Cancer is a very dangerous disease. If it is not treated at the right time, then there are very few people who are able to avoid this disease. Cancer causes cells in any part of the body to divide uncontrollably. If it is in any one part of the body, then it spreads through that part to all parts of the body. When cancer occurs in one part of the body, it is called a primary tumor and after which the tumor that occurs in other parts of the body is called metastatic or secondary tumor.
