Cologuard positive. Can I have a colonoscopy 8 months after radiation?

Yesterday I found out my Cologuard test result for colorectal cancer was positive. I'm 73 years old, no history of colorectal cancer. Previous Cologuard test three years ago was negative. Gleason 9 diagnosed in August 2024, limited to prostate, finished 28 sessions of IMRT radiation early April 2025, been on Orgovyx since that time. Blood results two weeks ago: PSA less than 0.04, testosterone less than 1, white blood count 2.1 (2,100). Been researching whether it's advisable to have a colonoscopy 8 months or so after IMRT radiation. Will contact my primary care physician, urologist, and radiation oncologist for their advice. I welcome your thoughts, suggestions, recommendations. Thank you.
