General aspects and specific issues of informed consent on breast cancer treatments

Informed consent (IC) is the process by which a patient can make choices about his/her health care; therefore it is considered to be a voluntary authorization given by the patient to the physician. To ensure the patient's right to self-determination, what can the physicians do? When treating breast cancer, there are several specific issues that must be clarified by the IC. We have selected and evaluated the basic elements of IC and mentioned the basic concepts of IC in details. First of all, complete information must be disclosed to the patient (physician's responsibility for medical accountability). The information to be disclosed is summarized in the following three elements: 1) The nature of the treatment/procedure, 2) The relevant risks/benefits, and 3) Reasonable alternatives to the proposed intervention (alternative treatments/procedures). However, the physician is not obliged to persuade the patient to accept the proposed intervention. IC information should be documented in detail on the patient's chart without delay. These issues include IC regarding surgical procedures (mastectomy or breast conservation treatment), IC regarding clinical studies (description of randomized controlled trials), IC regarding genetic diagnosis (ethical issues), and the like. IC means informed decision-making, close relationships between physicians and patients are needed.
