Answer

Cancer is a common name for a group of diseases characterised by uncontrolled proliferation of abnormal cells. Human body is made up of several organs, which are constituted of specific characteristic cells. Cells divide for growth of an organ, for repairing tissue damage and to maintain functions of the organ. The daughter cells are the exact replica of their parent cells. Sometimes due to either some faulty mechanism or some factors that are unknown yet, the daughter cells become abnormal and unlike their parent cells. They donâ€™t discharge the same functions but requires the same nutrition like the normal cells. These cells again divide to produce a large number of abnormal cells for which human body organs do not function normally and his nutrition is impaired rapidly. These cells cluster to form lumps, swellings, and sometimes produce ulcers in the respective organs, which we call as cancer. However, in case of blood cancer (Leukaemia), the abnormal cells start circulating in the blood stream and thus no visible lump or swellings are observed. Cancer is known by its different types like sarcoma, lymphoma, leukaemia, myeloma, carcinoma etc. Its most important characterisitc is that the cancer cells breakaway from the tissue or organ of origin and starts spreading to other parts of the body through lymphatic channels or cavities or blood vessels. They lodge in other parts of the body organ and grow. This is known as metastasis. Because of this unique characteristic, it becomes difficult to cure or to control cancer when it has spread.
