What is causes of cancer?
Cancer does not have a single cause. Scientists believe that cancer is caused by the interaction of many factors together. The factors involved may be caused by genetic, environmental or constitutional an individual.
Diagnosis, treatment and prognosis of cancer in children are different than adult patients. The main differences are in the survival rate and cause cancer. The survival rate of children with cancer is 79 percent, while the adult is 64 percent. It is believed that this difference is that children respond better to therapy and can tolerate more aggressive therapy, so the prognosis is better.
Often, childhood cancers occur or begin in stem cells, which are simple cells capable of producing other types of specialized cells that the body needs. Normally, childhood cancer is motivated by a cell change or mutation sporadically (by chance). In adults, epithelial cells are most likely to become cancerous. These cells line the body cavity and the body surface. Cancer is caused by environmental exposures to these cells over time. For this reason, cancer in adults is called “acquired”.
