TUMOR METASTASE Meaning and
Definition
-
Tumor metastasis refers to the process by which cancerous cells spread from the primary tumor site to other parts of the body, forming secondary tumors or metastases. In this process, cancer cells detach from the primary tumor and invade surrounding tissues. They can then enter the bloodstream or lymphatic system, which serve as conduits for their dissemination to distant organs or tissues.
Metastasis plays a crucial role in cancer progression and is one of the hallmarks of advanced stages of cancer. It greatly contributes to the complexity and lethality of the disease. The ability of cancer cells to metastasize is a result of several sequential steps. First, cancer cells need to acquire the ability to invade through the basement membrane and connective tissues. Then, they must adapt to the circulation, survive in the bloodstream, and eventually extravasate into distant tissues to form new tumors.
Metastatic tumors are generally more difficult to treat than primary tumors because they are often resistant to conventional therapies, such as surgery or radiation. They can also cause significant damage and dysfunction to vital organs or tissues, leading to more severe clinical manifestations and worse prognosis for the patient. The identification of metastases through imaging techniques, such as X-rays, CT scans, or PET scans, is essential for staging and planning appropriate treatment strategies. Targeted therapies and systemic treatments, such as chemotherapy, immunotherapy, or targeted molecular agents, are commonly employed to manage metastatic tumors.

Etymology of TUMOR METASTASE
The word "tumor metastasis" consists of two main components:
1. Tumor: The word "tumor" comes from the Latin word "tumor", which means "swelling" or "bulge". It originated from the Latin verb "tumere", which means "to swell". Over time, the term "tumor" became specifically associated with an abnormal mass or swelling in the body, often associated with cancer.
2. Metastasis: The word "metastasis" is derived from the Greek word "metastasis" (μετάστασις), which also means "movement" or "change". In medical terms, "metastasis" refers to the spread of cancer cells from the primary site (original tumor) to another location in the body, forming secondary tumors.
