Q

Describe secondary prevention

A

We don’t know the cause of all diseases so primary prevention cannot always be provided.

Secondary prevention involves screening for early stage disease. We can then provide treatment for those with the early stage of the disease to cure or prevent/delay progression of the disease present and improve prognosis.
