Patients' Perspective: What has Changed in Deciding about Breast-Conserving Surgery for Early-Stage Breast Cancer in Turkey?

Background: This study aims to describe patients' perception of early breast cancer, factors influencing the choice of operation, patients' sources of information about the disease and the seriousness with which this information is considered, and to address what surgeons can do to enlighten their patients prior to decision-making.

Methods: Patients were asked to complete a questionnaire consisting of 3 sections: The first section addressed influential factors during the decision-making process; the second pertained to the role of surgeons or health facilities in the process; and the third asked patients to revisit their initial choice of surgery.

Results: 237 patients were included in the study.

A study of photomodulated reflectance on staircase-like, n-doped GaAs/AlxGa1-xAs quantum well structures.

In this study, photomodulated reflectance (PR) technique was employed on two different quantum well infrared photodetector (QWIP) structures, which consist of n-doped GaAs quantum wells (QWs) between undoped AlxGa1-xAs barriers with three different x compositions. Therefore, the barrier profile is in the form of a staircase-like barrier. The main difference between the two structures is the doping profile and the doping concentration of the QWs.
