The article describes ethical and law dilemmas that physicians encounter nowadays. After a short deontological and law review the author points out and descibes from the medical and deontological point of view three representative examples taken out from nowadays soci­ety (hunger strike, surgical split of conjoined twins and patients with anorexia nervosa) whe­re there is an evident disharmony between physician’s perception of patients’ best interests and the patients’ wishes. The physician must always act in patients’ best interests, observing patients’ dignity and their right to make decisions regarding their health issues. The right of making decisions regarding life and death loads physicians with harder duties and respon­sibilities, that exceed treatemet and force physicians to decide in/of ethical and moral dis­putable circumstances.
