CANCER IN KITSAP COUNTY
BACKGROUND
Cancer is complex, can have many possible causes, and is common in the U.S.
1 in 2 males and 1 in 3 females is at risk of developing cancer in their lifetime;
1 in 4 males and 1 in 5 females is at risk of dying from cancer in their lifetime.
Risk factors for cancer include genetic factors, lifestyle factors -- tobacco use, diet,
physical activity -- certain infections, and environmental exposures to different chemicals
and radiation.*
Two important factors to consider:
 the time between exposure or other cause(s) and cancer diagnosis can be quite long;
 access to health care services influences cancer screening frequency, detection, and
treatment.
