Overall survival rates for personascon blood cancer have doubled in the last 30 years due to increased eficaciaradiación and chemotherapy treatments . In 1960, only 4 percent of childhood leukemia niñosdiagnosticado survived. Today, it is expected that 79 percent devivir if they receive the best treatment available. Still, leukemia is the lídercausa of death by disease in children.
Adults are more likely to get lasniños blood cancer, and that risk increases with age. In 2003, sese estimates that about 106,200 Americans will be diagnosed with a blood lascánceres and about 57,500 die from the disease. Lymphomas representanaproximadamente 55 percent of new cases, leukemia 28 percent, and 14 percent mielomaaproximadamente. Less common forms of blood cancers account for about 3by percent of cases.
The real causes of cancer are unknown sangreaún. Scientists are trying to identify when and why the cuerpocomienza to produce abnormal cells and how those cells begin to invade the body blood desistema. How are you questions are answered, the information is used toimprove the prevention and treatment options.

Blood and lymphatic systems

the three types of cancers involve sangretodos uncontrolled growth of abnormal cells in the blood and médulamédula. To understand what happens in cancer of the blood, it helps to know a pocosobre the blood and lymph systems.
Blood carries ynutrientes oxygen to all organs of the body, aids in healing, and combat viruses, bacteria and other foreign material in the body. Blood is composed of:

• Plasma watery color amarillentofluido in which they are suspended and move through veins blood cells yarterias body.
• red blood cells , which contienela hemoglobin, a protein in the body that carries oxygen to body tissues
• Platelets more cells pequeñasque they are responsible for clotting.
• White blood cells (leukocytes), that protect the body from disease and infection

There are five main types delas white blood cells, including lymphocytes. Lymphomas derived from lymphocytes, which are made in the lymphatic tissue, including lymph nodes, spleen, thymus, tonsils and bone marrow. Lymphocytes constitute about 25 percent of all blood blancoscélulas. The number of circulating lymphocytes in the blood varies and puedeir either up or down when the body is fighting infection.
Lymph nodes are found along lymphatic delsistema, a network of thin tubes, similar to blood vessels, queramifican in all parts of body. The main groups of external node occur inthe neck, armpits and groin. Lymph nodes are enlarged when you have a enfermedado infection. For example, lymph nodes in the neck may hincharsecuando have a cold. swollen lymph nodes are often not a sign of a graveproblema, but this is also a symptom of lymphoma.
puedeno leukemia and multiple myeloma results in swollen lymph nodes.
Leukemia usually starts in bone elmédula. Myeloma originates from a cell line called plasma cells, bone marrow sonforma.
Responses to treatment andthe survival rates for each of these cancers also vary significantly.
The risk of developing the sangregeneralmente cancer increases with age. Males are more susceptible than women. Porquesu exact cause has not been discovered, no recommendations específicaspara prevent cancer of the blood, but you can follow the general guidelines. excessive radiation exposure wing and hazardous chemicals should be limited.

Radiation therapy is used for localized disease or to reduce tumor mass tamañola is compressing a vital body structure. Osease marrow transplants are becoming more frequent across the country. Newer treatments, such as biological therapies, was discovered at an exciting pace, and many of them sonya is routinely used in combination with other therapies.
bone marrow transplants. utilizadoscon more often to treat lymphoma and leukemia, this procedure is very altoLas doses of chemotherapy or radiation, which kills cancer cells but healthy cells tambiénlas bone marrow. then the patient is given an infusion of madrecélulas cells from bone marrow or peripheral blood. Bone marrow transplantation tieneenormes risks, including death, and tends to be more successful in the jóvenespacientes and when the disease is at an early stage. Since bone óseatrasplante of blood cancers is a specialized procedure, a candidate trasplantedebe find a hospital that has extensive experience in the specific sutipo treatment of cancer and performs bone marrow transplants regularly.

Biological therapy. BiológicaLa therapy uses special cells and immune system proteins to stimulate the body's immune desistema to kill cancer cells. Biological, such as interferons, interleukins, monoclonal antibodies, stimulating factors colony yfactores agents tumor necrosis natural substances found in the body ayudanalterar how the immune system reacts to cancer. Now, researchers are able decrear reproductions of some of these biological agents in laboratories. Estasreproducciones mimic natural immune agents, and are used to increase antitumor immune larespuesta patient.
