Diagnosed with stage 4 prostate cancer in July. Had 6 infusions of chemo that ended in December. I take casadex and also Lupron shot every three months. PSA went from 138 to 0.45. Had a urnary stent put in last week. Started to experience extreme rectal discomfort a few weeks ago. This is how it all started for me. Worried I went through all this for nothing. Have an oncologist appointment on February 26. I don't know what the next step is.
