A 74-year-old man comes to the clinic accompanied by his son to discuss recent prostate biopsy results, which confirm early-stage prostate adenocarcinoma. The physician outlines the available treatment options, including radical prostatectomy, radiation therapy, and active surveillance. The patient has a medical history of hypertension and mild Alzheimer dementia, which was diagnosed two years ago. During the discussion, the patient is fully oriented to person, place, and time. He accurately summarizes his diagnosis, the proposed treatment options, and the potential consequences of refusing standard medical care. He then states, "I understand that without conventional treatment, the cancer might spread and shorten my life. However, my brother suffered terrible complications from a similar surgery, and I refuse to undergo any medical procedures. I will rely exclusively on dietary changes." Later that day, the patient's son, who is the legally designated healthcare proxy, contacts the physician privately. The son insists that his father's dementia makes him incapable of making sound decisions and demands that the physician schedule the surgery. Which of the following is the most appropriate next step in management?
