What is Metastasis Cancer?
Metastasis is the medical term for cancer that spreads to a different part of the body from where it started. When this happens, doctors say cancer has “metastasized.” Other names for metastasis are “metastatic cancer” and “stage 4 cancer.” Sometimes the term “advanced cancer” also describes the metastatic disease, but this isn’t always true. For instance, “locally advanced” cancer is not the same as metastatic cancer. It describes cancer that has spread to nearby tissues or lymph nodes but not throughout the body. Metastases (the plural form of metastasis) most commonly develop when cancer cells break away from the main tumor and enter the bloodstream or lymphatic system. These systems carry fluids around the body. This means that the cancer cells can travel far from the original tumor and form new tumors when they settle and grow in a different part of the body. Metastases can also sometimes develop when cancer cells from the main tumor, typically in the abdominal (belly) cavity, break off and directly “seed” other areas within the abdominal cavity.
