The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
A neoplasm can be benign, potentially malignant, or malignant . [9] Benign tumors include uterine fibroids, osteophytes, and melanocytic nevi (skin moles). They are circumscribed and localized and do not transform into cancer. [8] Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in ...
The ability to invade surrounding tissue and metastasise is a hallmark of cancer.. The hallmarks of cancer were originally six biological capabilities acquired during the multistep development of human tumors and have since been increased to eight capabilities and two enabling capabilities.
There are many general characteristics which apply to either benign or malignant tumors, but sometimes one type may show characteristics of the other. For example, benign tumors are mostly well differentiated and malignant tumors are often undifferentiated. However, undifferentiated benign tumors and differentiated malignant tumors can occur.
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [ 7 ] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority.

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.
In the 15–49-year-old age bracket the most common form of malignancy is breast cancer with liver and lung cancer following. [26] Finally, those aged 60 and over mainly develop lung, colorectal, stomach and liver malignancy.
