etäpesäkkeelle

etäpesäkkeelle is a Finnish term that translates to "metastasis" in English. It refers to the process by which cancer cells spread from their primary site of origin to other parts of the body. This spreading can occur through the bloodstream, lymphatic system, or by direct extension into surrounding tissues. When cancer cells break away from the primary tumor, they can travel to distant organs or tissues and form new tumors, known as secondary or metastatic tumors.

Metastasis is a critical factor in cancer progression and is often associated with a poorer prognosis. The formation of etäpesäkkeelle signifies that the cancer has become more advanced and aggressive. The location of these secondary tumors can significantly impact a patient's symptoms and treatment options, as they can affect the function of vital organs. Common sites for metastasis include the lungs, liver, bones, and brain, although the specific pattern of spread varies depending on the type of primary cancer. Identifying and treating etäpesäkkeelle is a major focus in oncology, as controlling or eradicating these secondary tumors is crucial for improving patient outcomes.
