Yes, the absolute number of deaths is significant. There is a debate within the medical community over whether the slower growing type should be relabeled as not-cancer / pre-cancer, etc., as surveillance is the more typical treatment plan these days. This in turn will increase the death rate percentage of the remaining (fast growing) cases.

Also worth mentioning that it's not just about surviving it, there's also quality of life. The earlier you catch it the better the outcome.

If it doesn't escape the prostate, a tumor could potentially impinge on the urethra causing urinary difficulty. There is a benign version of this called BPH and it may be treatable by medications like Flowmax.

But it's not like we can always know it will stay slow growing forever. Some cancers can suddenly become aggressive and metastasize, so careful monitoring is important.
