Most people hear the verdict at the time of cancer from a doctor like to hear the death knell. Cancer is indeed one of the most frightening diseases because of abnormal cells that grow uncontrollably and can not be spread throughout the body and damage the normal cells that exist around it.

At present there are about 200 types of cancer. However, there are characteristics of all the existing cancer growth and spread of abnormal cells that are not controlled. Which is often the question is why cancer can develop in a person while in others it is not yet known with certainty.

In this case researchers estimated 5-10 percent of cancers are caused by heredity factors. This means the cancer down from generation to generation through genes that are not normal. But in some major cases, cancer develops through different stages of a complex that includes excessive exposure due to cancer-causing substances, such as tobacco or the sun.

Carcinogens or a cancer-causing substance is believed to cause the formation of free radicals that would damage the strands of DNA molecules carrying information on how to reproduce. At the moment there is DNA that is corrupt; the cancer cells will be formed.

Therefore the only way to prevent cancer is by reducing exposure to anything that can stimulate the formation of free radicals, including foods rich in fat, tobacco, and alcohol. Cancer can develop into several forms, namely:
