Cancer, malignant neoplasm: Malignant tumor (right) spreads uncontrollably and invades the surrounding tissues; benign tumor (left) remains self-contained from neighbouring tissue: Specialty: Oncology: Symptoms: Fatigue, lump(s), change in skin, abnormal bleeding, prolonged cough, unexplained weight loss [1] Risk factors
A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is ...
While uncommon in solid tumors, chromosomal translocations are a common cause of these diseases. This commonly leads to a different approach in diagnosis and treatment of hematological malignancies. Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology.
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system. Most common tumors have their ...
Cancers comprise a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] They form a subset of neoplasms. A neoplasm or tumor is a group of cells that have undergone unregulated growth and will often form a mass or lump, but may be distributed diffusely. [28] [29]
A malignant tumor is defined by its capacity to initiate a biological phenomenon known as the metastatic cascade, a complex multi-stage process in which cell invasion precedes further cancer progression and the formation of metastases in distant organs and tissues.
Of the sixteen separate sites the body compared, leukemia was the 12th most common class of neoplastic disease and the 11th most common cause of cancer-related death. [79] Leukemia occurs more commonly in the developed world .
Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis.
