Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.

Nutrients from the food we eat are processed and absorbed by the digestive system. Surgery could be required to remedy or treat certain problems or diseases that affect the digestive tract.
