Why exhibit at AACR
The world's largest cancer research conference -- 23,000 attendees, 600 exhibitors, 141 countries. If you make diagnostic instruments, genomics/sequencing platforms, liquid biopsy tests, or research reagents, AACR is where the global cancer research community sees your technology. The 6-day format gives more time for meaningful booth conversations than typical 3-day shows.
Why exhibit at ACS
The largest general surgery meeting in North America. 80% surgeon audience gives unmatched access to the people who choose instruments, energy devices, and capital equipment for ORs nationwide. High-value face time with department chairs and residency directors.
Why skip AACR
AACR is a research conference, not a clinical buying show. Purchasing authority is low (~20%) because the audience is predominantly academic researchers and scientists, not practicing oncologists with capital budgets. If you need same-quarter device sales, ASCO or ASH is a better fit. The exhibit floor also competes with 730 speaker sessions for attendee attention.
Why skip ACS
If your device is specialty-specific (spine, urology, ENT), you'll be lost among 200 exhibitors targeting general surgeons. Smaller specialty meetings deliver more concentrated buyer access for niche products.
