Colorectal cancer is among several cancers that may travel to other parts of the body—a process called metastasis. In most cases, metastatic colorectal cancer is found in the liver. But it may also spread to the lungs, bones, lymph nodes and central nervous system. Metastatic colorectal cancer presents challenges that may require aggressive surgery, chemotherapy and other treatments. You may also consider talking to your doctor about palliative care to help with symptoms and side effects. Metastatic cancer is different than recurrent cancer, which is cancer that returns to the same part of the body.
