Metastatic carcinoma
Metastatic Carcinoma
Metastatic carcinoma (pronounced: meh-tuh-STA-tik kar-si-NO-muh) is a type of cancer that has spread from the place where it first started (the primary site) to other parts of the body.
Etymology
The term "metastatic" comes from the Greek metastasis meaning "a removing or a setting over," and "carcinoma" is derived from the Greek karkinos, meaning "crab", and oma, meaning "tumor".
Definition
A metastatic carcinoma is defined as a malignant neoplasm that has spread to sites either adjacent or remote from the primary tumor. This process is facilitated by the ability of cancer cells to detach from the original (primary) tumor and invade surrounding tissue and the circulatory system.
Related Terms
- Primary tumor: The original tumor from which the metastatic carcinomas originate.
- Neoplasm: An abnormal growth of tissue, which can be benign or malignant.
- Malignant: A term for diseases in which abnormal cells divide without control and can invade nearby tissues.
- Cancer: A group of diseases characterized by the uncontrolled growth and spread of abnormal cells.
Diagnosis
Diagnosis of metastatic carcinoma typically involves imaging tests, such as CT scans, MRI, and PET scans, as well as biopsies of the suspected metastatic sites.
Treatment
Treatment for metastatic carcinoma depends on the primary cancer type, the extent of spread (stage), the patient's overall health, and other factors. It may include chemotherapy, radiation therapy, surgery, immunotherapy, or a combination of these.
