ROBIN SMITH vs. CITY OF SUNNYVALE
This case involves a firefighter claiming breast cancer arose from employment exposure to carcinogens, triggering a statutory presumption of industrial causation under Labor Code section 3212.1. The employer sought to rebut this presumption by arguing a medical examiner found no studies linking applicant's specific exposures to breast cancer. However, the Appeals Board denied reconsideration, affirming that the employer failed to prove there is *no reasonable link* between workplace carcinogen exposure and the applicant's cancer, a higher bar than simply the absence of direct scientific studies. The Board reiterated that an employer must affirmatively demonstrate a lack of reasonable connection, not just highlight a lack of studies supporting causation.
