Metastasectomy is a surgical procedure used to remove metastatic cancer cells that have spread from the primary tumor to other parts of the body. Some synonyms for the term metastasectomy include metastatic tumor resection, excision of metastases, removal of secondary tumors, and metastasis removal. These terms are commonly used in medical literature to describe the surgical removal of metastatic cancer from different organs like the liver, lungs, and bones. While metastasectomy can be effective in treating certain types of cancer, it is not always an option for all patients and is usually considered for patients with a limited number of metastases.
