What does the term "METS" refer to in a medical context?

In a medical context, "METS" typically refers to metastasis, which is the process by which cancer cells spread from the original tumor site to other parts of the body. Metastasis is a critical concept in oncology, as it indicates the progression of cancer and can significantly affect treatment options and patient prognosis.

Understanding metastasis is essential for determining the stage of cancer, evaluating how advanced the disease is, and formulating an appropriate treatment plan. When cancer metastasizes, it can lead to the development of secondary tumors in different organs, which complicates the management of the disease and can alter the overall outlook for the patient. This term is thus crucial for medical professionals in diagnosing, treating, and discussing the implications of cancer with patients and their families.
