My husband has been at Stage 4 since 2011, so for 13 years now. We have met many other men who have been at Stage 4 long enough that they consider their metastatic prostate cancer a chronic disease which cannot be cured but can be controlled. If you are under the treatment and monitoring of experienced providers at a highly rated cancer center, this is possible for you too, Phil. (Hooray for your daughter--you are lucky she is involved.)
