Cancer (medicine)

Cancer, tumor, cancer syn. Malignancy is the medical term a malignant (malignant) tumor - a malignant tissue growth (neoplasia). In a narrower sense, the malignant epithelial tumors (carcinomas) and malignant mesenchymal tumors (sarcomas) are meant. Colloquially also haemoblastoses the malignant than cancer such as leukemia, as "blood cancer" refers to.
All other tumors, which include benign (benign) neoplasms, are not a "benign cancer" or some form of cancer. These are tissue proliferation or masses in the body that do not form metastases. This applies to both the swelling in inflammation and benign neoplasms (new growths of body tissue by Dysregulation of cell growth).
Benign tumors including moles and fatty tumors (lipomas) are not in the technical language called cancer, but they can still be dangerous, as they may degenerate or be detrimental to vital organs in their functioning (such as the cerebellum-bridge angle tumor). Cancer is a generic term in common language for a variety of related diseases in which cells grow uncontrollably, share and destroy healthy tissue and can displace. Cancer has different triggers, which ultimately result in a disruption of all genetically controlled balance between cell cycle (growth and division) and death (apoptosis).
Devoting themselves to the cancer medical discipline is oncology.
