Numerous well‐known pathways related to tumor development and progression were identified, such as synapse organization (in 26 BD‐cancer patients, 14.4%), cadherin signaling (in 10 BD‐cancer patients, 5.5%), and the Wnt signaling pathway (in 13 BD‐cancer patients, 7.2%). This evidence concerns the gene CDH17 and Behcet disease.
