With breast cancer being the most common tumor among women in the world today, it is also the leading cause of cancer-related deaths. Standard treatments include chemotherapy, surgery, endocrine therapy, and targeted therapy. However, the heterogeneity, drug resistance, and poor prognosis of breast cancer highlight an urgent need for further exploration of its underlying mechanisms.

This study aims to analyze the long-term trend of MBC incidence and develop a competing risk model to improve survival rates. MBC data from the Surveillance, Epidemiology, and End Results (SEER) database (1975-2019) were analyzed using the Age-Period-Cohort (APC) model to examine trends in age, period, and birth cohort effects of MBC incidence.

The present study utilized the "pre- and post-association" experimental paradigm (2010) to test whether the rewarding and aversive properties of MAMPH can be modulated by an N-methyl-D-aspartic acid (NMDA) lesion in the NAc core. Moreover, it tested how an NAc core NMDA lesion affected the innate reward of saccharin solution intake.
