Defining the concept of metastasis, it can be said that it is the spread of tumor cells from the place of origin (primary tumor) to other parts and organs of the patient’s body. The main ways of spreading metastases are two: the vessels of the lymphatic system (lymphogenous metastasis) and the blood vessels of the circulatory system (hematogenous metastasis). Thus, metastases are cancer cells that detached from the primary tumor and started their “journey” through the vessels.Discussion of Cancer & Radiology
Carcinoma is a kind of malignant tumors that develop from the epithelial tissue of various organs. According to Kwabi-Addo & Lindstrom (2011), this is a hidden and initial stage of the onset of cancer, when the signs of the disease are not yet visible. In general, the cells of internal organs, skin epithelium and mucous membranes are affected.
Chemotherapy is the treatment of a malignant disease with the help of poisons and toxins that have a harmful effect on malignant tumor cells with a relatively lower negative effect on the host organism. A poison or toxin is called chemo drug, or a chemotherapeutic agent. Drug antitumor therapy (chemotherapy) can be preoperative, postoperative or prophylactic and curative, that is, relating to certain manifestations of the tumor.Discussion of Cancer & Radiology
