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. [ 3]
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 ]

Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these ...
The more different the cancer cells look compared to normal duct cells, the greater the risk of systemic spread. There are three characteristics that differentiate cancer cells from normal cells. Tendency to form tubular structures; Nuclear size, shape, and staining intensity; Mitotic rate - Rate of cell division

Acute erythrocyte leukemia is a rare form of acute myeloid leukemia (less than 5% of AML cases [ 1]) where the myeloproliferation is of erythrocytic precursors.

Oncology. Non-small-cell lung cancer ( NSCLC ), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [ 1][ 2][ 3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
