Cancer is the abnormal and uncontrolled growth of cells that forms a tumor. In cases when cells from affected localized site spread to other distant organs we speak about metastasis. One may come across the following names for this phenomenon: metastatic cancer and cancer metastases. It should be mentioned that only malignant tumors spread to other tissues or organs and may be life-dangerous. Such cancer cells spreading affects other organs and causes metastatic tumors. The further metastasis description provides you with information on this topic.

In cases of cancer and metastasis, sometimes cancerous cells, having invaded the blood system or the lymphatic system, spread to other tissues and organs originally unaffected by cancer. Speaking about primary cancer and metastasis we can say that the latter is the consequence of the former. Once in the blood vessels cells spread to other tissues and cause tumors there. Such tumors are called secondary tumors since they contain cancerous cells from other organ or tissue.
