Through analyzing the significance of three choices facing medical students,namely, postgraduate examination,employment and clinical training,the author pointed out that the inner contra-dictions of the three lie in time conflicts,incomplete national policy and the trade-off among medical col-leges,teaching hospitals and medical students. To resolve the conflicting issues above,the author advised students to adjust the time,strengthen management and ideological educations,improve teaching meth-ods and increase the weight of clinical knowledge in the postgraduate examination and employment.

Breast cancer and lung cancer are the two most common malignancies in China. With the continuous improvement of breast cancer diagnosis and treatment technology, the survival time of breast cancer patients has been prolonged, and the number of breast cancer patients with second primary lung cancer (SPLC) has increased. In addition, breast cancer is the most common primary cancer in female patients with SPLC, and SPLC is the main cause of death in this population. More and more physicians pay attention to this clinical phenomenon. This paper summarized the risk and risk factors of SPLC in breast cancer patients, and elaborated its pathogenesis, in order to provide a theoretical basis for the clinical management of breast cancer patients and achieve accurate early intervention as soon as possible.
