Early detection of intestinal (colorectal) cancer dramatically improves outcomes. Screening reduces both incidence and mortality—yet far too many people still aren't getting tested. Our goal is simple: get more people screened, earlier.
All funds from this event support BOND — the Bulgarian Oncological Scientific Society, a non-profit successor to Bulgaria's national oncology society, advancing cancer science, education, and care.
Bulgaria historically has no nationwide, population-based CRC screening program—but momentum is building. A national campaign in 2024 tested more than 93,000 people using free FIT kits. Your participation helps keep screening in the spotlight.
The best test is the one you get done—talk to your doctor about the right option for you.
Most national programs invite adults (often 50–74) to do a FIT/FOBT stool test at regular intervals; colonoscopy only if positive.
If you have inflammatory bowel disease, certain hereditary syndromes, or a strong family history, talk to your clinician about earlier and more frequent colonoscopies (often every 1–3 years after baseline).

Yes—many campaigns use "bowel," "colorectal," or "intestinal" cancer to refer to cancers of the colon and rectum.
Average-risk adults typically start at 45–50 (country-dependent). If you have symptoms or risk factors, speak with your clinician about earlier testing.
Yes. Widespread screening reduces cases and deaths by finding precancerous polyps and early-stage cancers.
There isn't a permanent population-based program yet, but large campaigns have shown strong public interest and impact—another reason this event matters.
