METASTASES Meaning and
Definition
-
Metastases are a plural noun that refers to the spread of cancer cells from their original site to other parts of the body through the bloodstream or lymphatic system. This phenomenon occurs when cancer cells detach from the primary tumor and invade nearby tissues or enter the bloodstream or lymphatic vessels.
When cancer cells metastasize, they can travel to different organs or tissues, where they may form secondary tumors. The ability of cancer cells to metastasize is a significant characteristic that distinguishes them from benign tumors.
Metastases are often the stage of cancer where it becomes more challenging to treat and manage. They can cause damage to the invaded tissues or organs, leading to various symptoms depending on the site of metastasis. Common sites of metastases include the liver, lungs, bones, and brain.
The development of metastases is a critical factor in determining the stage and prognosis of cancer. If cancer cells have spread to other parts of the body, it generally indicates a more advanced stage and may require more aggressive treatment approaches, such as chemotherapy, radiation therapy, or targeted therapies.
Regular monitoring and early detection of metastatic tumors are crucial for managing and treating cancer. Various diagnostic techniques, such as imaging scans, biopsies, and blood tests, are used to identify and locate metastases. Treatment strategies for metastases typically focus on controlling the spread of cancer cells and reducing the size and impact of secondary tumors.
