My father was diagnosed with prostate cancer with stage 1 at 79 years old. Then a year later, he was diagnosed with stage 3. Didn't even bother stop at stage 2. Now that he is 81, and within a few months ago his prostate cancer has spread into the lymph nodes and therefor it is now a stage 4.
Within 2-3 years of diagnosed, would you say that he has an aggressive cancer? He told me his psa is less then 1% and a gleason score of 7. He now takes bone scan 2x a year and is on hormone treatment.
Is this a weird case? Or is this a normal findings on my dad's cancer compare to other patients?
