👉 Metastases, also known as metastasis, are occurrences of cancer in other parts of the body. These can occur from different locations including organs, lymph nodes, bone marrow, blood vessels, and even the brain. Metastases are often referred to as "cancer cells" because they have spread throughout the body. Metastases can be caused by various factors, such as tumors growing out of other healthy tissue or cells in a patient's body that are not recognized by the immune system
