Dr. Graber’s research is focused on the interactive roles of occupational and behaviors risk factors (such as tobacco use) on cancer incidence. Her current research assesses risk factors and mechanisms for head and neck cancer. She is specifically exploring possible causal pathways wherein exposure to the pollutants from the World Trade Center (WTC) attacks and subsequent rescue and recovery efforts may mediate or moderate associations between well-established risk factors for head and neck cancer incidence, including smoking tobacco, excess alcohol use, and oral infection with the human papilloma virus (HPV). This work has the long term goal of cancer prevention among emergency responders, including firefighters.
