Metastatic Breast Cancer Symptoms
When the cancer has advanced fully, it spreads out to other organs. The process of spreading out from the original site is called metastasis, and the stage is referred to as metastatic breast cancer. Sometimes, all cancer cells do not die even after treatment for cancer, and these cells can break out from the original site and travel to other organs through blood vessels and lymphatic vessels, and develop tumors in other organs. This recurrence of cancer in other organs is called metastatic breast cancer, too.
