I an 72, diagnosed with metastatic PC last August. My PSA was 62, lymph node, pelvis, and large tumor growing out the back of prostate. I had very mild symptoms such as more frequent urination at night, and some strange leg pains once and a while. My annual physical bloodwork found the very high PSA. After the first exam at the urologist, I asked the same question, what happens if I don’t do anything, he told it would take about a year or so, with worsening symptoms and then….
I went on ADT right after the biopsy, Gleason 9, as of April this year, my PSA is less than 0.1, and symptoms are gone, Plan to go have radiation in about a month, with the possibility of a cure. ADT is no fun, but it is worth it to me. My brother died at 62 from PC, he refused treatment when diagnosed and died 6 months later.
