| Properties of Cancer Cells |
|
| 1) Cancer cells show uncontrolled mitotic divisions causing unorganised growth |
| |
| 2) Due to uncontrolled growth and division of cells, a tumour (also called Neoplasm is generally formed) |
| |
| 3) Cancer cells are far less adhesive than the normal cells, so these generally wander through the tissues to cause cancerous growth in different parts of the body. |
| |
| This ability of cancer cells to invade new sites is termed as Metastasis. |
| |
| 4) Cancer cells exhibit a number of alterations on cell surface, in the cytoplasm and in their genes. |
| |
| 5) Cancer cells donot undergo differentiation |
