Cancer is the name given to a group of more than 100 diseases. What these diseases have in common is the rapid growth of cells in a part of the body. In a healthy body, the cells grow, divide and eventually die in an orderly fashion. Young people's cells divide faster, which allows them to grow. However, when a person has cancer, the cells start to grow out of control. Whereas normal cells would eventually die, cancer cells continue to grow and form new, abnormal cells that invade other tissues, something normal cells cannot do. DNA also plays a role in cancer. Each cell contains DNA that directs its action. This DNA can sometimes get damaged, but a normal cell can either repair that damage or the cell will simply die. In cancer cells, however, that DNA is not repaired nor does the cell die. Instead, these cells make new cells the body does not need, and these new cells contain the same damaged DNA. Eventually, these cells can form a tumor. While the reason for the initial damage to the DNA is often unknown, sometimes the damage can be linked to certain behaviors, including cigarette smoking. When cancer cells form, they often travel to other parts of the body. When that happens, these cells can form new tumors that replace the body's normal tissue. This process is known as metastasis. When detected early, before the cancer has metastasized, treatment is often successful. However, if the cancer has begun to spread to other parts of the body before it's been diagnosed, the survival rates are significantly lower.
