Is one that is limited to the tissue or organ where it began and has not spread to nearby lymph nodes or other organs. ( stage 1-2 )
What is the general definition of an advanced cancer ?
Is one that is unlikely to be cured or controlled by treatment secondary to features such as : spread to surrounding lymph nodes, tissues or other organs ( stage 3-4 ).

Radical prostatectomy ( life expectancy more than 10 years )
What is active surveillance in the management of prostate cancer ?
The postponement of immediate definitive therapy with the initiation of curative intent treatment if there is clinical evidence of disease progression.

To avoid treatment related complications for men whose cancers are unlikely to progress.
When is watchful waiting an appropriate option for the management of prostate cancer ?
