On the occasion of World Cancer Day, on February 4, the Spanish Association Against Cancer (AECC), dedicates its celebration this year to the fight against childhood cancer due to the fact that cancer is currently the second most frequent cause of infant mortality in children aged between 1 and 14 years.
In Spain, after traffic accidents, cancer is the second cause of death childish. Today, both the incidence and prevalence of cancer in childhood are on the rise. An early diagnosis and more effective treatments are increasingly necessary.
Considering that all the organs of the body are made up of tissues, that tissues are made up of groups of cells, and that cells are responsible for the growth, evolution and renewal of organs and tissues, it is necessary to know that when there is a alteration in a cell, or when it has served its purpose and responded to the demand for organs and tissues, it dies.
If the cell survives, it will give rise to cells similar to it, different from the normal ones and, escaping the normal control mechanisms, it will proliferate, originating a set of "sick" and abnormal cells that will be located in a tissue or organ, and may travel through blood to other organs or tissues, causing tumors of many types and in very different locations.
By growing uncontrollably, the cell acquires abnormal sizes and morphologies, destroying neighboring cells, organs and bones, consuming part of the patient's nutrients and energy, and weakening the body's defenses.
Those diseased cells have been called Cancer, a disease that can appear at any stage of life, from birth and throughout the development of the human being.
Cancer is not a communicable disease. Cancer is an uncontrolled spread of cells in any organ or tissue, which originates when a group of cells escapes the normal mechanisms of control in terms of their reproduction and differentiation.
Statistics show that each year more than 160,000 children are diagnosed with cancer in the world. 80 percent of childhood patients live in developing countries.
According to the International Union Against Cancer (UICC), in developed countries, three out of four children with cancer survive at least five years after being diagnosed, thanks to progress in the diagnosis and treatment of this disease. In developing countries, more than half of children diagnosed with cancer are likely to die.
According to the International Agency for Research on Cancer, the most common childhood cancers are: leukemia (cancer of the white blood cells), followed by Lymphoma (cancer of the lymph nodes), brain tumors (cancer that can occur in many parts of the brain), and Osteosarcoma (bone cancer).
Tumors account for 80 percent of all cases. Leukemia is the most common childhood cancer and there are several types. The most common in children are acute lymphoblastic leukemias, and they are usually suffered by children between the ages of 2 and 8 years.
After leukemia, nervous system tumors they are the second most common type of cancer in childhood. They can occur between 5 and 10 years of life.
And thirdly, there are lymphomas, which are cancers that develop from the lymphatic system. Less commonly, children develop cancers of the small intestine, liver, spleen, nervous system, and bone marrow.
