what is leukaemia cancer .?

Answer 1

Leukemia (or leukaemia) is a cancer of the blood or bone marrow characterized by an abnormal proliferation of blood cells, usually white blood cells (leukocytes). It is part of the broad group of diseases called hematological neoplasms.Damage to the bone marrow, by way of displacing the normal marrow cells with increasing numbers of malignant cells, results in a lack of blood platelets, which are important in the blood clotting process. This means people with leukemia may become bruised, bleed excessively, or develop pinprick bleeds (petechiae).

White blood cells, which are involved in fighting pathogens, may be suppressed or dysfunctional, putting the patient at the risk of developing infections.

Foryour information I am giving the causes for getting this disease-
No one knows what causes leukemia. Researchers have strong suspicions about four possible causes. They are radiation, chemicals, viruses, and genetic factors. 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. These mutations may occur spontaneously or as a result of exposure to radiation or carcinogenic substances and are likely to be influenced by genetic factors. Cohort and case control studies have linked exposure to petrochemicals, such as benzene, and hair dyes to the development of leukemia.

Viruses have also been linked to some forms of leukemia. 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).-

Answer 2

Leukaemia is a cancer that affects the bone marrow. The bone marrow makes blood cells. Blood is mostly made up of plasma. Floating in the plasma are:

Red blood cells - that carry oxygen around the body
White blood cells - that fight disease and infection
Platelets - that help to stop bleeding when it starts.
In people with leukaemia, the bone marrow produces large numbers of abnormal white blood cells. The abnormal white blood cells crowd into the bone marrow, so the marrow can't make enough normal red blood cells, white blood cells and platelets. About 570 Victorians develop leukaemia every year.

Answer 3

Leukaemia is cancer of the blood cells, which usually affect the white blood cells.

Answer 4

Cancer is a broad range of conditions characterized by the cell growth of certain cells suddenly becoming uncontrolled, causing failure of those cells primary function, any organ they are part of, and often tumors where they are located.

Leukemia is a cancer of the blood cells, so it typically affects the whole body. It is not good news, but it need not be the end of the world, either; progress is made daily in treating all kinds of cancers, if you know someone who has been diagnosed with some kind of blood cancer, send them here:

The Leukemia & Lymphoma Society is the world's largest voluntary health organization dedicated to funding blood cancer research, education, and patient services. The Society's mission: Cure leukemia, lymphoma, Hodgkin's disease and myeloma, and improve the quality of life of patients and their families.

Answer 5

Leukemia is not cancer. It is a malignancy of elements of the blood forming organs in the bone marrow.

Answer 6

Leukemia ("white blood") = malignant tumor (cancer) of the bone marrow.
Another meaning: leukemia = malignant lymphoid or bone marrow cells found in blood

There are many different types of leukemias. Some are very bad, aggressive, some wil rarely kill you.
So, leukemia is not one disease.

Answer 7

Leukemia is cancerous cells in the blood.

Answer 8

cancer of the blood

Answer 9

as far as i can remember, it is a condition where there is an increase number of the white blood cells more that the red blood cells. this condition is detrimental to one's health because the
supply of oxyginated blood to all body parts is less thus the pale
appearance of the patient is evident.

Answer 10

I think that's cancer of the blood.
