteer-led initiative that shines a light on stomach cancer awareness every November. Since 2017, when My Gut Feeling first launched the campaign, landmarks and community spaces around the world have been illuminated in periwinkle blue—the official colour of stomach cancer awareness.

What began with 6 sites across Canada has grown into an international movement, with more than 150 locations now participating across continents. From iconic city skylines and historical landmarks to local community hubs, each glowing site is a beacon of hope, awareness, and solidarity for everyone impacted by stomach cancer.
