Cancer - Classification

Cancers are classified by the type of cell that the tumor resembles and is therefore presumed to be the origin of the tumor. These types include:

  • CARCINOMA Cancer derived from epithelial cells. This group includes many of the most common cancers, including those of the breast, prostate,lung, and colon .
  • STARCOMA Cancer derived from connective tissue or mesenchymal cells.
  • LYMPHOMA and LEUKEMIA : Cancer derived from hematopoietic ( blood -forming) cells
  • GERM CELL TUMOR: Cancer derived from pluripotent cells. In adults these are most often found in the testicle and ovary , but are more common in babies and young children.
  • BLASTOMA: Cancer derived from immature "precursor" or embryonic tissue. These are also commonest in children.

Cancers are usually named using -carcinoma, -sarcoma or -blastoma as a suffix, with the Latin or Greek word for the organ or tissue of origin as the root. For example, a cancer of the liver is called hepatocarcinoma ; a cancer of fat cells is called a liposarcoma . For some common cancers, the English organ name is used. For example, the most common type of BREAST CANCER is called ductal carcinoma of the breast . Here, the adjective ductal refers to the appearance of the cancer under the microscope, which suggests that it has originated in the milk ducts.

BENIGN TUMORS(which are not cancers) are named using -oma as a suffix with the organ name as the root. For example, a benign tumor of smooth muscle cells is called a leiomyoma (the common name of this frequently occurring benign tumor in the uterus is FIBROID). Confusingly, some types of cancer also use the -oma suffix, examples including melanoma and seminoma

Cancer

Cancer (medical term: malignant neoplasm ) is a class of disease which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis , or spreading to other locations in the body via lymph or blood. These three malignant properties of cancers differentiate them from benign tumors, which do not invade or metastasize.

Researchers divide the causes of cancer into two groups: those with a hereditary genetic cause and those an environmental cause. Environmental in this sense means all non-hereditary factors, and encompasses far more than environmental pollusion. About 5-10% of cancers are directly due to hereditary genetic factors. The remaining 90-95% of cases are due to environmental factors, such as old age, lifestyle choices, tobacco use, dietary choices, obesity, infections, radiation, lack of physical activity, and environmental pollutants. These environmental factors cause or enhance non-hereditary abnormalities in the genetic material of cells. Cell reproduction is an extremely complex process that is normally tightly regulated by several classes of genes, including oncogenes and tumer suppressor genes . Hereditary or acquired abnormalities in these regulatory genes can lead to the development of cancer.

The presence of cancer can be suspected on the basis of symptoms, or findings on radiology. Definitive diagnosis of cancer, however, requires the microscopic examination of a biopsy specimen. Most cancers can be treated. Possible treatments include chemotherapy, radiotherapy and surgery . The prognosis is influenced by the type of cancer and the extent of disease. While cancer can affect people of all ages, and a few types of cancer are more common in children, the overall risk of developing cancer increases with age. In 2007 cancer caused about 13% of all human deaths worldwide (7.9 million), and the number of cases is rising as more people live to old age.
