The cause of cancer is not as simple as that. Cancers are not caused by just one gene. Cancer is usually an illness of older people and most cancers occur when several genetic changes occur in a cell. This is called sporadic cancer. But some people inherit faulty (mutated) genes which make their chance of developing a particular cancer higher than normal.
