Metastatic breast cancer is a cancerous tumor that has spread to other parts of the body. Although there is no cure for metastatic breast cancer, specialists can choose some treatment methods to help slow the progression of the disease, while helping patients maintain a better quality of life. Especially with the development of modern medicine, current treatment methods can also prolong the life of patients.

Stage 4 breast cancer is considered late-stage breast cancer because the cancer cells have spread to other organs of the body, such as the bones, brain, liver, and lungs. The treatment of patients with advanced breast cancer is quite difficult and the prognosis depends on the individual patient case.

Stage 4 breast cancer has spread outside the breast and nearby lymph nodes to other parts of the body. When breast cancer metastasizes, it usually affects mainly organs such as the bones, liver and lungs, and sometimes the brain. Treatment for stage 4 breast cancer is mainly aimed at slowing tumor growth and increasing survival.
