Metastatic lesions from breast cancer may produce symptoms according to that organ system. The most common sites for metastasis are the bone, lung, liver, and brain. [ 17 ] Skin metastases most commonly extend to the skin overlying the mass, but may spread to the axilla or more distant areas. [ 18 ]
Stage 4 is a metastatic cancer. Metastatic breast cancer has a less favorable prognosis. Receptor status. Cells have receptors on their surface and in their cytoplasm and nucleus. Chemical messengers such as hormones bind to receptors, and this causes changes in the cell.
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.

Several types of cancer are associated with high survival rates, including breast, prostate, testicular and colon cancer. Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. [4] Indeed, pancreatic cancer has one of the worst survival rates of all cancers.
If the tumor is diagnosed early, breast-saving surgery could be an option, although this is relatively uncommon. In non-metastatic MBC, the most common treatment is mastectomy. If the tumor is metastatic, surgery is no longer a viable option, and treatment generally defaults to aggressive chemotherapy.
Triple-negative breast cancer comprises 15–20% of all breast cancer cases [3] and affects more young women or women with a mutation in the BRCA1 gene than other breast cancers. [4] Triple-negative breast cancers comprise a very heterogeneous group of cancers. TNBC is the most challenging breast cancer type to treat. [5]
