Leukemia or leukaemia (see spelling differences) is a cancer of the blood or bone marrow and is characterized by an abnormal proliferation (production by multiplication) of blood cells, usually white blood cells (leukocytes). Blood has different components sch as red blood cells, white blood cells, platelets and plasma. The red blood cells (rbc), platelets also called monocytes because it is belong to the "myeloid" group and other white blood cells belong to the "lymphoid" group. Lymphoid cells are affected. Disease progresses quickly. Blood cancer or Leukaemia is actually a group of diseases, each of which impede with the normal functioning of blood cells and progressively weaken the system.leukaemia is classified as either Acute or Chronic. Blood and urine samples may also be tested for various substances, called tumor markers, which may indicate cancer.Tumor markers are typically chemicals made by tumor cells, but tumor makers are also produced by some normal cells in your body. Lymphoid cells are affected. Disease progresses over a long period.Usually affects adults, more men than women.Myeloid cells are affected. Disease progresses over a long period of time. Causes of Blood Cancer
1. Exposure to radiation.
2. Exposure to chemicals.
3. Human T-cell Leukaemia Virus (HTLV)
4. Genetic factors (chromosomal abnormalities).
Symptoms of blood cancer
1. Tiredness.
2. Bleeding.
3. Bruising.
4. Fever.
5. Weight loss.
Treatment of Blood Cancer
Chemotherapy is destroy the abnormal cancer cells. This involves a bone marrow or a stem cell transplant.Stem cell transplant involves transplanting stem cells (the most basic type of cell, from which all types of blood cells develop), rather than bone marrow cells. Bone marrow or stem cell transplants allow much higher doses of chemotherapy to be given. Leukemia is a broad term covering a spectrum of diseases.Leukemia is clinically and pathologically split into its acute and chronic forms.Acute leukemia is characterized by the rapid proliferation of immature blood cells. This crowding makes the bone marrow unable to produce healthy blood cells. Acute forms of leukemia can occur in children and young adults.Chronic leukemia is distinguished by the excessive build up of relatively mature, but still abnormal, blood cells. Typically taking months to years to progress, the cells are produced at a much higher rate than normal cells, resulting in many abnormal white blood cells in the blood. Chronic leukemia mostly occurs in older people, but can theoretically occur in any age group. natural or artificial ionizing radiation.possible cause:
natural or artificial ionizing radiation
certain kinds of chemicals
some viruses
genetic predispositions
Leukemia, like other cancers, result from somatic mutations in the DNA which activate oncogenes or deactivate tumor suppressor genes, and disrupt the regulation of cell death, differentiation or division. Cohort and case-control studies have linked exposure to petrochemicals, such as benzene, and hair dyes to the development of some forms of leukemia.Viruses have also been linked to some forms of leukemia. For example, certain cases of ALL are associated with viral infections by either the human immunodeficiency virus (HIV, responsible for AIDS) or human T-lymphotropic virus (HTLV-1 and -2, causing adult T-cell leukemia/lymphoma).Fanconi anemia is also a risk factor for developing acute myelogenous leukemia.Until the cause or causes of leukemia are found, there is no way to prevent the disease. Cancer Prevention Measures
Enzymes to Dissolve Cancers
Dissolving cancerous tissue requires enzymes. Dietary supplements containing the ten or more pancreatic enzymes are helpful, with the most important enzymes being trypsin and chymotrypsin. These enzymes dissolve the protein coat of the cancer cell making it vulnerable to the attack of white blood cells. Pineapple and papaya are good sources of enzymes. Once the enzymes have dissolved the protein coating of the cancer cells, the white blood cells are able to recognize them as foreign cells.
Dietary sources of all kinds of enzymes are useful. The consumption of at least 70% fresh foods vs. 30% cooked foods helps ensure a supply of enzymes for the body (cooking at temperatures above 120ยบ F destroys enzymes in the food).
