STEP 1: Prevention and early detection
Risk factors: As the primary cancer site is not known for people with CUP, it is difficult to identify risk factors. General cancer risk factors include increasing age, male gender, family history, smoking, alcohol, excess body fat, inadequate physical activity, lower socioeconomic status, Aboriginal and Torres Strait Islander people and infrequent GP consultations.
Prevention: The causes of CUP are not fully understood, and there is currently no clear prevention strategy.
