The Board granted service connection for chronic lymphocytic leukemia (CLL) based on the Veteran's participation in toxic exposure risk activities during service.
The deciding factor: The July 2025 private medical opinion, which found that the Veteran's CLL was at least as likely as not caused by her exposure to ethylene oxide gas and other cleaning chemicals during service, held considerable weight in favor of the claim.
