What's the difference between active surveillance and observation for low-risk p...

I have very low-risk prostate cancer and my oncologist mentioned two monitoring approaches: active surveillance and observation. From what I understand, active surveillance involves more frequent check-ups with PSA tests, exams, and periodic biopsies to closely track any changes. Observation uses less intensive monitoring with visits up to once a year and focuses more on symptom management. I'd love to hear from others who have been in a similar situation and what your experience has been like with either approach. • If you chose active surveillance or observation, what has your monitoring schedule been like? • What factors helped you decide between the two approaches?
