etäkasvainten

Etäkasvainten, also known as metastases, are secondary tumors that develop in a location distant from the primary cancer. This process, called metastasis, occurs when cancer cells break away from the original tumor, enter the bloodstream or lymphatic system, and travel to other parts of the body. Once these cells reach a new site, they can begin to grow and form a new tumor. This is a hallmark of advanced cancer and significantly complicates treatment.

The most common sites for metastasis vary depending on the type of primary cancer. For example, breast cancer often metastasizes to the bones, lungs, liver, and brain. Lung cancer can spread to the brain, liver, bones, and adrenal glands. Colon cancer frequently metastasizes to the liver and lungs.

The presence of etäkasvaimet generally indicates a more aggressive form of cancer. Detecting and treating metastases is a crucial aspect of cancer management. Treatment strategies often involve a combination of approaches, including surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapies, aimed at controlling or eradicating the secondary tumors and managing symptoms. The prognosis for patients with metastatic cancer depends on numerous factors, including the type and stage of the primary cancer, the number and location of metastases, and the patient's overall health.
