Patients rely on health-care professionals to provide them with relevant and clear information about their disease and its treatment. Recent research has shown that physicians are viewed as the most important source of information for patients with breast cancer; however, physicians do not necessarily provide patients with the information they need to be able to make an informed decision, as discussed in this Viewpoint.
Breast cancer screening requires a high level of compliance in order to be effective. The author of this Viewpoint discusses the socio-economic and cultural factors associated with screening in developing countries.
Tubercular lymphadenitis of the cervical lymph nodes can be easily confused with node metastases. Chaturvedi et al. present the case of a 66-year-old man who was diagnosed with tongue carcinoma. PET–CT imaging suggested extensive neck-node metastases but frozen sections revealed tuberculosis of the neck nodes. The patient underwent surgery and received multidrug antitubercular therapy. The need for cautious interpretation of PET–CT reports, especially in tuberculosis-endemic areas, is discussed.
