Benzene

BenzeneA sweet smelling, highly toxic hydrocarbon. Long-term exposure to benzene is known to cause anemia and leukemia. The anemia associated with benzene exposure is termed aplastic anemia. The types of leukemia associated with benzene exposure are adult acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL). It is thought that benzene induces DNA damage in hematopoietic stem cells that give rise to leukemic clones of cells.

It is thought that benzene induces DNA damage in hematopoietic stem cells that give rise to leukemic clones of cells.
Anemia
Anemia is a condition in which a deficiency in the size or number of erythrocytes (red blood cells) or the amount of hemoglobin they contain limits the exchange of oxygen and carbon dioxide between the blood and the tissue cells. Most anemias are caused by a lack of nutrients required for normal erythrocyte synthesis, principally iron, vitamin B-12, and folic acid. Others result from a variety of conditions, such as hemorrhage, genetic abnormalities, chronic disease states or drug toxicity.
Leukemia
Cancer of white blood cells. Acute leukemias are characterized by the presence of "blasts," which are immature white blood cells. Large quantities of blasts generally overgrow the bone marrow, leaving very little space for normal bone marrow cells. This type generally requires immediate treatment. Chronic leukemias are those characterized by a large and uncontrolled growth of more mature white blood cells. These types of leukemias tend not to progress as rapidly, and treatment is often milder than that of acute leukemias.
Acute
1. Of short course. 2. Severe, but of a short duration. Not chronic.
Chronic
Ongoing or recurring. Chronic medical conditions include diabetes, epilepsy, and chronic fatigue syndrome.

PREVIOUS AND NEXT TERMS--------------------------------------
Benign paroxysmal positional vertigo (BPPV)
A balance disorder that results in the sudden onset of dizziness, spinning, or vertigo when moving the head.
Benign prostatic hyperplasia
Abbreviated BPH. A noncancerous prostate problem in which the normal elements of the prostate gland grow in size and number. Their sheer bulk may compress the urethra, which courses through the center of the prostate, impeding the flow of urine from the bladder through the urethra to the outside. This leads to urine retention and the need for frequent urination. If BPH is severe, complete blockage can occur.
Benign recurrent aseptic meningitis
Recurring meningitis without identifiable cause that leaves no residual damage to the nervous system. Benign recurrent aseptic meningitis is also called Mollaret meningitis.
Benign sleep myoclonus
A distinctive disorder of sleep in infancy characterized by rhythmic myoclonic jerks (sudden muscle contractions) which occur when the child is asleep and which stop when the child is awakened. Sleep myoclonus usually disappears after a few weeks, in most cases by 3 months of age, as the sleep patterns mature. Benign sleep myoclonus may be mistaken for epilepsy.
