The growth of multicellular animals occurs due to addition of new cells. The old or existing cells divide by mitosis to form new cells.
This division is controlled and regulated by some factors. Sometimes, due to unknown reasons, some cells divide in abnormally faster rate to form a lump. This lump increases rapidly causing ulcers. It causes serious complications in the body. These abnormal cells first destroy the organ and then the whole body. These cells utilize the total food of the body. So the affected person becomes weak, looses his weight and ultimately dies.

Though cancer can develop at any part or organ of the body, it mostly develops in some organs like liver, alimentary canal, larynx, pharynx, tongue, lips, gall bladder, lungs, uterus, urinary bladder, lymph nodes, bones etc.
Normal cells of the body have a control over the division. The controlling factor is present in the DNA. The DNA directs the cells to divide and stops the division when not required. In cancerous cells the controlling factor is not present, probably due to mutant genes. Due to absence of controlling factor, the mitosis continues uncontrolled and forms cancer. It is believed that these cells carry certain cancer causing genes, called oncogens.
These oncogenes remain inactive. Certain conditions initiate these genes to multiply and destroy the normal controlling factor of the cells. The role of virus is strongly suspected now.
The cancer which occurs in muscles, cartilages, bones, blood vessels, connective tissues are known as sarcoma. 2. Carcinoma: This type of cancer originates from skin or cells which lines the internal organs.
