Cancer Flashcards

1
Q

How do we determine which cancers we screen for and when do we screen for them?

A

-Asymptomatic
-Clinically relevant: high incidence, mortality, morbidity
-Obvious preclinical stage before symptoms present
-Effective treatment for early-stage cancer
=Improved outcome when treated at an early stage
=Shortening disease duration
=Decreasing the severity of the disease
-Must be cheap, safe, simple, minimally invasive, widely available, culturally acceptable
