metastaattisiin

Metastaattisiin is the Finnish term for metastatic. It refers to the process by which cancer cells spread from their original location, the primary tumor, to other parts of the body. This spread can occur through the bloodstream, the lymphatic system, or by direct extension into surrounding tissues. When cancer becomes metastatic, it is considered more advanced and often more difficult to treat. The new tumors that form in distant sites are called secondary tumors or metastases. These metastatic tumors are composed of the same type of cells as the primary tumor, indicating that the cancer has spread. Common sites for metastasis include the lungs, liver, bones, and brain, although this can vary depending on the type of primary cancer. The development of metastases is a significant factor in cancer mortality and morbidity. Research into understanding and preventing metastasis is a major focus in cancer research. Treatment for metastatic cancer often involves systemic therapies that can reach cancer cells throughout the body, such as chemotherapy, targeted therapy, or immunotherapy, in addition to local treatments for specific metastatic sites.
