Stage 4 breast cancer refers to cancer that has spread beyond the breast tissue into other areas of the body. To understand the prognosis for stage 4 breast cancer, it helps to know something about the process of metastasis. In the case of breast cancer, receiving a stage 4 diagnosis may mean the cancer has reached organs outside of the breasts, such as your bones, lungs, liver, or even your brain.
Breast cancer metastasis accounts for the majority of deaths from breast cancer. Detection of breast cancer metastasis at the earliest stage is important for the management and prediction of breast cancer progression. Emerging techniques using the analysis of circulating tumor cells show promising results in predicting and identifying the early stages of breast cancer metastasis in patients.
In metastasis, cancer cells break away from where they first formed primary cancertravel through the blood or lymph system, and form new tumors metastatic tumors in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor. Cancer cells can spread locally by moving into nearby normal tissue.

Metastatic breast cancer is also classified as Stage 4 breast cancer. The cancer has spread to other parts of the body. This usually includes the lungs, liver, bones or brain.
Common sites include distant organs like the lung, liver, bone and brain. Even after an original tumor is removed, microscopic tumor cells may remain in the body, which allows the cancer to return and spread. Patients may initially be diagnosed with metastatic diseaseor they may develop metastases months or years after their initial treatment.
Metastatic breast cancer is breast cancer that has spread beyond the breast to other organs in the body, most often the bones, lungs, liver or, less commonly, brain. There are many words used, but they actually mean the same thing. When referring to a specific area or site of metastatic breast cancer, the term secondary is often used — for example a secondary in the bone.
Metastatic breast canceralso referred to as metastasesadvanced breast cancer, secondary tumours, secondaries or stage 4 breast cancer, is a stage of breast cancer where the disease has spread to distant sites beyond the axillary lymph nodes. There is no cure for metastatic breast cancer. There is no stage after IV.
Metastatic breast cancer also called stage IV is breast cancer that has spread to another part of the body, most commonly the liver, brain, bones, or lungs. Cancer cells can break away from the original tumor in the breast and travel to other parts of the body through the bloodstream or the lymphatic system, which is a large network of nodes and vessels that works to remove bacteria, viruses, and cellular waste products. Breast cancer can come back in another part of the body months or years after the original diagnosis and treatment.
