Leukemia Basics
Leukemia is a cancer of the blood and bone marrow, which are two organs responsible for making and maintaining blood cells. There are several types of leukemia, each characterized by different characteristics in the blood and bone marrow.
Key Characteristics of Leukemia:
Increased blood cell count: The blood contains more than usual number of blood cells, including white blood cells, red blood cells, and platelets.
Impaired regulation of immune response: This allows cancer cells to evade detection and destruction by the immune system.
Presence of abnormal cells: Leukemia cells have the ability to develop into abnormal cells that can replace healthy blood cells.
Genetic abnormalities: Many types of leukemia are caused by mutations in specific genes that regulate blood cell production and function.
Types of Leukemia:
Acute lymphoblastic leukemia (ALL): A type of leukemia characterized by rapid growth and transformation of abnormal blood cells.
Chronic lymphocytic leukemia (CLL): A type of leukemia that develops gradually and has a lower growth rate than ALL.
Chronic myeloid leukemia (CML): A type of leukemia that starts in the blood-forming cells in the bone marrow and then spreads to other parts of the body.
Chronic idiopathic leukemia (CIL): A type of leukemia that has an unknown cause and develops slowly over time.
Causes of Leukemia:
Environmental factors: Exposure to radiation, chemicals, and certain viruses may be linked to leukemia development.
Genetic factors: Some individuals have a higher risk of leukemia due to genetic mutations.
Unknown cause: The exact cause of leukemia is unknown in many cases.
Treatment for Leukemia:
Chemotherapy: This involves the use of drugs to kill cancer cells.
Radiation therapy: High-energy X-rays or other forms of radiation are used to target and destroy cancer cells.
Targeted therapy: Drugs are designed to target specific molecules or pathways involved in leukemia growth and survival.
Immunotherapy: This approach helps the immune system recognize and attack cancer cells
