Hi Peggy
I can imagine that you are feeling quite bewildered so finding this forum and posting is a great start in continuing to support your Husband however you can.
First of all being diagnosed with diabetes at nearly 76 is not unusual at all many of us succumb to one form of diabetes or another as we get older, at 75 it may just be an intolerance to his own nsulin rather than eating the wrong things, not having enough exercise or carrying too much weight which are all the major contributors to late onset type 2 diabetes which tends to manifest at a younger age.There are qute a few men on this forum who manage to control their diabetes really well alongside any treatment for PCa so take heart from that.
Having any joint replacement that does not go too well is also a difficult and traumatic experience so to be told that hs prostate cancer has started to progress must make it all seem unfair.
Only the specialist can tell you what is happening with his cancer right now, they may need to run a few tests and scans to establish a revised staging and Gleason score. The staging tells you if the cancer is still local and contained or local but starting to push through the prostate wall or surrounding vessels, or if it is advanced and has spread to the lymph nodes, other soft tissue or bones or any combination of these. The Gleason score is derived from analysing samples taken in the biopsy samples are taken from either side of the prostate and the severity/aggressiveness of the cancer is reflected in this figure. So the lowest score these days is usually 3/3 being the least aggressive and the highest is 5/5 being the most aggressive.The combination of these two things along with your Husbands general health and well being and the rate at which his PSA increases will guide the consultants in their recommendations for treatment.
What I would say is with a T1 staging almost 10 years ago and no treatment in that time it sounds as though your husband has one of the very slow developing strains or types of PCa so I really hope that this is the case.
Read the toolkit and soak in as much information from people here but do not get too carried away looking at the internet in general as it can lead you down all the wrong paths and just scare you unnecessarily.
In the 10 years your husband has had this disease enormous steps have been taken to improve the treatments with large numbers of new drugs, types of Radio therapy, chemotherapy and with consultants working as one team across urology, oncology and radiotherapy to come up with the best options.
I hope that is not too much general information in one go, if you think of anything specific or just want some moral support and a virtual hug we are all here for you. You can also talk with the nurses on the number on the home age of this website, they are really understanding and helpful.
Very best wishes
