This document discusses two dilemmas in David's situation: whether he is mentally competent to make his own medical decisions, and whether information should be withheld from him at his wife's request. It notes that David's mental state at various points is unclear. The physician should have an in-depth discussion with David's wife about her reasons for wanting to withhold a cancer diagnosis from David, given his stated suicide threat. Ultimately, the physician canceled the biopsy, so there will be no results to disclose or withhold.
